    Innovations for quality control and process optimization
    Plants & Machinery  AI, Robot, Industry 4.0

    Measuring, control, inspection, sorting, and analysis systems from an extensive product portfolio The wire 2018 will take place from April 16 to 20, 2018, in Düsseldorf and again, SIKORA will present innovative measuring, control, inspection, sorting, and analysis systems from its extensive product portfolio. On the exhibition booth 9A41, with a space of 200 m² (240 y²) on two levels, visitors can discover the most recent technological innovations for quality control and process optimization for the wire and cable, optical fiber as well as plastics industries. X-ray technology measures diameter, wall thickness, and concentricity for the medium and high voltage cable production A highlight at the SIKORA exhibition booth is the X-RAY 8000 NXT – the worldwide industrial standard for quality assurance of medium, high and extra-high voltage cables in CV lines. It measures the concentricity, wall thickness, diameter, and ovality of up to three layers of XLPE and EPR isolated cables during production. Measuring values for the centering of the injection tools and control are available immediately after the starting of the line. The multi-sensor technology (MST) and two high-speed scanners ensure a reliable online measurement. With each single scan, the MST measures the movement of the cable, compensates vibrations and provides double the number of measurements. Measurement of wall thickness, concentricity, diameter, and ovality in jacketing lines For continuous quality control during the insulation or jacketing of conductors and cables, the X-ray measuring devices X-RAY 6000 as well as X-RAY 6000 PRO are recommended. Both systems precisely provide reliable measuring values regarding diameter, wall thickness, concentricity as well as ovality for a reproducible product quality. Layer thicknesses of any kind of material are measurable. A maximum of productivity is achieved by the automatic control of line speed and extruder rpm. Diameter measurement on the highest level In extrusion lines, the devices of the LASER Series 2000 and LASER Series 6000 are indispensable components for a diameter measurement on the highest level. Furthermore, the classic and high-end devices are used in rewinding lines for the wire drawing. They stand out by their high precision and continuous functionality without calibration or maintenance times. Due to up to 5,000 measurements per second/per axis, the LASER Series 6000 impresses with the highest single value precision for an efficient line control. The integrated lump detector function ensures a detection of irregularities on the product surface of transparent and non-transparent materials. In addition to standard interfaces, the device series provides OPC UA, and therefore, is best equipped for “Industry 4.0”. Safety for every cable production SIKORA offers a complete program of direct current (DC), high frequency (HF) and alternating current (AC) spark testers. Already during the extrusion, the insulation of wires and cables is tested with the high voltage testing devices and possible insulation faults are detected and documented in a timely manner. Further application areas are rewinding lines. For the testing, the dry cable running through the bead chain electrode of the spark tester is exposed to the selected test voltage. Therefore, faults in the insulation are reliably detected. Measurement of concentricity, diameter, and ovality With the CENTERVIEW 8000, SIKORA presents a measuring system for the non-contact, online 8-point-eccentricity, 4-axes-diameter and 8-point-ovality measurement of coax cables, LAN cables as well as automotive and installation cables to the global public. Technical highlights of the CENTERVIEW 8000 are the graphic visualization of measuring values as a scatter plot that shows the distribution of short-term variations as well as the automatic positioning of the gauge head to the cable position for highest reliability. A further feature is the measurement of micro-coax cables with a diameter range from 0.1 to 10 mm (0.004 to 0.4”). Online quality control of optical fibers in the drawing tower By means of a drawing tower model, SIKORA presents live its broad portfolio of measuring systems for quality control of optical fibers at different positions. There will be systems presented for the measurement of the diameter and the position of the naked and coated fiber as well for the determination of the tension. Furthermore, gauge heads are displayed for the measurement of the fiber temperature at the hot position of the drawing process, to determine the fiber temperature for the control of the furnace, and at the cold end, to exactly dose the Helium used for the cooling, and therefore, to save costs. In addition, a gauge head for the measurement of the concentricity of the coating as well as for the detection of lumps on the surface of the coated fiber is exhibited. Online inspection and sorting of XLPE and semiconductor pellets A further highlight at the wire is the PURITY SCANNER for online inspection and sorting of plastic pellets that are used for the insulation of medium, high and extra-high voltage cables as well as onshore and offshore cables. The unique combination of an X-ray camera with an optical camera system is currently the only technology that reliably detects contamination on the surface as well as inside of plastic pellets. Contaminated pellets are automatically sorted out. Offline inspection and analysis of pellets, flakes, and films/tapes SIKORA engineers developed the PURITY CONCEPT Systems for small material throughputs and applications where sample testing or an incoming goods inspection is sufficient. These analysis devices are alternatively equipped with X-ray technology, optical cameras or infrared sensors and detect contamination in pellets, flakes, and tapes. For example, the PURITY CONCEPT Systems are used to analyze pellets that have been detected and sorted out by the PURITY SCANNER. Another typical application is the testing of tapes that are used when manufacturing factory joints. The interplay of online and offline inspection and analysis provides an absolute control of the material purity as well as the development of a database to further improve processes and avoid future contamination. Further devices at the SIKORA exhibition booth LUMP 2000: Measuring technology for the detection of lumps and neckdowns in two or three measuring planes with double sensor technology ULTRATEMP 6000: Non-contact temperature measurement of the polyethylene melt CAPACITANCE 2000: Innovative capacitance measurement with multi-zones technology as well as integrated FFT and SRL analysis Display and control systems: Powerful ECOCONTROL 6000, 1000, and 600 processor systems as well as low-cost display and control devices REMOTE 2000 and DISPLAY 2000 Premiere of innovative measuring technologies for online quality control of steel tubes For more than ten years SIKORA has been successfully active in the plastics market. The applied technologies for quality control measure and control online product parameter such as diameter, ovality, wall thickness as well as eccentricity for the highest quality of the end product and optimal process efficiency during the production. The operator’s advantages that result from using SIKORA measuring systems, suggested the proven technologies to be transferred to the steel market. Thus, SIKORA is going to exhibit for the first time a broad portfolio of innovative systems for non-destructive quality control and process optimization during production of steel tubes at its booth 6/J32. Diameter and ovality measurement of steel tubes by means of millimeter waves based radar technology The SIKORA S-WAVE 6000 is based on progressive, high resolution radar technology and represents an innovative alternative to the optical triangulation technology. The advantage of radar technology is that reliable measuring values are generated even under difficult environmental conditions. Therefore, the automotive industry uses in the area of autonomous driving radar technology guaranteeing reliable measuring values under all weather conditions. The S-WAVE 6000 measures online and contactless, simultaneously from several directions the diameter and ovality of steel tubes. In addition, in this way fast rotating steel tubes can be precisely measured. The system requires neither coupling media nor a calibration. The temperature of the tube has no influence on the measurement. Due to the slim design the S-WAVE 6000 can easily be integrated in the production process in arbitrarily large distance to the tube. The S-WAVE 6000 is even able to provide reliable measuring values when the tube moves outside the center of the measuring head. The technology is suitable for blank, rough as well as cold or warm surfaces. Thickness measurement of steel plates by means of millimeter waves technology Radar technology based on millimeter waves additionally convinces with the measurement of the thickness of steel plates. Similar to the optical triangulation method the distances to the steel plates are measured at the top respectively at the bottom. The advantage is that the radar waves are directed over a reflector on the product to be measured, thus the radar transceivers carry out the measurement from a protected position. Dust, steam and even dripping water do not influence the measuring result. For this application as well, surface quality is no issue with the result that blank, rough, cold and warm surfaces are precisely measured. Wall thickness measurement of plastic coated steel tubes by means of X-ray and millimeter waves technologies At the Tube SIKORA also showcases systems for the measurement of plastic coated tubes on the basis of X-ray and millimeter waves technologies. A plastic coating is among others applied at freely installed, underground and under water laid steel tubes for corrosion protection. For the joining of produced tubes compliance with specified dimensions for example for the wall thickness is essential. Therefore, for the measurement of the wall thickness of the plastic coating, SIKORA‘s X-ray based X-RAY 6000 PRO for tubes with a diameter up to 200 mm is used. For larger dimensions the previously described S-WAVE 6000 is used. Both methods are independent from the material of the product to be measured and the temperature, they do not require coupling media and no calibration. Immediately with the online measurement precise measuring values are accessible. These are visualized at the monitor of the processor system ECOCONTROL 6000 and allow the operator, if required, to intervene in the process for optimization. Thus, SIKORA systems are essential components to ensure the highest quality and an efficient process during the manufacturing of plastic coated steel tubes.

    New impetus for the tube and wire industry
    Industrial Goods  Steel pipe

    SMS group puts digitalization in the spotlight at Tube & wire 2018 We see digitalization and Industry 4.0 as key challenges that are set to profoundly change the tube and wire industry in the years to come. SMS group (www.sms-group.com) is turning the spotlight on these topics at the Tube & wire trade fair, which will take place in Düsseldorf from April 16th to 20th, 2018. Hall 7a, booth B03/B04, is where SMS group will be looking at how digitalization is changing the whole value-added chain and enabling greater efficiency, higher quality, and more flexibility from a number of different angles. The first impetus arising from digitalization and Industry 4.0 concerns the design and manufacture of machines and components for the production of tube and wire itself. At the fair, SMS group will be demonstrating this using the example of a mill stand for a cold pilger mill, which is made with the aid of additive manufacturing processes. The component geometry of a mill stand, which up to now has been made by machining techniques, was optimized in terms of the stresses generated so that the number of strokes and thus the productivity were enhanced significantly. Further examples of SMS group’s activities in the additive manufacturing growth market, which are to be shown at the fair, are the competence center for 3D printing, which is being built in Mönchengladbach, as well as 3D printed components. They show an enhanced functionality, they weigh less and have shorter delivery periods. The second topic shows the possibilities that digitalization offers for the production process. The aim of the “smart mill” is to use data and the corresponding parameters as a basis for business and process control related decisions. A realistic map of the process with precise measurements is required for the collection of reliable process data. This type of measuring system for tube, pipe, bar, and section mills is to be displayed by SMS group at Tube & wire in cooperation with TBK Automatisierung und Messtechnik GmbH, an SMS group company. The system measures up to 5,000 contours per second with laser light section sensors during the rolling process. Local atypical anomalies on the surface can be detected on the basis of the 3D models, generated by high resolution cross-sectional measure­ments. The direct transfer of the measurement readings to the mill stand control system allows roll setting adjustments to be made during the rolling process and thus saves time and money by directly monitoring the production process. Digitalization is also creating new opportunities for plant service. "Smart Maintenance Solutions" are aimed at enhancing the availability of the plant and the quality of the end products on a long-term basis by combining software solutions. The creation of a digital plant structure will offer maintenance teams centralized access to all the relevant parameters in future. The information required will be provided, for example, by the eDoc electronic parts catalog, the IMMS® (Integrated Maintenance Management System), or the Genius CM® system (Condition Monitoring). What’s more, the link to “smart” training courses will also be presented at the fair using augmented reality. Digital products and platforms round off the range of presentations at Tube & wire 2018. They form the basis for intelligent, digital services, and implement the secure, digital exchange of information between SMS group and its customers. One example is the platform for PQSC® piercer plugs for seamless tube rolling mills, through which you can process orders and check the status of each order 24 hours a day. Not only that, a comment function ensures easy communi­cation, as notes referencing the relevant customer order and SMS group employee can be entered. The option of order-based communication means the whole process is more transparent, change requests are easier to follow, and orders can be split if different delivery times for partial deliveries are required. However it is not just technological boundaries that will be redefined by digitalization. The way we work with customers and other partners will change, with cooperation becoming even closer in future. As the “Leading Partner in the World of Metals” SMS group is getting together with customers to present projects at this fair that highlight this successful cooperation in the areas of new plant construction, revamps, and service.

    OTEC has developed several surface finishing processes of threading tools During the manufacturing of metal workpieces very often it is necessary to machine threads. Mainly when the workpieces have to be mounted or assembled to other parts screw connections are unavoidable. Generally, there are two different ways to create threads: cutting (‘taps’) which is the most popular one and forming (‘forming tools’). Thread forming has the advantage that the microstructure is just deformed. In this way the fibre flow is not broken, which is increasing the material strength and extraction force. As different as the processes for thread cutting and thread forming are, as different are the requirements to the tools. During the manufacture of taps, the grinding process creates burrs between the thread profile and the chip flute. Bur-free grinding is simply not possible, so extensive finishing is absolutely essential. If the taps are not deburred, then adverse effects on the geometry of the cutting edge cannot be excluded. What is more, burs on uncoated tools can interfere with the cutting edge during chip removal or break off and damage the cutting edge and thereby considerably reduce tool life, impair the quality of the surface and degrade dimensional stability. Even in the case of thread formers, the conventional production process leaves traces on the tool surface. This results in fine grinding ridges, which have a negative influence on the friction between the tool and the material to be deformed. The ridges also favour the fixing of the material in the forming grooves. OTEC has developed several surface finishing processes of threading tools. In stream finishing machines with pulse drive (Pulsfinish) the tools can be processed reliably, quickly and economically according to the requirements. The principle of pulse finishing system is based on the precisely defined and rapidly repeating relative movement between media and workpiece. Here the clamped workpiece is immersed in the media stream of the rotating drum where it is quickly accelerated to a speed of over 2,000 rpm. Then it is decelerated again and accelerated once more. The differing speeds resulting from the inertia of the media in the drum and the rapid change of workpiece speed give rise to an extremely intense and precisely controllable abrasive effect. Compared to conventional processing methods, several production steps can be saved using the pulse finishing process. Deburring, smoothing and rounding of the edges in one operation enable time and cost savings. A surface which has been treated with the OTEC process also improves the adhesion of the subsequent coatings and extends the tool life. Cutting tools Deburring of taps Taps in general need a deburring process after the tool grinding. With the conventional brushing method, never all burrs can be removed, which affects the later coating negatively. Non-removed burrs break off and create uncoated areas that wear more quickly. In OTEC’s stream finishing machines with pulse drive (Pulsfinish) workpieces can be deburred within several seconds up to some minutes. Defined rounding of taps Cutting edges can be rounded to a defined measurement. By setting the parameters container and workpiece rotation speed as well as the immersion angles the geometry of the taps can be modified in order to match the requested and optimal shape. Forming tools Defined smoothing of forming tools The requirement is mainly to flatten the surface. The main task when machining thread formers is to evenly smoothen the entire tool surface. A smooth surface reduces the formation of material in the forming grooves and reduces the friction between the tool and the material to be deformed. Depending on the requirements, the defined rounding of certain functional edges is also necessary. By using a surface finishing process by OTEC it is possible to match such requirements. Compared to competing processes (e.g. shot blasting) the OTEC process is pricewise very interesting and at the same time quite flexible, as it adapts to different workpiece shapes. By this finishing process, the deformation forces can be reduced by about 60%. The use of the stream finishing machines with pulse drive (Pulsfinish) is giving the possibility to work with high energy and small and abrasive media. The finishing target is achieved in about 1 to 2 minutes, depending on the size of the tap and the requested result. The media used is also smoothing the surface of the tools which is giving advantages in the coating behavior and tool life. The process is very flexible and adapts to every dimension and shape of taps. At the same time, the wearing of the media is low, what makes the process quite economical. In addition stream finishing machines from OTEC are highly economical since a single machine can process a large number of workpieces at the same time, depending on the requirements of the job in hand. Workpieces can be changed quickly with automatic door or even automatically by robot.

    Leoni’s key technology LEONiQ makes cable solutions intelligent Leoni, a global provider of energy and data management solutions in the automotive sector and other industries, has developed an intelligent cable technology that makes energy and data flows more efficient, secure and available. “LEONiQ” can record and evaluate such differing parameters as temperature and mechanical wear along almost any given cable system. This key technology facilitates drawing conclusions concerning the condition of the overall cable system as well as controlling and monitoring it. For the first time, therefore, it is not just the connected becoming intelligent, but also connectivity itself. Size and price set new standards. Leoni will be presenting to the public for the first time on Microsoft’s booth at the Hanover Messe trade fair how the technology works and what benefits it brings to users and cooperation partners. „The megatrends of energy distribution and data management are the field in which Leoni has been established and operating for decades as a well-known manufacturer. The Company is now transforming from an experienced cable producer to be a technology partner to its customers – while making use of the opportunities of the digital age for the benefit of its customers and partners,” states Bruno Fankhauser, member of Leoni AG’s Board of Directors with responsibility for the Wire & Cable Solutions division. The objective is to offer intelligent, customised and trail-blazing solutions. LEONiQ makes a crucial contribution in this respect, comprising three main elements: Simulation for energy and data transmission: As early as the initial development phase, LEONiQ uses digital functional simulation of cable solutions to design them best for the respective application. Sensor-integrated, intelligent connectivity solutions: The technology enables a new kind of monitoring function to be integrated in system-critical applications with sensor and electronic elements along the cable system. It continuously reads such different parameters as temperature, impermeability, mechanical stress and GPS position. Data analysis and smart services: Algorithms in the cloud analyse the data, which the user can view on a dashboard; if need be, almost in real time. This process allows for a range of data-based smart services including early warning systems, active system control and pinpoint recommendations for action. There is consequently complete transparency across all cable systems equipped with LEONiQ – no matter where in the world, no matter in which application. The recorded data is also fed into the functional simulation models. Thanks to this control loop, Leoni is able to steadily optimise all intelligent cable solutions in what is a kind of learning system. New options for the user This Leoni-developed technology combines the advantages of other, sometimes very costly measuring methods inside a very small space while simultaneously providing access via the cloud at any time: LEONiQ is about 100 times cheaper and 100 times smaller than comparable technologies and makes the use of intelligence in cables economically feasible for the first time. That gives the user considerable added value, which is based on the cable system’s true usage data as well as its evaluation and interpretation. This, in turn, facilitates such applications as predictive maintenance, pay-per-use models and overall system monitoring and control. Application example: Charging electric cars becoming safer and more efficient Leoni can add intelligence to virtually any cable. The infrastructure for charging electric and plug-in hybrid vehicles is one example for use of the LEONiQ key technology. Here it can contribute to monitoring and optimising high-voltage charging cycles. For instance, based on sensor data from the charging station and the vehicle battery combined with the cable’s temperature, every charge can thus be run at the maximum possible power at all times. The vehicle is consequently more safely and quickly charged, and a fault is thoroughly identified before it becomes an actual problem – benefiting the user and the charging station operator.

    The WAFIOS G 450 Spring End Grinding Machine Designed in Reutlingen, Germany, and drawing on expertise cultivated by WAFIOS there over the decades, a new generation of machines is being produced at WAFIOS' production company in Zhangjiagang, China, for the first time. The G 450 features the latest version of WAFIOS' WPS 3.2 EasyWay high-end control system, which has already proven its worth as one of the company's highly successful products. The new generation of machines has been developed with two key aims in mind: to provide a solution that addresses the needs of as many customers as possible, even if they opt for simply the basic version, and to deliver outstanding value for money. In April of this year, the spring end grinding machine made its live debut in front of an audience made up of Germany's experts in the field at the WAFIOS In-House Exhibition in Wuppertal. The G 450 is a single-plate spring end grinding machine for grinding both compression spring ends simultaneously using the crush-grinding or down-feed grinding technique. The machine's design combines proven technology with innovation: While the team of developers at WAFIOS was able to draw inspiration from successful solutions from WAFIOS' G6 range, already on the market, it also pursued entirely new directions during the development process. Designed for common applications and optimized production output while maintaining outstanding quality The basic version of the G 450 comes with 8 axes (6 servoaxes and two frequency-controlled drives) that are used for driving and down-feeding the upper and lower grinding wheel, driving the loading plate, the horizontal and vertical axes of the dressing unit, and driving the protective shield. It also features a high-performance cooling and dust extraction concept as well as a rigid dressing unit with 2 axes. Thanks to its protective devices, the G 450 meets the requirements for CE conformity, particularly when it comes to the harsher conditions associated with the type-C standard for grinding machines. The infinitely adjustable rotating speed of the grinding wheels, which ranges between 35 and 50 m/s, and the powerful, frequency-controlled three-phase motors (7.5 kW) for driving the two grinding spindles, enable the G 450 to achieve the very best levels of production output. The new and highly robust machine design for grinding springs and for dressing grinding wheels ensures that quality remains consistently good. The extraction channel has been positioned tangentially to the grinding wheel and thus improves the extraction of grinding wheel dust. Other features of the basic version are laser sensors for automatic grinding wheel positioning, ensuring wear compensation, plus a spring length measuring device for in-process monitoring. Innovative solutions for eeducing cycle times and downtimes The machinery system comes with numerous devices that are designed to assist the operator in the process of using it, ensuring excellent availability coupled with low operating costs. Not only that, but the high-performance automatic dressing system also reduces downtimes. Thanks to the position of the dressing unit on the right-hand side, only minor soiling occurs during the dressing process. The extraction channel, meanwhile, is located in a place that makes it possible to extract grinding wheel dust as soon as it appears. The rigid design of the dressing slide ensures that a consistently high level of dressing quality is maintained throughout the entire stroke. Even dressing at an angle is possible thanks to the control concept based on 2 servoaxes. The software package required for this is available to order as a separate option. In most cases, grinding wheels used in a dressing process are positioned so that they are parallel to one another (known as the down-feed grinding technique). However, this can result in springs in the outermost row of the loading plate being ground to a shorter length than springs that are positioned further toward the inside. The reason for this lies in the shorter grinding path that the springs on the inside of the loading plate experience (in other words, a smaller radius). Positioning either one grinding wheel or both at an angle, so that the distance between the grinding wheels at the central point is 1-3 mm larger, solves this problem as the lower contact pressure exerted during grinding compensates for the longer path that the outer springs experience. Another feature designed to help the operator is the viewing window in the protective hood, which makes it easier to perform visual monitoring of the grinding process. The extraction and ventilation concept, with an extraction channel installed in the perfect position, is a crucial part of what makes the machine's availability so good. It is positioned as far as possible toward the front, directly behind the dressing system, and tangentially to the grinding wheel in order to prevent deposits in the grinding room as far as possible. The design of the grinding room itself features optimized flow characteristics and ensures that the extraction volume is kept even at all times. Two fans generate an air shower for actively cooling the grinding room during the grinding process, making it possible to take advantage of maximum speeds while at the same time reducing deposits. Highly resistant to wear, the grinding table plates can be turned around in the entry and exit area and can thus be used on both sides. They have a significant role to play in cutting downtimes and operating costs. The pneumatically driven ejection flap enables the springs to fall down through the grinding table. A special lift-out device makes it easier and safer to change the grinding wheels in an ergonomic way, while the optional balancing device helps the machine to perform its functions reliably by making it possible to minimize any imbalance in the flange-mounted grinding wheels as a preparatory measure. Available as an option, the particulate deflector reduces and prevents deposits in the grinding room thanks to a special alloy that is applied to the G 450's extraction channel lining. This feature also provides advantages due to the alloy components preventing the build-up of deposits, and the ability of the extraction system to remove dust from the grinding room. This means that no tools are required for removing deposits, machine availability is increased, and there is no need for frequent cleaning. Modern Operating Concept - High-End WAFIOS WPS 3.2 EasyWay Control System The WAFIOS G 450 is controlled using a 21.5" multitouch screen, and comes installed with the WAFIOS WPS 3.2 EasyWay control program. Featuring clearly presented screen masks, this control system is easy to use thanks to its intuitive operator guidance concept. WPS 3.2 EasyWay provides the operator with support during every stage of the grinding process - covering not only the spring input data, but also programming and monitoring of grinding cycles as well as grinding path control and sparking time. It also provides the electronic control elements for the down-feed grinding technique. High degree of automation thanks to automatic loading unit This feature requires an optional interface to be integrated into the machine. With the addition of the automatic loading unit, available as an option, the G 450 becomes a highly automated piece of equipment. The picture to the left shows an example of an automatic loading unit: This solution uses two buffer lines with three rows in each case to accommodate the loading plate, creating maximum availability. The associated handling robot simplifies the set-up process and ensures that operation is able to continue reliably. If the automatic loading unit is installed, there is also the option of equipping the machinery with a camera system for the reversing device on request, making it possible to align conical springs. The sorting unit is also available as an option. When it comes to operating the machinery system in climate zones exceeding 40 degrees, the options of an air conditioning unit as well as a compatible isolating transformer for voltage equalization are available as additions to the pair of fans installed as standard. Also available as an option, the automatic central grease lubrication system consistently increases availability by ensuring that lubrication is accurately and continuously maintained. Adding a teleservice connection also provides a rapid solution for keeping downtimes caused by machine problems to a minimum. Typical applications for the G 450 involve grinding valve and clutch springs in the automotive industry, but it can also be used in areas of mechanical engineering such as industrial and press springs (die springs). There are plans to unveil a version featuring two loading plates in the near future - allowing maximum production rates to reach as much as 5,000 to 6,000 springs per hour, depending on the spring geometry.
