All machine components are controlled using the operator panel – irrespective of the series and the used control system. The identical structure, intuitive menu guidance and visualization of the workpiece geometry make for extreme user convenience and flexibility in operation. Programming takes place directly using the operator panel or an external programming tool. JUCAM Grinding camshafts with JUCAM With its JUCAM CBN non-circular grinding machines, JUNKER offers a multi-purpose solution for the complete machining of camshafts. And the JUCAM is also able to grind single cams. The type range covers all cam profiles: Cylindrical Concave/convex With/without chamfers With/without radius With tangent Polygon/elliptical Depending on the machining method and the required yield, platforms and grinding spindle head versions are individually configured and installed for the various JUCAM types. Pre- and finish grinding in one clamping JUCAM non-cylindrical grinding machines mean: grinding cams, bearings, ends, thrust bearing shoulders and camshaft adjustment elements in one clamping. The use of CBN grinding wheels permits both pre-grinding and precise finish grinding. Besides the automotive industry, these machines are also used in the textile and pump sector and for making cutting tools for deep-hole drills PURELY A MATTER OF FORM The non-cylindrical grinding machines of the JUCAM series impress with precise grinding results in a single clamping set-up. Thanks to the control system with learning function – with which virtually all disturbing variables are compensated – camshafts, cam pieces and individual cams are given a perfect finish. Decades of experience in grinding cams, in combination with the many special solutions and a wealth of expertise, have convinced engine and pump manufacturers worldwide. CAM Grinding Grinding machines for grinding camshafts, cam pieces and individual cams combine non-cylindrical grinding for the cams and cylindrical grinding for the bearings. With non-cylindrical grinding, the grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis). CBN or diamond are used as an abrasive – for high cutting performance with a constant level of quality and a long tool life. The cam geometry is specified in a elevation table. In the process, each angle is assigned an elevation value to define the cam contour and import it to the program. The software then interpolates the values automatically. The cam contour is frequently concave in the infeed and discharge area. Here, the concave radius determines the maximum grinding wheel diameter that can be used. ECONOMICAL GRINDING WITH LEADING TECHNOLOGY WORKPIECE SPECTRUM The grinding machines of the JUCAM series grind camshafts, cam pieces and individual cams in all series production sizes. In addition to the cams, the bearings and the flat shoulders can also be ground in a single clamping set-up. Decades of experience in grinding with CBN guarantees maximum accuracy with extremely short cycle times The grinding range covers all cam shapes – with or without a chamfer or radius: • cylindrical/conical • concave/convex • polygonal/elliptical • with tangent Highlights • Broad range of grinding solutions for camshafts, cam pieces and individual cams • High utility value through adjustment to r espective grinding assignment • High long-term precision due to hydr ostatic round guides • Maximum repeat accuracy thanks to CBN or diamond abrasives • Minimized undulations due to grinding wheel balancing on two levels HIGHLIGHTS AND SPECIAL SOLUTIONS When grinding cam pieces, it is essential that the exact angular reference to the inner toothing is ensured. For this reason, the JUCAM clamps the cam pieces with an inner clamping mandrel. The longitudinal and radial positioning and the C-axis with direct drive result in a smooth, transition-free shifting surface. CAM PIECES The workhead with two opposing clamping devices minimizes the downtime when grinding individual cams and cam pieces: While grinding is being carried out on one side, loading and unloading, clamping and positioning are carried out on the other. The only downtime: Swiveling by 180 degrees in less than 3 seconds. DOUBLE WORKHEAD The use of set grinding wheels is ideal for grinding cams with the same orientation. Several cam contours are ground simultaneously in one operation, which considerably reduces the cycle time. SET GRINDING WHEELS FIELDS OF COMPETENCE The JUNKER Technology Centers in Nordrach, Germany and in Holice, Czech Republic offer a wide selection of grinding machines for demonstrations and customer-specific grinding tests. These facilities give potential buyers and customers the chance to be impressed by the technical and economic performance of JUNKER and ZEMA grinding machines and test them on their own workpieces. TECHNOLOGY CENTERS The company group‘s growing sales and servicing network ensures satisfied customers worldwide. JUNKER Premium Service acts swiftly and with outstanding expertise wherever its customers are around the globe. Available around the clock, this service provides the assurance of planning security for customers: The highly qualified team will find the right solution no matter what the problem. SERVICE The key indicator for the efficiency of a machine tool is the energy requirement for each good part produced. Through the use of JUNKER grinding machines, this value is continuously dropping. As the number of grinding steps possible in a single machine increases, machine downtimes diminish and precision improves. The company‘s energy management program continues to uncover and leverage added potential for savings. Examples include frequency-regulated components, recovered braking energy or optimized sealing air consumption in our own internally developed grinding spindles. ENERGY EFFICIENCY JUNKER is able to provide comprehensive references for the design and implementation of production lines ideally tailored to the specific requirements of its customers. As a general contractor, JUNKER places added importance on standardized interfaces such as workpiece transport, coolant systems or measuring devices. This enhances efficiency and ensures the long-term interaction of all the different components of a production line. PRODUCTION LINES A new grinding technology challenge for JUNKER? „Tell us what your grinding challenge is and we‘ll supply you with the perfect machine.“ The engineers and technicians of the JUNKER team are able to draw on an enormous fund of technological expertise to provide customized solutions for every field of application.
