machining center Planetary lapping machine for PCD and CVD Coborn’s planetary lapping machines are designed to polish the top surface of PCD discs to a flat, mirror finish The PL5 is equipped with 6 work heads as standard Coborn’s planetary lapping machines are designed to polish the top surface of PCD discs to a flat, mirror finish. They can also be used to polish CVD discs and PcBN. They consists of a number of independent work heads which hold the discs against a large, horizontally mounted planetary motion grinding wheel. tains the disc at a uniform temperature to minimise disc dishing. The PL5 is equipped with 6 work heads as standard. Each arm is fitted with a double gimbal fixture to allow the disc to self-level. The disc holders are motor-driven. The lapping pressure can be individually adjusted. The lapping or polishing of the top surface of PCD or CVD components is desirable to produce a smooth surface for chip flow and a good cutting edge for geometric integrity. It also maximises edge life, enhancing the characteristics of PCD and also minimises surface deviations over a large PCD or CVD area. The benchmark for the diamond industry The RG9A is a fully automatic, high-precision grinding machine designed to meet the sophisticated demands of toolmakers working with hard and ultra-hard materials, such as PCD, PcBN, carbides and ceramics. This versatile machine is supplied “robot ready” and the optional Stäubli 6-axis robot can be added to the RG9A to facilitate fully autonomous “lights out” production of tools. The RG9A software is user-friendly where straightforward programming blocks can be built step-by-step to produce the tool forms and geometries you need. From simple, single point shank tools to helical/radius multi-point rotary tools, the RG9A has all the capabilities needed to minimise tool production costs. The RG9A is a fully automatic, high-precision grinding machine It is impossible to use flood cooling when polishing large areas of PCD as the discs ‘aqua-plane’ on the wheel surface. Therefore, the lapping is a dry process and the wheel is internally cooled using water from an associated water chiller. Chilled water is also fed to the back of each disc.

machining center The new productive STUDER machine S36 Due to the rapid development of e-mobility and other alternative drive types, among other things, the demand for suitable grinding machines for a new variety of components in vehicle manufacture is also increasing. That is why STUDER has developed the new S36. It will be positioned between the compact S11 for small workpieces and the S22 for medium-sized workpieces. Many features of the new S36 are similar to its very successful predecessor, which sold over a thousand units. New functionalities for changing requirements supplement proven concepts. “The demand for cost-effective grinding solutions for medium to large series also remains consistently high in e-mobility applications”, says project manager Martin Habegger. In addition to vehicle manufacture the new machine will also be used in the hydraulic, pump and toolmaking sectors. The S36 has a fixed grinding head with grinding wheel angles of 0,° 15° or 30° available. The distance between centers is 650 mm and the maximum workpiece weight is 150 kg. Proven components have been used in the machine. These include a Granitan® machine bed and a workhead with high-precision roller bearings. Range of parts / market segment The machine concept is designed for productive external grinding of chuck and shaft components. STUDER serves many different industries with the S36. Its field of application extends from die and mold through the aerospace industry to the production of parts for the hydraulic and automotive industry. Grinding head of the new STUDER S36 production cylindrical grinding machine State-of-the-art grinding technology for optimum price/performance An outstanding feature of the new machine is its large grinding wheel, which has a Ø 610 mm and initially a maximum width of 125 mm. This makes the S36 above standard in its category. In addition, the machine comes with C.O.R.E. OS, the UNITED GRINDING Group’s smart, cross-brand operating system – including touch panel and intuitive operation. Thanks to the uniform C.O.R.E. software architecture, data exchange between the machines is easily possible. This is also possible with thirdparty systems via the integrated umati interface. This interface also provides access to the UNITED GRINDING Digital Solutions products directly at the machine and without the installation of additional hardware. C.O.R.E. creates the technical foundation not just for these and other IoT and data applications, but also for a revolutionary, standard and simple mode of operation. The newly developed SmartJet® nozzles for efficient and automatic coolant supply are fitted as standard. Thanks to these cooling is now managed by the machine control. A frequency-controlled pump and a dynamic pressure measuring unit are used as central components. These allow to precisely adjust the volume flow to suit the process – for rough grinding, fine grinding or finishing. The cooling medium is fed to the grinding wheel via manifold and flow-optimized, adjustable nozzles. “This concept guarantees precise, efficient and reproducible cooling”, emphasizes Martin Habegger. “We offer customers the S36 with all of this modern grinding technology at an excellent price/performance ratio”, says Habegger.
