Fritz Studer Internal cylindrical grinding of dies, complex workpieces
Switzerland – Fritz Studer has introduced three new radius internal cylindrical grinding machines.
According to the company, the main fields of application of the new S121, S131 and S141 grinding machines are the manufacture of dies, especially in the packaging industry, where tungsten carbide and ceramic are primarily processed, and the production of hydraulic components such as axial pump pistons, guide plates and housings made of hardened steel, cast iron and copper.
Other fields are the production of complex workpieces with several tapers from 20° to 90° in a single clamping, such as in the watch and medical industries, which also use very hard materials, as well as the manufacture of human implants for shoulders, knees and hips made of ceramic and titanium, Studer says.
The swing diameters for the S121, S131 and S141 are 250, 300 and 400 mm, respectively. The maximum length of parts including the clamping device is 300 mm for all three machines with a maximum workpiece weight (with clamping device) of 100 kg. Furthermore, all three machines use the Studer SIM operating system, which is said to provide a stable programming environment.
