United Grinding offers a full 360-degree range of Studer internal cylindrical grinding machines. This machine portfolio includes several universal-type models as well as those designed for high production and for radii grinding operations.

The range includes models for workpieces up to 1300 mm long and weighing as much as 250 kg. Some models are well-suited for internal, surface and external grinding of chuck components, while others handle all other conceivable internal cylindrical grinding applications. The machines deliver the highest precision and efficiency, especially for flange parts, spindle shafts, spindle housings, rotor shafts, bushings and more.

Three models specialize in high-precision internal cylindrical grinding of radii, spheres, balls, cones and diameters. Applications include the manufacture of die plates from carbide and ceramic as well as the production of hydraulic components such as axial pump pistons, guide plates and housings from hardened steel, cast iron and copper. These machines are also well-suited for workpieces made from industrial ceramic, sapphire and carbide materials frequently used in the manufacture of human surgical implants.

StuderSIM software supports the automatic direct drive B-axes and enables the machines to interpolate for high-precision radii grinding. The operating system enables programming of all basic cycles for grinding, dressing and process-supporting measurement. This type of programming guarantees high flexibility together with maximum user-friendliness. After programming, the process can be simulated and optimized to ensure reliability, as well as shorten programming times and boost cost effectiveness.

For simplifying other complex internal cylindrical grinding operations, StuderWIN software enables the full integration of in-process gauging and sensor technology for process monitoring, including contact detection and automatic balancing systems within the operator interface for standardized programming across different systems.
