About Studer S131r Internal Grinder

The Studer S131 R is a radius internal cylindrical grinding machine that is especially suitable for grinding complex work pieces from very hard materials. It is the ideal machine for internal, face and external grinding of chuck components. The machines are also well suited for the production of complex work pieces with several tapers greater than 20 degrees to 90 degrees in a single clamping. With a work head on a newly swiveling B-axis, the used S131 radius grinding machines offer greater thermal stability, mechanical rigidity and interpolation from -60 degrees to +90 degrees. In the S131 machine, the cross slide comes with a four position turret with direct drive. The spindle on the radius grinding machine is arranged at the rear of the turret. The machines are also equipped with a dressing spindle or a fixed dresser on the B-axis and a measuring probe on the grinding head. Equipped with high precision axis drives with linear motors, extremely fast direct drive of the grinding spindle turret, automatic swiveling of the work piece table. The Studer radius internal cylindrical grinding machines are powered by Studer SIM software that enables an operator to machine complex parts. The main applications are in the watch and medical industries with extra-hard materials such as industrial ceramic, sapphire and tungsten carbide, as well as the manufacture of human implants for shoulders, knees and hips from ceramic and titanium.
