Studer’s S131r cylindrical ID-radius grinding machine is well suited for the toughest ID grinding operations where maximum precision is paramount. The Studer S131r is said to excel in general grinding applications and the production of complex workpieces made from extremely hard materials, along with hydraulic components such as axial pump pistons, guide plates and housings from hardened steel, cast iron and copper. The machine also handles single-clamping production of complex workpieces with tapers between 20 and 90 degrees.

The machine’s fully automatic, completely sealed, simultaneously swivelling direct-drive, B-axis is said to offer distinctive thermal stability, mechanical rigidity and interpolation from -60 to +91 degrees, while the work head C-axis enables form and thread grinding. High-precision axis drives with linear motors add speed and accuracy, the company says, and a -50 to +280-degree swivelling spindle turret with up to four grinding spindles enhances grinding flexibility. StuderSIM software enables operators to machine complex parts, often in a single clamping.

With a swing diameter of 300mm above the table, a 35mm X-axis/cross slide travel and a 400mm Z-axis/longitudinal slide travel, the S131r is said to machine external diameters of up to 160mm with an external grinding wheel of 250mm in diameter. The S131r accommodates parts up to 300mm long and up to 100kg, including the clamping devices.

One key feature is the wheel head with different wheel configuration options, and the possibility for an infinite B-axis. Also, an infinite B-axis enables users to control the wheel swivel down to 1/10 000ths of a single degree, so that a single wheel can be used for multiple angles and features on a single part.
