United Grinding North America will be featuring the Studer S131r cylindrical ID-radius grinding machine for the toughest ID grinding operations where maximum precision is paramount.

The Studer S131r excels 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˚.

The machine’s fully automatic, completely sealed, simultaneously swiveling direct-drive B-axis offers superior thermal stability, mechanical rigidity and interpolation from -60˚ to +91˚, while the workhead C-axis enables form and thread grinding. High-precision axis drives with linear motors add speed and accuracy, and a -50˚ to +280˚ swiveling spindle turret with up to four grinding spindles enhances grinding flexibility. Temperature-stabilized components maintain precision while a Granitan® S103 mineral casting machine bed provides thorough vibration damping.

With a swing diameter of 300 mm (11.81”) above the table, 350 mm (13.78”) X-axis/cross slide travel, and 400 mm (15.75”) Z-axis/longitudinal slide travel, the S131r can machine external diameters up to 160 mm (6.3”) with an external grinding wheel 250 mm (9.84”) in diameter. The S131r accommodates parts up to 300 mm (11.81”) long and up to 100 kg (220 pounds), including clamping devices.

StuderSIM software enables operators to machine complex parts, often in a single clamping. StuderSIM derives workpiece geometry from a drawing, completely defining and generating all the data required for grinding cycles. Furthermore, operators can simulate grinding to easily check and visualize the processes on a PC or on the machine itself.

The S131r also features high-precision axis drives with linear motors, a Granitan® machine bed for high levels of damping, thermal stability and guidance accuracy, and the StuderGuide® guideway and linear drive system for high wear resistance and long working life.

United Grinding will feature the Studer S131r at Booth #236802.
