The Studer S131r can tackle both general grinding applications and the production of complex workpieces made from very hard materials. It is also suited for hydraulic components such as axial pump pistons, guide plates and housings made 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°. Additionally, 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-cast machine bed provides vibration damping.
The S131r can machine external diameters up to 160 mm (6.3 inches) with an external grinding wheel 250 mm (9.84 inches) in diameter. The S131r accommodates parts up to 300 mm (11.81 inches) long and as heavy as 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.
Check out the S131r at booth 236802 in the North Building.
