Five-Axis CNC Grinder Extends X-, Y-Axis Movement

Schütte’s 325linear five-axis CNC grinder offers extended X- and Y-axis movement plus two auxiliary slides for improved grinding wheel guidance over the entire machining envelope. The second additional auxiliary slide enables the use of tool guidance, part support, tailstock or workpiece pallets.

The grinder's universal rotation A axis offers high concentricity with less than 0.0001-degree resolution and pitch accuracy while the X-, Y- and Z-axis resolution is less than 0.1 microns. The A axis can be equipped with collet chucks, hydraulic expansion chucks or multi-range chucks. The A-axis configuration also enables position-oriented clamping of non-rotationally symmetrical workpieces so that sequential workpieces with various roughing and finishing requirements can be preset for continuous processing. The swiveling C axis for the grinding head has a 225-degree range of motion with less than 0.0001-degree resolution accuracy.

The primary motor spindle enables speed ranging to 12,000 rpm with 15 kW of maximum drive output, while the grinding spindle ranges to 24,000 rpm. X-, Y- and Z-axis travels measure 480 × 250 × 275 mm. The grinder is equipped with a Siemens 840D sl CNC with compatible drive technology and features Schütte Integrated Grinding Software (SIGSpro) as its programming interface. The grinding system offers scalable automation with a 140-position toolchanger, five to 24 grinding wheel magazine, and a flexible robotic tool gripper as options.
