RFS/RT/NT | The peripheral grinding machine achieves surface and/or chamfer grinding on circular knives, saw blades and circular blanks using the pendulum or plunge-cut method. Thanks to an additional grinding axis, subsequent grindings can be processed in one clamping. For example, the surface of the workpiece can be ground flat and a bevel machined onto the cutting edge in one work cycle.

The circular blade is held in the rotating workpiece holder by mechanical clamping devices, permanent magnets or electromagnets.The workpiece fixture is mounted on a rotary table that can be continuously adjusted from -10° to 60° so that a wider range of bevels can be machined onto the circular knife. After each dressing cycle, the traverse paths are automatically compensated and adapted to the pre-set peripheral speed.

The workpiece and grinding wheel are changed fully automatically by a handling robot. The robot can be equipped with a specially designed dual gripper so that it can pick up both the circular blade and the grinding wheel.

Thanks to the robot automation, the setup or changeover time is reduced from 30 minutes with manual loading and unloading to 3 minutes.
