Grinder for medical devices - unattended two shift operation

Five axis CNC grinder has two workheads with special fixtures for long medical devices.  A custom designed stacking system for trays of parts allows unattended operation for two shifts.

Dual work fixtures for medical devices

Two workheads allow parts to load on one head, while grinding takes place on the other.  This reduces lost time for loading to one second.

Automatic wheel profiling is done with a rotary diamond dresser.  Dressing frequency is selected in a menu and the grinding program automatically compensates for size change.
