A numerically controlled grinding machine equipped with two registers in which data concerning the positions of the cylindrical and shoulder grinding surfaces of a grinding wheel is stored. A reference point is established on the wheel spindle stock. A reference member having two reference surfaces is disposed on the worktable. The machine further includes a manual pulse generator for moving the grinding wheel head and the worktable, detectors for detecting the distances traveled by the wheel head and the worktable, a data entry device, an arithmetic processing unit, and a memory.

Numerically controlled grinding machine

An operator's panel for a numerical controller of a grinding machine comprises a main frame of a generally box shape, which is carried on a front portion of a bed of the grinding machine for pivotal movement about a horizontal axis. A manual pulse generator for supplying the numerical controller with pulse signals is mounted in the main frame, and a manual feed handle is secured to an input shaft of the pulse generator. A mechanism is further provided for locking the main frame at such an angular position as desired by an operator of the grinding machine.
