ABSTRACT:
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.
