Abstract

A machine for grinding toothed cutting tools comprises an emitter capable of emitting a light or an ultrasound ray and an optoelectronic or an ultrasound receiver respectively. The receiver is associated with a circuit for controlling the movement of a table of the machine on which a tool to be ground is supported. The positioning of the table is effected by the interception of the light or sound ray by the teeth of the tool, which causes the receiver to act to stop movement of the table.
