Abstract
The present invention is a device for contouring blocking burrs for a milling cutter. The penumatic broach or spindle is equipped with a tachometer, which controls the reversal of the supply of a pneumatic jack connecting the spindle to the wrist or handle of the robot as soon as the rotation speed of the cutter drops below a threshold value. The blocking burrs are then cut off by means of successive passes.
