WORKING DEVICE FOR THE BEARINGS OF A CRANKSHAFT OF A THERMAL ENGINE

摘要

The present invention relates to a machine for the machining of a metal block, especially for boring and facing. The machine according to the invention comprises a laser sighting system making it possible to bring the component to be machined into coincidence with an axis (X) or a reference plane (XY). This system makes it possible, by means of removable optoelectronic sensors, to obtain a control signal allowing the holding table to be positioned in an assisted manual way or automatically, for example with a numerical control.
