DEVICE FOR ORIENTING THE GUIDING HEAD OF AN ELECTRO-EROSION CUTTING MACHINE

摘要

A guiding head (23) of a wire-electrode (2) of an electro-erosion cutting machine comprises a nozzle generating a fluid jet which is coaxial to the wire (2). This head (23) is carried by a tray (32) pivoted by means of a universal joint (33) to the lower tray (25) of a crossmove table (24, 25). During the lateral moves of the tray (25), the head (23) takes a given inclination due to the co-operation between a finger (37) integral with the tray (32) and a ramp (38) integral with the tray (24) so that the head (23) remains coaxial to the wire (2) which is guided at its lower part by a fixed guide (not illustrated).
