Abstract
A multi-head electro-discharging machine, in which each head member has an independent transmission assembly; the head member can move in X-axis, Y-axis and Z-axis directions by a guide screw rod; every head member can be adjusted independently for operation without intervening the others; every head member may be mounted with an electrode connector, and two head members can be operated simultaneously in a crossing manner; a plurality of head members are mounted along the rear side of a supporting frame of the machine, and one or more than one head members may be mounted on both ends of the supporting frame for further multi-processing operation.
Claims2
An electro-discharge machining apparatus, comprising a frame (1);
- a work support means (2) on said frame;
- first and second parallel horizontal guide rails (11 and 12) offset from each other on said frame alongside the work support means, said rails defining an X axis adjustment direction for the apparatus;
- a first base (40) slidably mounted on said first guide rail for adjustment along the X axis;
- a second base (70) slidably mounted on said second guide rail for adjustment along the X axis;
- a separate horizontal screw means arranged between the frame and each base, each said screw means being offset from the other whereby each base can be independently adjusted along its associated guide rail;
- a sliding block (32 or 62) motion along a Y axis transverse to the associated rail, a second separate horizontal screw means carried by each base for independent adjustment of the associated sliding block along the Y axis;
- a separate electrode support head (3 or 6) slidably mounted on each sliding block for linear vertical motion along a Z axis normal to the associated Y axis;
- and a third separate vertical screw means (33 or 63) carried by each sliding block for independent adjustment of the associated electrode support head along the Z axis.
