Abstract

The present invention discloses numerically controlled electric spark machining apparatus and process for great depth / diameter ratio toothed female die. The horizontal machining apparatus includes onebiaxial numerically controlling device, two servo motors, one tool electrode, one fixture with three claws, one rotary inner sleeve for workpiece, one local directional liquid leading unit and one tool electrode holding casing. The present invention has combination of electric spark generating technology and numerically controlling technology to expand the machining range, and is especially suitable for machining hard-to-machine materials.

Description

Technical field [0001] The invention belongs to the field of mechanical engineering powder metallurgy mold manufacturing, and in particular relates to a large-depth-diameter ratio tooth profile female mold numerical control electric spark generation processing device and a processing method thereof. Background technique [0002] For the rough machining of the internal tooth profile, the traditional machining method is gear shaping. However, due to the discontinuous working process, the efficiency is low; and the hardness of the gear shaper must be greater than that of the workpiece; the uniformity of the tooth profile depends on the working accuracy of the indexing mechanism; for the tooth profile female mold made of cemented carbide , The gear shaping method cannot be processed. In terms of internal tooth profile finishing: more tooth grinding methods are used, but due to structural limitations, it is not easy to implement. [0003] Non-traditional special processing: the use of...
