Abstract

The invention relates to an EDM milling method used for nonconductive materials, belonging to a mechanical machining field. When machining, a tool anode and a tool cathode are respectively connected with the anode and the cathode of an impulse powder supply. The tool anode and the tool cathode are provided with tubular structures and are arranged on the same shaft, and are separated by an insulation medium layer. A conductive liquid flows from the central hole of internal tool electrodes to the surface of the nonconductive material, and triggers discharge when flowing through the ends of the tool anode and the tool cathode, and then the nonconductive material can be corrosion-removed and machined by effects of high temperatures and high voltages generated by the discharge instantaneously. A main shaft head can drive the tool anode and the tool cathode to revolve and do a Z-direction movement. A nonconductive material work piece to be machined is arranged on X and Y movable work tables, and an EDM milling to the nonconductive material work piece with a complicated shape is realized by a linkage between the main shaft head and the work tables. The EDM milling method used for nonconductive materials of the invention has the advantages that machining efficiency is high, surface quality is high and the environment is not polluted, etc.

Description

technical field [0001] The invention belongs to the field of mechanical processing and relates to an electric spark milling method for non-conductive materials. Background technique [0002] At present, the electrical machining methods of non-conductive materials studied by scholars at home and abroad mainly include: electrolytic EDM composite machining, auxiliary electrode machining, high-voltage EDM and other methods. [0003] The research and development of EDM technology for non-conductive and difficult-to-machine materials is a research hotspot in the field of EDM technology. At present, scholars at home and abroad are mostly focusing on the electrolytic EDM composite machining technology for non-conductive and difficult-to-machine materials. This kind of machining technology uses the spark discharge in the electrolyte for machining. The positive pole connected to the pulse power supply, when the pulse voltage is applied between the two poles, bubbles will be generated...
