Abstract

The invention discloses a simple micro-electric discharge machining (micro-EDM) / electrolytic machining main shaft. The simple micro-EDM) / electrolytic machining main shaft uses a BM320F electric main shaft produced by Nippon Seiko Kabushiki Kaisha (NSK) as a power source, the rotating speed can be continuously adjusted between 1000 r / min and 80000 r / min under the high rotating precision, and the wide micro-EDM) / electrolytic adjustable range and the high-speed rotating machining are realized; a priming support of the main shaft is made of an insulating PLA material through 3D printing, the integral printing forming of the complicated structure can be realized, and it is ensured that the whole main shaft is simple and compact in structure; and a power transmission device of the main shaft isof an integrated type insulating sleeve structure and can be assembled together with the electric main shaft and a tool electrode, and moreover, the power transmission device can be effectively insulated from the electric main shaft on the premise of ensuring the high transmission precision.

Description

technical field [0001] The invention relates to the technical field of micro special machining, in particular to a simple micro EDM / electrolytic machining spindle. Background technique [0002] Micro EDM (Electrical Discharge Machining, EDM) is also known as electrical discharge machining or electroerosion machining. The high temperature corrodes the metal material; the tool does not touch the workpiece during processing. This technology has been widely used in the micromachining of hard and difficult-to-machine materials such as cemented carbide, die steel, hardened steel, polycrystalline diamond, etc., and can also be used for micromachining of workpieces with low stiffness and complex surface shapes. [0003] Microelectrochemical machining (Microelectrochemical machining) refers to the processing method of electrolytic machining to obtain high-precision, small-sized parts within the range of micro-machining (1μm ~ 1mm), and has been widely used in cylindrical parts, spli...
