Electrolyzer for use in electrolytic in-process dressing metallic bond pellet grinding processing

Abstract

The invention discloses an electrolyzer for use in electrolytic in-process dressing metallic bond pellet grinding processing, which belongs to the field of grinding precision processing. A grinding disk of which the upper surface is embedded with grinding pellets is taken as an anode, and is driven to rotate by a machine tool main shaft; a workpiece disk and a workpiece are arranged in a chuck; a pressure head is used for driving the chuck to move transversely in a reciprocating way on the grinding disk to grind the workpiece; stainless steel boxes are taken as cathodes and are symmetrically distributed on both sides of the pressure head, and a micro transmission mechanism is arranged to realize fine adjustment of upward and downward displacement of the stainless steel boxes; through sensors, a PLC (Programmable Logic Controller), stepping motors and the micro transmission mechanism, the distances between the bottoms of the stainless steel boxes and the grinding disk are always kept about 1 millimeter; and moreover, the bottom surfaces of the stainless steel boxes are provided with grinding liquid spray holes which are distributed uniformly, so that an interpolar electrolytic in-process dressing function, i.e. anode dissolving, is performed fully and stably, and ultra-precision grinding processing of the workpiece is realized.

Description

technical field [0001] The invention discloses an electrolytic device for on-line electrolytic sharpening metal bond pill grinding processing, which belongs to the field of precision grinding processing. Background technique [0002] On-line Electrolytic Dressing Wheel (ELID) precision mirror grinding is a new grinding technology developed from Japan at the end of the 20th century. It has opened up a new way of precision ultra-precision mirror grinding, and has important applications in ultra-precision mirror processing of difficult-to-machine materials such as high-temperature alloys and brittle hard materials. There are problems such as large grinding force, high temperature, low efficiency, and difficulty in sharpening. Many scholars at home and abroad have conducted in-depth research on its process system and processing mechanism. At present, ELID mirror grinding technology has gradually realized its industrialization in optical lens, optical glass, semiconductor micro...

AI Technical Summary

Problems solved by technology

However, the research on ELID grinding technology has not attracted more attention, and grinding is an important precision and ultra-precision processing technology, which is almost suitable for the processing of various materials, and the traditional grinding technology is suitable for brittle, hard and difficult-to-machine materials. During processing, there are problems such as unstable processing accuracy, high processing cost, low efficiency, and difficult grinding tool dressing, which makes it difficult to meet the processing requirements of high precision and high efficiency.

Therefore, combining ELID grinding technology and grinding technology to solve the problems existing in traditional grinding processing methods is the key to expanding the field of grinding, and the electrolytic device used for online electrolytic sharpening metal bond pellet grinding processing is ELID grinding technology The core of the core, its related patents and references have not yet been consulted
