Abstract

The invention discloses a hard crisp free-form surface grinding device. The hard crisp free-form surface grinding device comprises ELID grinding equipment used for grinding to a workpiece surface anda laser device used for heating to the workpiece surface. The ELID grinding equipment comprises a grinding wheel used for grinding to the workpiece surface, in the grinding direction, ahot spot formedby laser emitted by the laser device on the workpiece surface is located in front of a grinding point formed by the grinding wheel on the workpiece surface. The machining accuracy is improved by using the ELID grinding equipment, the grinding difficulty is reduced by using the heating way of the laser device, the grinding efficiency is improved, and the service life of the grinding wheel is prolonged.

Description

technical field [0001] The invention relates to the field of curved surface processing, in particular to a hard and brittle free curved surface grinding device and a grinding method. Background technique [0002] With the development of optoelectronic technology, IT industry and digital industry, free optical curved surface parts have become the core components of optoelectronic and communication products. In order for the optical system to have excellent optical performance, its optical surface mold core must often reach a nano-scale mirror surface, and its material is often made of high-speed tool steel, hard alloy steel or even ceramic materials. [0003] For the ultra-precision machining of hard, brittle and difficult-to-machine materials, ELID (Electrolytic In-Process Dressing) grinding technology realizes online electrolytic dressing of ultra-hard micro-powder grinding wheels, and is widely used in the grinding of hard and brittle materials and other difficult-to-machi...
