一、基本原理刀具的刃磨质量对刀具的耐用度和加工质量影响很大。刀具刃磨时,除根据被加工对象和刀具本身的特点合理刃磨几何角度及有关参数外,刃磨中应降低磨削温度,避免因磨削烧伤而导致刀具刃部切削性能的降低,同时提高刀具前刀面和后刀面的刃磨光洁度不仅能提高刀具的耐磨性而且能相应提高被加工工件的表面光洁度。刀具刃磨时采用在磁场中磨削的方法,正是利用了磁场对刀具材料(铁磁性村料)的磁致伸缩和热磁效应,能降低磨削温度,并且在光磨时由于微粉碎在磁场作用下, First, the basic principle Tool sharpening quality of the tool durability and processing quality great influence. Tool sharpening, in addition to the geometry of the object to be machined and the characteristics of the tool itself geometry and related parameters, the sharpening should reduce the grinding temperature, to avoid cutting burns caused by cutting edge cutting performance reduction, at the same time Raising the sharpening finish of the rake face and flank face of the tool not only enhances the wear resistance of the tool but also increases the surface finish of the workpiece being machined. Tool sharpening grinding method used in the magnetic field, it is the use of the magnetic field on the tool material (ferromagnetic material) magnetostrictive and thermal magnetic effect, can reduce the grinding temperature, and grinding in the light due to grinding Under the action of magnetic field,
