Description

technical field

[0001] The invention belongs to the technical field of dressing superhard grinding wheels, and in particular relates to an optical curve grinding wheel used for dressing chamfering grinding wheels of metal bond superhard materials and a preparation method thereof. Background technique

[0002] Metal bond superhard material chamfering grinding wheel is mainly used for processing the edges and corners of metal, ceramics, glass and other materials. There are concentric arc micro-grooves distributed on the outer circle. schematic diagram see figure 1 and figure 2 ).

[0003] At present, there are mainly three ways of dressing the chamfering grinding wheel of this kind of metal bond superhard material, which are electrolytic grinding dressing, spark machine online dressing, and mechanical dressing. The device is on-line dressing, and the accuracy is seriously lost after disassembly, so it is impossible to carry out mass production of chamfering grinding wheels...
