Bed main shaft and each feed shaft be to be designed for electro-discharge machining situation, it is difficult to resist the cutting force of grinding, generally size,
Structure, installation way etc. are unsuitable for grinding.
2. the abrasive dust electric discharge lathe easy to pollute that grinding generates, especially pollution electric discharge liquid；
3. the Mars that grinding generates easily causes safety accident on electric discharge lathe；
4. simply applying common method for grinding on electric discharge lathe, then structure is complicated, and electric discharge platen holds
Larger-size grinding attachment under not, it is also possible to be difficult to bear its weight.
Electrode preparation is one of electric machining field key technology with amendment, and electric machining especially precise high-efficiency electric machining needs
The correction technique of precise high-efficiency.Therefore, needing one kind overcomes the anti-roasting method of block electrode with grinding law limitation and with above two
