The accurate processing of metal work piece plane mostly adopts abrasive machining technology in present, which has been mature processing ways and is used mostly in mechanical industry. However, the consume of emery wheel is unavoidable in the abrasive machining technology. In order to avoid the abrasive burning, the continuous supply of coolant is necessary. In the addition, it is the unsoluted difficulty until now that the paste and block of emery wheel make it difficult to continue in grinding nonferrou...
