The abrasive machining and processing for material of diamond, crystal and metal glass are studied. Based on some technical investigations, an intelligent abrasive machining device which is controlled synchronously in X-Y-Z axis by single chip processor is developed. The device consists of central processing server and some local intelligent abrasive machining control devices which are controlled with distributed system linked by RS-485 serial bus. The device which has been put into practical application solves the problem of automatic switching and data transfering from CAD designing to NC instructions.
