Abstract:With the development of the modern manufacturing technology, the demands on the species of special tool and knifeedge are increasing. However, the complicated tools are very difficult to process by normal tool grinder and traditional production process. In view of this situation, a kind of fiveaxis CNC tool grinder was developed. The grinder was able to grind high hardness and complex tools like ball mills and so on, In addition,all precision work could be finished in a single setup.
