CNC tool compared with the general machine tools used, there are many different requirements, mainly has the following characteristics:
⑴ rigidity (especially roughing tool), high precision, vibration and thermal deformation;
⑵ interchangeability for quick tool change;
High ⑶ life, cutting stable and reliable;
⑷ easy to adjust the size of the tool to reduce the tool change time to adjust;
⑸ tool should be able to reliably roll off the crumbs or dust, to facilitate chip exclusion;
⑹ serialization, standardization, in order to facilitate programming and tool management.
