1. Good rigidity (especially for rough machining tools), high accuracy, low vibration resistance and thermal deformation;

2. Good interchangeability, the durability, geometric shape, and dimensional accuracy of cutting tools of the same variety and specification are basically consistent, making it easy to quickly change tools;

3. High lifespan, stable and reliable cutting performance;

4. The size of the cutting tool is easy to adjust to reduce the time for tool replacement and adjustment; The adjustment and clamping of cutting tools should be simple and convenient.

5. The cutting tool should be able to reliably break or roll chips to facilitate the removal of chips;

6. Have a comprehensive modular tool system;

7. Serialization and standardization to facilitate programming and tool management.
