The correct selection and use of tool systems often determines the tool life, cutting rigidity, and processing efficiency, and plays a decisive role in product quality and 

processing efficiency in metal cutting. Modern metal cutting requires the use of tool systems:

1. It has high accuracy, positioning accuracy and reliability;

2. Sufficient rigidity: CNC machining is often in a strong cutting state, so the tool must have high enough rigidity;

3. Requirements for convenient loading, unloading and adjustment: tool changing is quick and safe;

4. Suitable for high-speed cutting: has good dynamic balance and small moment of inertia;

5. Facilitate cooling: fully cool the processed area and the processed tool during the processing process to improve tool life and product processing accuracy;

6. Requirements for standardization, generalization, and serialization: It facilitates tool clamping, simplifies the structural design of the manipulator, reduces tool 

manufacturing costs, reduces quantity, and facilitates CNC programming and tool management.

In modern metal cutting, with the application of high-speed, high-precision, high-intensity cutting and digital processing, commonly used tool systems include thermal 

expansion tool holders, hydraulic tool holders, spring chuck tool holders, strong clamping tool holders, etc. Here are some taboos on the use of these tool handles.
