A good horse needs to be equipped with a good saddle and uses advanced CNC processing equipment. Choose the right tool material, the tool life,Processing efficiency, processing quality and processing cost have a great impact. Tool materials should have the following basic properties:

The choice of tool material has a great influence on tool life, processing efficiency, processing quality and processing cost. The tool must withstand high pressure, high temperature, friction,

Shock and vibration. Therefore, the tool material should have the following basic properties:

(1) Hardness and wear resistance. The hardness of the tool material must be higher than the hardness of the workpiece material, which is generally required to be above 60HRC. The higher the hardness of the tool material, the better the wear resistance.

(2) Strength and toughness. Tool materials should have high strength and toughness in order to withstand cutting forces, impacts and vibrations, to prevent tool brittle fracture and chipping.

(3) Heat resistance. The tool material has better heat resistance, can withstand high cutting temperatures, and has good oxidation resistance.

(4) Process performance and economy. Tool materials should have good forging performance, heat treatment performance, welding performance; grinding processing performance, etc., and should pursue a high performance-price ratio.
