How to identify the hardness and wear resistance of cutting tools
Release time：
2022-08-22
Hardness is the basic property that cutting tool materials should have. For the cutting tool to cut chips from the workpiece, its hardness needs to be greater than that of the workpiece material. The chip edge hardness of the cutting tool used for chip metal is generally above 60hrc, and wear resistance is the ability of the material to resist wear. The higher the hardness of the hard points in the structure, the more the number, the smaller the particles, the more uniform the distribution, the better the wear resistance. Wear resistance is also related to the chemical composition, strength, microstructure and temperature of the friction zone of the material.

1. Sufficient strength and toughness
To make the cutting tool withstand high pressure and work under the shock and vibration conditions that often occur in the cutting process without chipping and breaking, the CNC tool material needs to have sufficient strength and toughness.
2. High heat resistance
Heat resistance is the main indicator to measure the cutting performance of cutting tool materials. The cutting tool material should also have the ability to be not easily oxidized at high temperature and have good anti-adhesion and anti-diffusion ability, that is, the material should have good chemical stability.
3. Good thermal physical properties and thermal shock resistance
The better the thermal conductivity of the cutting tool material, the easier the cutting heat will be dissipated from the cutting area, which is beneficial to reduce the cutting temperature.
The above is the method of identifying the hardness and wear resistance of cutting tools shared by Sol cutting tools, I hope it can help you!
