The tool material for precision machining refers to the material of the cutting part of the tool. When performing metal cutting, the cutting part of the tool is in direct contact with the workpiece and cutting element, bearing a large cutting pressure and impact force, and generating severe friction with the workpiece and cutting element, resulting in an increase in cutting temperature. This means that the cutting part of the tool is working under harsh conditions of high temperature, high pressure, and intense friction, and mastering the basic properties that tool materials should possess. Suzhou Pudson Precision Manufacturing Co., Ltd. is a high-quality processing enterprise that integrates precision machinery design and production, committed to providing customers with excellent precision machining services.

So what are the basic properties that cutting tool materials should have?

1. High hardness. The hardness of the tool material must be higher than that of the workpiece material being processed. Otherwise, under high temperature and pressure, the sharp geometric shape of the tool cannot be maintained, which is a basic property that tool materials should possess.

2. Sufficient strength and toughness. The material of the cutting part of the tool must withstand significant cutting and impact forces during cutting.

3. High wear resistance and heat resistance. The wear resistance of tool materials refers to their ability to resist wear and tear. Generally speaking, the higher the hardness of the tool material, the better its wear resistance. The wear resistance of tool materials is also related to the metallographic structure. The more carbides there are in the metallographic structure, the finer the particles, the more uniform the analysis, and the higher the wear resistance.

4. Good thermal conductivity. Cutting tool materials with good thermal conductivity can enhance their resistance to thermal shock and cracking, which is particularly important for intermittent cutting using brittle tool materials, especially when machining workpieces with poor thermal conductivity.

5. Good craftsmanship. For ease of manufacturing, it is required that the tool material has good precision machining performance for parts, including forging, welding, cutting, heat treatment, and grindability.

6. Better economy. Economy is one of the main indicators for evaluating new tool materials, and it is also one of the main foundations for correctly selecting tool materials and reducing product costs.

7. Anti adhesion and chemical stability.

The above points are the properties that precision machining tool materials should possess. The selection of tools, especially when machining more precise parts, requires strict requirements for the tools in order to meet the machining requirements and fully utilize the benefits of CNC lathes.
