Hard alloy cutting tools have the following advantages:
1. High hardness and wear resistance: Hard alloy cutting tools have a high hardness, usually between HRA89-93, much higher than high-speed steel cutting tools. This enables it to maintain good sharpness during the cutting process, with excellent wear resistance and the ability to withstand high cutting forces and wear, greatly extending the service life of the tool. For example, when processing high hardness steel, the wear rate of hard alloy cutting tools is significantly slower than that of other materials, allowing for continuous and stable cutting.
2. Good heat resistance: It has good thermal hardness and can maintain high hardness and strength in high temperature environments. Generally speaking, hard alloy cutting tools can maintain good cutting performance even when the cutting temperature reaches 800-1000 ℃, which enables them to adapt to advanced machining processes such as high-speed cutting and dry cutting, and improve machining efficiency.
3. High compressive strength: Hard alloy has a high compressive strength of over 6000MPa, which can withstand large cutting pressures and is not easily deformed during the cutting process, ensuring the stability and accuracy of cutting.
4. Excellent cutting performance: High cutting efficiency, due to its high hardness, good wear resistance, and strong heat resistance, it can perform cutting at high cutting speeds and feed rates, thereby improving machining efficiency. At the same time, the machining accuracy is high, and the manufacturing accuracy of hard alloy cutting tools is high, which can ensure the accuracy and stability of machining dimensions. The machining surface quality is good, and lower surface roughness can be obtained, which helps to improve machining quality.
5. Wide applicability: It can process various materials and can be used to process various metal materials, including steel parts, cast iron parts, non-ferrous metals, and some difficult to process materials such as high-temperature alloys, titanium alloys, stainless steel, etc. And it is suitable for various processing methods, and can be made into various types of cutting tools, such as turning tools, milling cutters, drill bits, boring tools, etc. It is suitable for various processing techniques such as turning, milling, drilling, boring, etc.
