Hard alloy hardness testing mainly uses Rockwell hardness tester to test HRA hardness value. The PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide. The weight accuracy of the instrument is the same as that of the desktop Rockwell hardness tester, and it is very convenient to use and carry. Cemented carbide is a kind of metal. The hardness test can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, structure and heat treatment process conditions......

The parts processed by cemented carbide cutting tools can obtain the required dimensional accuracy and surface quality, which is the most basic processing method in the machinery manufacturing industry. Cutting refers to the method of using tungsten steel cutting tools (carbide cutting tools) to remove the excess material of the processed parts. Cutting using tungsten steel cutting tools occupies an important position in the national economy. In the middle and late Spring and Autumn Period, there was the earliest surviving engineering work "Kaogongji"...

Diamond tools have extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. It can be used for precision processing of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high silicon aluminum alloys and other tough non-ferrous metal materials. There are many types of diamond tools with significant performance differences. The structure, preparation methods and application fields of different types of diamond tools are quite different.

According to statistics from the State Intellectual Property Office, as of March 2010, the number of patent applications received in my country has exceeded 6,011,448. However, among the numerous patent applications, domestic tool companies still lack the number of patent applications. If you enter the company name to search, the comparison results may be even more surprising. Many internationally renowned tool companies have applied for more than 100 patents, among which Sandvik Coromant has registered more than 400 patents.
