Parts processed by cemented carbide cutting tools can obtain requirements of dimensional accuracy and surface quality. Cutting is a method of use of cemented carbide cutting tools to remove the excess material of the parts to be processed. Cutting using cemented carbide cutting tools plays an important role in the national economy.

China's cutting technology development facts

Ancient China's cutting has glorious achievements. Years of the Bronze Age in 2000 BC had metal cutting bud. Bronze knives, saws, filing was similar to the modern tools.

AD 1668 (Ming Dynasty) processing a 2m diameter astronomical instruments copper ring of its outside diameter bore, plane and scale accuracy and surface roughness have reached a very high level. As shown, it was using animal power to drive milling cutters for milling and to grind with millstone at that time. The cutters have similar modern veneer mill, the blade blunt shown foot sharpening machine sharpening.

In the long-term production practice, the ancients have to pay attention to summing up the experience of the use of cemented carbide cutting tools. Written by the Ming Dynasty Zhangzilie "orthography pass" seen, the ancients have put great emphasis on the role of the cutting edge, properly clarify the cutting edge of Lee Kennedy. The cutting principle has been plain exposition of dialectical materialism.

In recent history, China's machinery industry is very backward. According to statistics, only until the 1915 Shanghai Rongchangtai machine factory produced domestic first lathe, more than three thousand civil Machinery Industries in 1947, with more than 20,000 machines. Then use the tool steel cutter, cutting speed is very low.

Since the founding of New China, cutting technology has developed rapidly. Cemented carbide (cemented carbide cutting tools) are widely used in the 1950s to promote high-speed cutting, heavy cutting, multi-blade cutting, the rise of the upsurge of the reform of cemented carbide cutting tools. Relevant units continue to produce a new type of cutting tool materials, such as high-productivity, high-speed steel, high speed steel powder coated tool materials, composite ceramic super hard cutting tool materials, and so on.

21st century using carbide cutting tool materials more widely and continuously improve the technical performance of the traditional high-speed steel, cemented carbide materials. Super hard materials, such as cutting ceramic, polycrystalline cubic boron nitride, polycrystalline diamond cutting tool have got more applications. Coating of chemical and physical coating technology continues to evolve, new composite coating material with each passing day. Variety of today's cutting tool materials, in addition to the traditional metal materials, an increasing number of non-metallic materials. From soft rubber, plastic to hard granite stone, from ordinary steel to high-strength steel, titanium, chilled cast iron, hardened steel 70HRC about thermal spray and other hard materials.
