Lift the cutting tool , we may very strange, or even ignorant . I also occasionally encountered curiosity that I approached it , to understand some of its features . Here to introduce it to everyone , it is no longer a mystery.
Cutting tool is a tool , usually with super-hard carbide or high speed steel materials processing and manufacturing , machinery manufacturing is a tool used to cut materials. Manufacture of cutting material properties better, have a very high hardness , if the hardness is not enough, when drilling or cutting of metal , not only cut down but will not damage the tool. Better wear resistance , but also must have a high flexural strength and impact toughness. The only way to cut a variety of materials devices. High-speed steel is the preferred material for the manufacture of cutting knife , it has a high flexural strength and impact toughness, followed by carbide materials. There cermet, ceramics , PCBN and PCD and other raw materials are manufactured ideal cutting knife .
With the improvement of science and technology, hardness, bending resistance , toughness of the material processing will be enhanced , can prolong life, but it also has its drawbacks , it is difficult for cutting . This requires the material to be suitable for the cutting operation difficult , to do this, the tool must vapor deposited coating technology, the high toughness and high strength matrix deposition coating hardness higher efforts . Design should be reasonable, raise the cutting blade manufacturing technology , the use of ultra-fine particles of carbide materials and the manufacture of high -end products to , in order to meet the needs of market development. Good cutter to go to a multiplier effect.
Cutter has a different classification, forms processing by the device surface can be divided into five categories: the outer surface of a variety of cutting tools , thread cutting tools , gear cutting tools , cutting tools. In addition, the combination tool . According to the shape of the blade can be divided into general tools, forming tools, develop into a tool .
We want to continue to develop cutting tool materials , uses, continuously improve its quality, to make it better serve humanity.
