The Development Trend of New Tools in Precision Parts Processing

Milling cutters are a type of multi edge cutting tool in precision parts processing. With the development of modern industry, there are more varieties and specifications of milling cutters. On the basis of various standard milling cutters, the improved design of the new milling cutter has the following characteristics: using various new tool materials, the new milling cutter has higher strength, hardness, and wear resistance. On the basis of the existing universal high-speed steel, high-speed steel has developed high-performance high-speed steel and powder high-speed steel, as well as surface coating and strengthening treatment of high-speed steel cutting tools.

Hard alloy is one of the most important cutting tool materials in precision parts processing. In some industrialized countries, hard alloy cutting tools have greatly surpassed high-speed steel cutting tools. The development direction of hard alloys is coating hard alloys, ultrafine grain hard alloys, and titanium based hard alloys. There has also been further development in the application of superhard tool materials in milling cutter blades.
