Commonly used tool materials are divided into: tool steel (including carbon tool steel, alloy tool steel, high-speed steel), hard alloy, superhard cutting tool materials (including ceramics, diamond and cubic boron nitride, etc.)
Generally speaking, tool steel. High speed steel.Cemented carbideCermetCBN cubic boron nitridePCD diamond
Other tool materials:(1) ceramic cutting tool: a kind of cutting tool made of alumina (Al2O3) or silicon nitride (Si3N4) as matrix, and then adding a small amount of metal at high temperature.(2): artificial diamond is an allotrope of carbon, is currently the most hard tool materials, the micro hardness is 10000HV.
High speed steel: high speed steel tool especially in the manufacture of forming the complex structure of the drilling tool such as milling cutter, broach, gear cutting tools, thread cutting tools; the hardness of high speed steel, wear resistance, heat resistance than hard alloy cutting tools, therefore only suitable for the manufacture of medium and low speed cutting. High speed steel is divided into two categories according to its performance: ordinary high speed steel and high performance high speed steel.Cemented carbide: a large number of cemented carbide in the application of good rigidity, blade shape of the high-speed cutting tool, with the progress of technology, complex tools are gradually expanding its application.Tool coating material: hard alloy or high speed steel cutting tool by chemical or physical methods on the surface coated with a layer of abrasion resistance of refractory metal compounds, which can improve the wear resistance of the tool material, and not reduce the toughness.
