(1) super hard tool. The so-called superhard materials refers to synthetic diamond and cubic boron nitride (CBN), and the use of these powders and binder sintered polycrystalline diamond (PCD) and polycrystalline cubic nitriding (PCBN) and so on. Superhard materials with excellent wear resistance, mainly used in high-speed cutting and difficult cutting materials processing.
(2) ceramic cutting tools. Ceramic tool has a high hardness, wear resistance and good high temperature mechanical properties, and metal affinity is small, easy to produce bonding with the metal, and good chemical stability. Ceramic cutting tools are mainly used in steel, cast iron and its alloys and difficult processing of cutting materials, can be used for ultra-high-speed cutting, high-speed cutting and hard material cutting.
(3) coating tool. Tool coating technology since the advent of the improvement of tool performance and processing technology plays a very important role in the coating technology will be coated with a layer of traditional film, the tool performance has undergone tremendous changes. The main coating materials are: Tic, TiN, Ti (C, N), TiALN, ALTiN and so on. Coating technology has been used in end mills, reamers, drill bits, composite hole machining tools, gear hobs, shaper shaper, shaving cutter, forming broach and various machine holder indexable inserts to meet high speed machining Strength, high hardness cast iron (steel), forged steel, stainless steel, titanium alloy, nickel alloy, magnesium alloy, aluminum alloy, powder metallurgy, non-metallic materials such as the production of different requirements of the workpiece.
(4) Carbide. Hard knives are the leading products of CNC machining tools. In some countries, more than 90% of the turning tools and more than 55% of the milling tools are made of carbide, and this trend is increasing. Carbide can be divided into ordinary hard alloy, fine grain cemented carbide and supercrystalline cemented carbide. According to the chemical composition of distinction, can be divided into tungsten carbide-based carbide and carbon (nitrogen) titanium-based cemented carbide. Carbide in the strength, hardness, toughness and process has excellent overall performance, almost any material for cutting.
(5) high speed steel cutting tools. High-speed steel is a high alloy steel that joins more alloy elements such as W, Mo, Cr and V. High-speed steel cutting tools in the strength, toughness and process, and so has a good overall performance in the complex tool, especially the manufacture of hole processing tools, milling cutter thread cutter, broach, cutting tool and other blade-like complex tool, Occupy the main position.
