1.Ceramic tool. Ceramic tool has high hardness, wear resistance and good high temperature mechanical properties, small affinity with metal, not easy to bond with metal, and good chemical stability. Ceramic tool is mainly used in the cutting of steel, cast iron and its alloys and difficult materials. It can be used for ultra-high speed cutting, high speed cutting and hard material cutting.

2.super hard tool. The so-called super hard material refers to artificial diamond and cubic boron nitride (abbreviated as CBN), as well as the polycry stalline diamond (abbreviated as PCD) and polycry stalline cubic nitride shed (abbreviated as PCBN) by sintering these powders and binders. Superhard materials have excellent wear resistance and are mainly used in the machining of high speed cutting and difficult cutting materials.

3.Coating tool. Since the introduction of tool coating technology, it has played a very important role in the improvement of tool performance and the progress of processing technology. After coating technology coated the traditional tool with a thin film, the tool performance has undergone great changes. The main coating materials are Tic, TiN, Ti(C, N), TiALN, ALTiN and so on. Coating technology has been applied to end milling cutter, reamer, drill, compound hole machining tool, gear hob, gear shaper , shaver, forming broach and a variety of machine clamp indexable blades. Meet the high speed machining of high strength, high hardness of cast iron (steel), forged steel, stainless steel, titanium alloy, nickel alloy, magnesium alloy, aluminum alloy, powder metallurgy, non-metal and other materials of the production technology of different requirements.

   4.Tungsten Carbide. Carbide inserts is the leading product of CNC machining tools, some countries have more than 90% of the turning tool and more than 55% of the milling cutter are made of hard alloy, and this trend is increasing. Hard alloy can be divided into ordinary hard alloy, fine grained hard alloy and super grained hard alloy. According to the chemical composition, it can be divided into tungsten carbide and carbon (nitrogen) titanium carbide. Hard alloy has excellent comprehensive properties in strength, hardness, toughness and technology, and can be used in almost any material machining.

   5.High speed steel tool. High speed steel is a kind of high alloy tool steel with W, Mo, Cr, V and other alloying elements. High speed steel tools have excellent comprehensive performance in strength, toughness and technology, etc. High speed steel still plays a major role in complex tools, especially manufacturing hole machining tools, milling tools, thread tools, broaching tools, cutting tools and other complex edge tools.
