In recent years, with the development of China's machining industry, carbide cutting tools have gradually been paid attention to and applied to mechanical cold working. Practice has proved that the hard alloy material tool in mechanical cold working has a very good application effect, worthy of further study, introduced the hard alloy material tool, and then a detailed analysis of the hard alloy material tool in the mechanical cold working of the six forms of application, tool is an important tool for mechanical cold working, the use of good quality tool can not only ensure the quality of mechanical products, but also can improve the processing efficiency of mechanical products. Cemented carbide material is a new type of mechanical material, durability, good quality, especially low cost, suitable for mechanical cold working, therefore, carbide cutting tools are widely used in mechanical cold working,Superhard Tool SolutionsIt is particularly important, then, let's learn about the application of superhard tool solutions in mechanical cold processing!

1. Carbide cutting tools

The hardness of cemented carbide tool material is close to that of diamond and CNB, and it has strong bending resistance. The use of this material for mechanical cold processing, not only can make up for the traditional tool material bending deficiency, but also can solve the problem of insert welding card difficult, to obtain effective mechanical cold processing quality, it is important that the cost of this material is very low, can reduce the cost of mechanical cold processing input. In recent years, with the improvement of the production technology of artificial hard material tools, the application range of hard materials has been greatly expanded, and it is used in deep processing, semi-finishing and roughing. Practice has proved that the life of superhard materials is very high, which greatly shortens the machining process.

2.1 turning machining

Turning refers to the use of linear or curvilinear movement of the tool on the lathe to form blank products, cutting dimensions, and produce mechanical products that meet the design drawings. This is one of the common methods in the production of mechanical products, and its application is based on cutting tools. In turning, the tool material must have sufficient hardness, wear resistance, heat resistance and toughness. The hardness and wear resistance of alloy steel, tool steel, carbon steel, cobalt high speed steel and other tool materials are far inferior to carbide materials. Practice has proved that the cutting depth of cemented carbide tools is much higher than the grinding height, and the processing efficiency is very high. The cost is only 80%. Taking 45HRC hardened steel as an example and PCBN as tool material, the cutting speed can be maintained at about 10020 m/min.

2.2 milling

Milling is a fixed blank, with a milling cutter for cutting. In this way, complex mechanical products can be processed on the CNC lathe. For example, molds, fixtures, etc. Unlike turning, for milling cutters, the cutter rotates at high speed. This means that the cutting performance is good even at high temperatures, and the wear resistance will not be easily damaged. In contrast, carbide materials can be selected to be machined into tools. Using PCD artificial polycrystalline diamond to make cutting tools, the processing speed can reach 4000 m/min, which can effectively shorten the processing time and improve the processing efficiency. In addition, the relevant data show that the high processing speed of milling with PCD can reach 4012 m/min. It can be seen that the application of carbide cutting tools in milling can effectively provide mechanical cold working efficiency and product quality. Superhard Tool Solutions

2.3 boring machining

Boring is a kind of inner diameter cutting technology, whether it is roughing or finishing. In general practical applications, non-standard tools are mainly used for boring. In addition, boring processing with rough machining, in, finishing. Relevant research shows that when using high boring ordinary steel, the processing speed can only reach 50 m/min. When using carbide tools for rough machining, the high machining speed can reach 60 m/min. When finishing, the high speed can reach 150 m/min.

2.4 reamer machining

Reamer processing is mainly to use the reamer to cut the thin layer of metal on the hole wall to obtain mechanical products with relatively low surface roughness and relatively accurate aperture. Can be processed round hole, cone hole and other mechanical products with holes. Generally speaking, the processing aperture range of the reamer is very small, only 100mm. This means that the tool precision of the reamer is very high. Also, the workpiece being machined is stationary during the reamer process. In addition, the reamer can also be divided into coarse reamer and fine reamer.

In summary, the carbide tool material has obvious application advantages, in the mechanical cold processing, the application of the material can be processed a variety of tools, improve the processing efficiency of mechanical products, processing quality. Therefore, researchers continue to increase the application of cemented carbide materials, give full play to the advantages of cemented carbide materials, promote the innovation and development of mechanical cold working technology in China, and effectively promote the development of China's industry.
