High speed carbide end mills and carbide of different places that need high speed steel after heat treatment process to improve its hardness, ordinary steel no matter what as long as there is no steel after heat treatment, it is soft.

Cemented carbide end mills is made of hard alloy round bar is made, with universal CNC tool grinder for grinding wheel for steel processing equipment, processing tools, by computer or G code editing processing route of manufacturing a molding and processing method, has the high efficiency, high precision, mass production has the advantages of good consistency so, for the shortcomings of most equipment for imported products, the general price of 1 million yuan or more.

There is the use of ordinary processing equipment, divided into slot grinding machining spiral groove end tooth machining end and end after trimming machine (week tooth machine) this week processing tooth, products need to be processed according to various sections separately, the cost of manpower cost is very high, and the quality of mass production the products are skilled workers themselves rely on operating machine to control, so poor in accuracy and consistency.The quality of cemented carbide end millsalso depends on the selected hard alloy material grades, the general is processed according to the material selection and the gold medal, in general the alloy grain small as possible.

Now the international popular such as the United States is M42 high speed steel grades of high-speed steel and M7 grades, the best comprehensive performance of M42 high speed steel, either by grinding, hardness and red hardness are very good, but the M42 high speed steel containing 8 cobalt, cobalt is scarce non renewable resources, so the price is very expensive M42 in general, 30-20 million, of course, individual production expected recovery of domestic M42 prices will be cheaper, in addition to the popular W18, M2, W9, high speed steel and M2AL, W9AL and other high performance HSS, which focuses on M2AL and W9AL, as the name suggests, the two brands of high speed steel is made with aluminum based on M2 and W9 and aluminum, equivalent to the role of bond of the steel particles close together, so the steel quality will be good, especially M2AL is our specially developed high speed steel to replace M42, the tool used to fabricate this high speed steel in 80 years On behalf of the foreign market once greatly welcomed, but with the market competition and the high speed steel excessive use of recycled material to manufacture, now the performance of this kind of steel or worse than M42, but for the material being processed some special requirements are not particularly high, M2AL is a good choice, after all, much cheaper than M42.

The thickness of the coating on the surface of the milling cutter is about 3 mu. The main purpose is to increase the surface hardness of the milling cutter,general speaking,carbide end millsin hardness and toughness are incompatible, and the emergence of coating technology in a certain extent to solve this situation, such as the selection of cutter Matrix Toughness material, coating on the surface coated with high hardness, such as milling performance has been improved dramatically.
