Secret of high durability of alloy left drilling tungsten steel left bit
Alloy left drill, commonly known as tungsten steel left drill, left bit, widely used in automatic lathe industry. The material used in cemented carbide left bit is cemented carbide, which has high hardness. At present, it is only low and diamond superhard material in the world. Its physical hardness is above HRA90. Because the material contains tungsten and cobalt, the hardness and wear resistance are significantly improved. The left drill made of cemented carbide is the left drill with the best durability. Cemented carbide tungsten steel left drill coating was coated with aluminum titanium titanate (TIALN) coating on the left drill surface of tungsten steel. The color of the coating is black and purple. Due to the addition of aluminum element, the hardness of TiALN coating is increased by 33%. The hardness of TiALN coating varies from about Hv3000~4000, bit coating to make it have higher hardness and strength, and the life of the bit is longer. The service life of cemented carbide left drill (tungsten steel coated left drill) is 3 times 4 times that of white steel titanium plating left drill. Tungsten steel alloy coated left drill is not widely used at present, the main reason is that the coating will increase the price of the bit, the automatic lathe left drill manufacturer has a process of understanding it, but most of the bosses and masters who have been introduced through the technical guidance of our Yinhua tool company think that this kind of left drill has good drilling effect, high performance-price ratio and long service life, so it is consistent and satisfactory to this kind of left drill. And said will continue to use and will recommend an automatic lathe industry friend factory. This is the secret of the high durability of alloy left drilling tungsten steel left bit, which I believe you already understand.
