  • PCBN tool material performance

    Date:2020.05.06
    PCBN tool material performance (1) high hardness and wear resistance. CBN single-crystal microhardness of HV8000 ~ HV9000 is the second known high hardness material. The hardness of PCBN tool materials with different bonding amounts is between HV4000 ~ 6000, while the hardness of carbide tool mat...
  • CBN tool material manufacturing method

    Date:2020.05.05
    CBN (Cubic Boron Nitride) was first synthesized in the 1950s by American general electric (GE) under high temperature and high pressure by the artificial methods. Its hardness reaches HV8000, which is second only to diamond (HV10000) and much higher than other materials. It and diamond are collec...
  • Treatment of CBN raw materials

    Date:2020.04.30
    Treatment of raw materials There are impurities such as WBN, HBN, pyrophyllite, graphite, magnesium, and iron in CBN micro powder. In addition, it and the binder powder contain adsorption oxygen, water vapor, etc., which is not good for sintering. Therefore, the purification of raw materials is o...
  • Notes for tool grinding

    Date:2020.04.29
    Notes for tool grinding When you use our super-hard tool grinding machine for grinding tools, please note them. 1) pay close attention to the contact between the grinding wheel and the workpiece surface during operation. When the surface of the workpiece just contacts the grinding wheel, continuo...
  • Grinding fluid kinds

    Date:2020.04.28
    The cutting speed of grinding is high, so the power consumed during cutting is large, and most of its energy is converted into heat energy. This heat does not pass deep into the workpiece but concentrates on the surface of the workpiece. So there is a large temperature difference between the surf...
  • Steps of cutting edge grinding of turning tool

    Date:2020.04.27
    Methods and steps of cutting edge grinding of turning tool: 1. First, grind off the welding slag on the front and the back and then smooth the bottom surface of the lathe tool. The alumina grinding wheel with size no. 24-36 can be used. 2. Roughen the hilt of the main back and the secondary back:...
  • HRC55 above hardened steel gear hard turning tool -CBN blade

    Date:2020.04.24
    Hardened steel gear is one of the typically difficult to process materials, the common material is 20CrMnTi, 42CrMo. After quenching hardness hrc58-62, the traditional tools are generally not processed, not moving, is not wear or break. At present, the main processing HRC55 above hardened steel g...
