  • About tool passivation

    Date:2020.08.18
    What is tool passivation? Improve tool quality and prolong tool life by deburring, leveling, and polishing the tool. The name of a process before coating after finishing grinding of a tool is not uniform at home and abroad, such as “blade passivation”, “blade strengthening”...
  • About PCD processing

    Date:2020.08.17
    PCD is hard, very hard. This makes the indexable blade with welded PCD tips extremely resistant to wear. Therefore, it is often used to process carbon fiber reinforced plastics (CFRP).PCD is very hard, and the complex process of grinding and welding an indexable blade with A PCD tip to the final ...
  • Under what circumstances should CBN tool be changed?

    Date:2020.08.14
    CBN is synthesized under high temperature and high pressure, and its hardness is second only to diamond. Besides, its thermal stability is much higher than diamond, with good chemical stability and no chemical reaction with ferrous metal elements at 1200 ~ 1300℃. Therefore, CBN tools are mainly u...
  • The reason why the precision of the workpiece is unstable in Summer

    Date:2020.08.13
    For high-precision processing, the temperature problem is absolutely not to be ignored, because the temperature difference is the enemy of precision. To be specific, materials will expand and contract in heat and cold. The steel we use will expand in a straight line to produce a change of 12 m pe...
  • Processing characteristics of CBN tools

    Date:2020.08.11
    CBN, hardness after diamond.CBN is an extremely hard tool material second only to diamond and generally works best when the hardness of the material is greater than 48HRC (CBN wears out quickly when soft materials are processed). Temperature up to 2000℃ is also excellent red hardness. Although mo...
