  • Drill grinder

    Date:2020.09.11
    A drill grinder is used to repair and grind a 3-75mm large bit machine, at the same time can also repair and grind end milling cutter, tap, chamfer cutter, grinding workpiece outer circle, etc., high precision, very convenient operation. When grinding tools of different materials, regrinding can ...
  • Diamond and CBN abrasive particle size control

    Date:2020.09.05
    Particle size is directly related to grinding quality, especially surface roughness. For the same kind of abrasive particle size, the sharper the processing efficiency is higher, the more rounded the surface quality is better (the surface roughness value is smaller).In general, round particles ar...
  • Wear of PCD tools

    Date:2020.09.02
    PCD tools can be used in the precision machining of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high si-Al alloy, and other tough non-ferrous metal materials. There are many types of diamond cutting tools with significant differenc...
  • PCD laser cutting machine

    Date:2020.08.31
    Laser cutting is a new cutting method and also one of the important aspects of laser material processing technology. Super-hard materials are through the control of high precision solid laser cutting machine, energy, and the width of laser pulse peak power and repeating frequency parameters, emit...
  • The prevention of CNC equipment

    Date:2020.08.19
    The factory should install an air-conditioning system to maintain the right temperature, especially for precision CNC equipment, this is the most basic requirement. Otherwise, frequent failure, processing quality is not stable, this kind of unwillingness to pay the result is definitely not worth ...
  • 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...
