  • 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...
  • Maintenance of CNC equipment in Summer

    Date:2020.08.10
    As the hot summer comes, the temperature in some workshops is also rising. As a result, the precision equipment in the workshops starts to have problems, the machining accuracy becomes unstable, on and off, and some machine tools break down for many times and strike from time to time. Have these ...
  • Cutting tool edge passivation technology

    Date:2020.08.06
    The technology of cutting edge passivation is not a general concern, but a very important aspect. Its importance lies in the fact that the passivated tool can effectively improve the strength of the cutting edge, increase the tool life, and the stability of the cutting process. Well-known technic...

  • How to use cooling in grinding process?

    Date:2020.07.30
    Rational use of cooling methods In grinding, a strong airflow layer is generated on the surface of the grinding wheel rotating at a high speed, so that the cooling fluid is difficult to enter the grinding zone, and a large amount of cooling fluid is poured on the machining surface which has left ...
  • Correct selection of grinding wheel

    Date:2020.07.29
    Cutting section cutting force in grinding, the unit about 1 x 105 ~ 2 x (105) N/was, it has dozens of times more than the limit strength of materials, has such a big cutting force. It is clearly not caused by the strength of the processed material resistance, but by the grinding process of cuttin...
  • How to select the grinding amount?

    Date:2020.07.28
    In order to reasonably select the grinding amount, the relationship between the surface temperature of the grinding area and the grinding amount must be analyzed first. Taking plane grinding as an example, the calculation problem of reducing the grinding area to a semi-infinite heat field with a ...
  • Overview of grinding burns

    Date:2020.07.27
    What is a grinding burn? During grinding, due to the instantaneous high temperature in the grinding area (generally 400-1500 ℃), the surface layer of the workpiece tissue changes locally, and some parts of the surface appear discoloration (namely the color of the oxide film – yellow, brown,...
