直線導軌防護罩的硬度檢驗方式您了解嗎?

來源:http://www.3553885.live/ 日期:2019-12-31 發布人:admin

  直線導軌防護罩的性能直接影響其加工質量,其中硬度值是決定鑄件加工質量的重要指標。

  The performance of linear guide protective cover directly affects its processing quality, and the hardness value is an important index to determine the processing quality of castings.
  布氏硬度:主要用于測定鑄造、鍛造、有色金屬零件、熱軋鋼坯的硬度和退火,測量范圍≯HB450。
  Brinell hardness: it is mainly used to determine the hardness and annealing of casting, forging, non-ferrous metal parts and hot-rolled steel billets, and the measurement range is no more than hb450.
  2. 洛氏硬度:HRA主要用于高硬度試件,用于測定材料和表面硬度高于HRC67的材料,如硬質合金、氮化鋼等。測定范圍為HRA>70。HRC主要用于鋼件(如碳鋼、工具鋼、合金鋼等)淬火、回火后的硬度測定。測量范圍為HRC20~67。

  2. Rockwell hardness: HRA is mainly used for high hardness test pieces, for measuring materials and materials with surface hardness higher than hrc67, such as cemented carbide, nitriding steel, etc. The determination range is HRA > 70. HRC is mainly used for hardness measurement of steel parts (such as carbon steel, tool steel, alloy steel, etc.) after quenching and tempering. The measurement range is hrc20 ~ 67.
  3.維氏硬度:用于測定薄壁件和導軌護罩的硬度,也可用于測定滲碳、氰化、氮化等表面硬化機床鑄件的硬度。
  3. Vickers hardness: it is used to measure the hardness of thin-walled parts and guide rails, and also used to measure the hardness of surface hardening machine castings such as carburizing, cyaniding, nitriding, etc.
