The choice of abrasive particle size can not be separated from the grinding conditions and grinding
2012-09-24 by seoer10

    The size of the abrasive particles is referred to as particle size, particle size, the grinding quality, production efficiency is closely related to the particle size represented by the size number. 4 # -240 # screening method and classification; called micronized symbol W indicates the abrasive particle size is the basic size of the micronized. The basic dimensions of the abrasive particle size range, are shown in Table 01. Select the the ordinary abrasive particle size, can not be separated from the grinding method and grinding conditions. Typically, high grinding efficiency, roughness, ceramic grinding wheel or grinding wheel china in contact with the workpiece surface, the workpiece material toughness and ductility larger requirements. And machining of thin-walled parts, to be elected coarser granularity; while grinding hard and brittle materials, fine grinding, forming grinding, high speed grinding, you should choose a finer granularity.
  Choice of superhard abrasive particle size, can not be separated from the processing requirements, grinding conditions and a better range of grinding. Typically, coarse grinding use 80 # to 120 #; semi-fine grinding Optional 120 # to 180 #; the fine grinding chosen 180 # W40; grinding, polishing selection of W40 to W1.

      For the special requirements of the grinding, the particle size of the abrasive can be appropriately adjusted, such as forming of grinding, in order to improve the formability of abrasive, the granularity of the selected particle size than the average grinding to fine.
