Introduction To The Properties Of Grinding Wheel

Jun 20, 2017

   Grinding wheel is the most important type of abrasive grinding. A grinding wheel is a porous body made of a binder, a compact, dried and roasted. Due to the different abrasives, binders and manufacturing processes, the characteristics of the grinding wheel vary widely and therefore have an important impact on the processing quality, productivity and economy of the grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bonding agent, hardness, organization, shape and size. The grinding wheel is made of abrasive and binder, etc. The center of the circular through the hole of the abrasive. The characteristics of the grinding wheel by the abrasive, particle size, hardness, bonding agent, shape and size and other factors to decide, are described below. Abrasive selection: Abrasive is the main raw material for manufacturing grinding wheels, which is responsible for cutting work. Therefore, the abrasive must be sharp, and have high hardness, good heat resistance and a certain toughness.Grinding wheel

    Particle size and its choice refer to the size of abrasive grain size. Granularity is divided into abrasive and powder two categories. For abrasives with particle sizes greater than 40 μm are called abrasive grains. Classified by screening, and the particle size is expressed as the number of holes per inch in the length of the mesh through which the abrasive particles are passed. Such as 60 # abrasive grain that its size just through the length of each inch through the 60 mesh screen. For the particle size of less than 40μm abrasive, known as the powder. Graded with a microscopic measurement, with W and the following numbers representing the particle size number, and the value after W represents the actual size of the powder. Such as W20 indicates that the actual size of the powder is 20 μm.Grinding wheel

    Mainly related to the processing of surface roughness and productivity. Rough grinding, the grinding margin, the required surface roughness value is larger, should use coarse abrasive. Because the abrasive grain coarse, large pores, grinding depth can be larger, grinding wheel is not easy to plug and heat. Grinding, the margin is small, requiring a lower roughness value, you can choose more fine abrasive. In general, the finer the abrasive, the better the surface roughness.Grinding wheel
