Grinding wheel is the main tool for grinding, it is composed of abrasive and binder porous objects. The abrasive, binder and pore are the three basic elements of the grinding wheel. With the abrasive, binder and grinding wheel manufacturing process, grinding wheel characteristics may vary widely, the grinding accuracy, roughness and production efficiency has an important impact. Therefore, the appropriate grinding wheel must be selected according to the specific conditions.
The characteristics of the grinding wheel by the abrasive, particle size, hardness, bonding agent, Grinding Wheel shape and size and other factors to decide,
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 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 is the most important type of abrasive grinding. A grinding wheel is a porous body made of a binder, a compact, dried and roasted in an abrasive. Because of the different abrasive, Grinding Wheel binder and manufacturing techniques, the characteristics of the grinding wheel are very different and thus have a major impact on the grinding quality, productivity and economy. The characteristics of the grinding wheel are mainly determined by abrasive, particle size, bonding agent, hardness, organization, shape and scale.
Role: grinding wheel is the largest amount of abrasive, the use of the most extensive one, the use of high-speed rotation, metal or non-metallic parts of the cylindrical, inner circle, Grinding Wheel plane and various types of rough grinding, Grinding and grinding and grooving and interception.
According to the abrasive used can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel and natural abrasive super hard abrasive and (diamond and cubic grinding wheel boron nitride, etc.)
According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, cup-shaped grinding wheel, disc-shaped wheel, etc .; according to the binder can be divided into ceramic grinding wheel, resin wheel, rubber wheel, metal wheel. The characteristics of the grinding wheel are mainly abrasive, viscosity, hardness, bonding agent, shape, scale and so on.
Cleaning: In the production process to use the abrasive wheel grinding on the belt. Usually grinding wheel work 5-7 days to remove the cleaning. (Above the polished rubber debris, Grinding Wheel through the high temperature conflict tightly attached to the surface of the emery, it is difficult to clean)
