Overview And Classification Of Grinding Wheels

Jun 09, 2017

    Grinding wheel, also known as consolidation abrasive, grinding wheel is a combination of ordinary abrasive into a certain shape (mostly round, the central through-hole), and has a certain strength of the consolidation abrasive. Which is generally composed of abrasive, binder and pores, these three parts are often referred to as the three elements of consolidation abrasive. According to the different classification of binding agents, common are ceramic (binding agent) grinding wheel, resin (bonding agent) grinding wheel, rubber (bonding agent) grinding wheel. The grinding wheel is the largest amount of abrasive, the most widely used one, the use of high-speed rotation, metal or non-metallic parts of the cylindrical, inner circle, plane and various types of rough grinding, Grinding and grooving and cutting.Grinding wheel

    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 grinding quality, productivity and economy. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bonding agent, hardness, organization, shape and size.Grinding wheel

    A wide variety of grinding wheels. According to the abrasive can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel and natural abrasive super hard abrasive and (diamond and cubic boron nitride, etc.) grinding wheel; according to the shape can be divided into flat grinding wheel, bevel 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 and so on. Grinding wheel characteristics of the main parameters of abrasive, particle size, hardness, bonding agent, shape, size and so on.Grinding wheel

    As the grinding wheel is usually working at high speed, it should be carried out before the rotary test (to ensure that the wheel at the maximum operating speed, will not break) and static balance test (to prevent the work caused by machine vibration). After a period of time, the grinding wheel should be trimmed to restore grinding performance and correct geometry.
