The grinding wheel consists of three parts: abrasive, binder (binder), porosity
The characteristics of the grinding wheel vary widely and therefore have an important impact on the grinding quality, productivity and economy. Grinding Wheel The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bonding agent, hardness, organization, shape and size.
A wide variety of grinding wheels.
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 boron nitride, etc.)
According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, cup-shaped wheel, disc-shaped wheel, etc .; Grinding Wheel according to the binder can be divided into ceramic grinding wheel, resin wheel, rubber wheel, Grinding wheel characteristics of the main parameters of abrasive, particle size, hardness, bonding agent, shape, size and so on.
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.
The grinding wheel is made of abrasive and binder, etc. Grinding Wheel The center has a circular through the hole of the abrasive.
1, abrasive: grinding wheel is the main grinding part, with sharp edges and corners, that is, a small cutting edge, to cut the workpiece, abrasive is often very hard material, usually compounds, such as emery (chemical composition is silicon carbide) , Corundum (chemical composition is aluminum oxide), diamond, etc., Grinding Wheel the most common is the abrasive wheel and corundum wheel.
2, the binder: According to the use of different grinding wheel, ceramics, resins, rubber, metal, etc., its main role is to adhere to the abrasive together to form a certain shape of the wheel.
3, the pores: the pores are the main components of the wheel, Grinding Wheel the purpose of the pores is to reduce the bonding strength of the adhesive, storage grinding down the grinding steel scrap, when the small abrasive sharp part of the bald, it will be due to the combination of pores Reduced strength and peeling, revealing new sharp abrasive, conducive to further grinding.
