Grinding is the most minor of a class of abrasive

Can be divided according to the ordinary abrasives abrasives (corundum and silicon carbide, etc.) and natural abrasive grinding wheels and superabrasive (diamond and cubic boron nitride) grinding wheel;
 Shape can be divided according to level grinding wheels, bevel wheel, cylindrical grinding wheels, cup wheels, disc wheel, etc.; binding agents can be classified according to the ceramic grinding wheel, resin grinding wheel, rubber wheel, metal grinding wheel. Characteristic  abrasive sanding belt parameters of the wheel with secondary abrasive, viscosity, hardness, binders, shape, size and so on.
As usually at high speed wheel task, so use should be stopped before turning experiments (to ensure tasks at the highest speed wheel will not break) and static equilibrium experiments (to avoid machine vibrations caused by the task). Wheel in the task for some time, you should stop grinding trimmed to restore function and correct geometry. Grinder with a grinding wheel is characterized by:
As violent friction, leaving the grinding zone temperature is high. This will form the stress and deformation of the workpiece occurs, even the formation of the workpiece appearance burns. Therefore necessary to inject a small amount of grinding coolant to reduce Mounted flap wheel  the grinding temperature. Coolant can also play the role of BTA and smooth. Grinding large radial forces. This will form a machine - wheel - workpiece flexibility piecemeal concessions, so practice cutting depth less than the nominal depth of cut. Thus grinding to be completed, you should not feed stop light grinding to eliminate errors.
After blunt abrasive, grinding force also increased, resulting in grain crushing or scattered, re-exposed sharp edge, this feature is called "self-sharpening." Self-sharpening grinding in a certain day within the normal stop, but beyond a certain task day after manual trimming should be stopped to avoid grinding force increases caused by vibration, noise  flap disc and damage the workpiece surface quality. As abrasive wheel itself has high hardness and heat resistance, and thus high hardness grinding can process information, such as hardened steel, carbide, etc.. Grinding wheel and the grinding process piecemeal resolution characteristics can be averaged trace cutting, general ap = 0.001 ~ 0.005mm; grinding speed is high, normal up to v = 30 ~ 50m / s; grinder stiffness; adopts hydraulic transmission, Thus grinding energy economically achieve high precision (IT6 ~ IT5) and the appearance of small roughness (Ra = 0.8 ~ 0.2μm). Grinding is one way of parts finishing secondary
