Grinding wheel used on the characteristics of

As intense friction, leaving the grinding zone temperature is high. This will cause the workpiece to produce stress and deformation of the workpiece surface and even cause burns. Therefore, a lot of grinding coolant must be injected to reduce the grinding temperature. Also from the coolant and lubrication chip.
Grinding large radial forces. This will cause the machine - grinding wheel - workpiece system flexibility  grinding wheel , the actual depth of cut less than the nominal depth of cut. Therefore, the grinding will be  when the light is not to be infeed grinding to remove the error. After blunt abrasive, grinding force also increased, resulting in grain  grinding wheel  or off, re-exposing the sharp edge, this feature is called self-sharpening. Since sharp grinding in a certain period of time so that can be normal, but  after more  than a certain working time should be carried out manually trimmed to avoid grinding force increases caused by vibration, noise and damage the workpiece surface quality.

As abrasive wheel itself has high hardness and heat resistance, high hardness can be processed so grinding materials such as hardened steel, carbide, etc.. Determine the characteristics of the grinding wheel and grinding grinding system can make even a trace cutting, general ap = 0.001 ~ 0.005mm; grinding speed is high, generally up to v = 30 ~ 50m / s; grinder stiffness; adopts hydraulic transmission, Therefore, grinding can be obtained economically with high precision (IT6 ~ IT5) and a small surface roughness (Ra = 0.8 ~ 0.2m). Grinding is one of the main methods parts finishing
