introduction：1Clamping with two center holes Generally, the important outer circular surface is used as the coarse reference location，Machining the center hole，Then the center holes at both ends of the shaft are used as the precision reference for positioning；Try to be as consistent as possible、Reference coincidence、Mutual reference，Multiple surfaces can be machined in one installation。The center hole is the unified positioning benchmark and inspection benchmark for workpiece processing，Its own quality is very important，Its preparation is also relatively complex，It is often positioned with a supporting journal，car（drill）Central taper hole；Then locate the center hole，The fine car is round；Outer circle positioning，Rough grinding cone holes；Position with center hole，Fine grinding outer circle；Finally, it is positioned by the outer circle of the supporting journal，finishing（scraping

introduction： The grinding effect of each particle is very different during grinding，As shown in the figure。 （1）The more protruding and sharp abrasive particles on the grinding wheel play a cutting role These abrasive particles at the beginning of contact with the workpiece，Because the depth of cut is very small，The negative front Angle of the arc of the abrasive edge is very large，Only elastic deformation occurs on the surface of the workpiece；As the depth of cut increases，The pressure between the abrasive particle and the surface of the workpiece increases，The surface of the workpiece is plastic deformed and grooved；As the cut deepens further，The cut metal layer can produce significant slippage and form chips。This is a typical cut of abrasive particles
