The wheel is the main abrasive grinding. The wheel is in the added binding agents, a porous body made by the green compacts, grinding disc and firing the abrasive. Abrasive, bond and manufacturing processes, grinding wheel characteristics vary widely, so grinding machining quality, productivity and economy. The characteristics of the grinding wheel is mainly determined by the abrasive strength, binding agents, hardness, organization, shape, and size and other factors.

The abrasive is the major component of the wheel, it has a high hardness, wear resistance, heat resistance and a certain degree of toughness to withstand the grinding cutting heat and the cutting wheel, and should also have sharp angles in order to facilitate grinding metal.

Us to explore the principle of considering the abrasive height, bending secondary parabolic and higher order parabolic abrasive angle grinder piece grinding wheel
According to the actual the machined surface busbar equation to determine the abrasive neutral layer curve equation, ie equidistance line equation; through the re-establishment of a mathematical model of abrasive bending mechanics and mathematical knowledge, discuss different loads, abrasive bending formation the parabola process and abrasive width function expression derived under different loads.

By specific examples analysis shows, the bending method is not suitable to meet the standard equation of the cubic parabola workpiece grinding silhouette curve.

?The abrasive bending experiments show that high precision abrasive forming the average error is 0.0462mm; the grinding disc  metal workpiece experiments show, the the fixed abrasives grinding metal workpiece contour of accuracy is high, the average error is 0.0176mm; grinding plastic parts The experiments show that the average error of 0.0327 mm of the sandpaper plastic workpiece.

Since these errors are reduced compared with the results of previous studies have further evidence considering the abrasive height, angle grinding abrasive grinding parabolic workpiece bending and forming method can get higher forming precision.
