Characteristics of grinding:

Because the width of the 4.5 inches grinding wheel is large, the main pumping arm has larger elongation.
Because the grinding width is large, so the grinding force, grinding power is also relatively large, the heat generated from grinding is also more.

In order to ensure the shape and position accuracy of the workpiece, it is required that the hardness of the 4.5 inches grinding wheel should be raised uniformly only in the circumferential direction, and the axial uniformity must be good, otherwise the uneven wear of the grinding wheel will affect the accuracy and surface quality of the workpiece.

After the grinding wheel is formed and dressed, the forming surface can be grinded to ensure the forming degree of the workpiece. At the same time, the cutting-in grinding mode is adopted, which is more efficient than the longitudinal reciprocating grinding.

Because of the above grinding characteristics, wide 4.5 inches grinding wheel grinding is suitable for grinding a large number of wall workpieces, such as spline shaft, motor shaft, twist drill, sewing machine under the axle, automobile and tractor drive shaft.
