Wide grinding wheel for improving production efficiency

Wide wheel grinding is also a kind of high-efficiency grinding, which improves the grinding efficiency by increasing the grinding width.

Generally, the width of external grinding wheel is only 50mm, while the width of wide grinding wheel can reach 300mm. The width of grinding wheel for surface grinding can reach 40mm, and the width of wide wheel for centerless grinding can reach 800-1000mm; In the cylindrical and surface grinding, the force cutting internal cutting method is generally used. In addition to the cutting method, the centerless grinding also uses the through grinding method to grind the workpiece with a wide grinding wheel. The dimensional accuracy can reach grade 6, and the surface roughness can reach grade 6 ra0.06um.

Characteristics of grinding:

Due to the large width of the grinding wheel, the extension of the main pumping cantilever is large.

Due to the large grinding width, the grinding force and power are also relatively large, and the heat produced by grinding is also large.

In order to ensure the shape and position accuracy of the workpiece, the hardness of the grinding wheel is required to be uniform only in the circumferential direction, and the axial uniformity is also better. Otherwise, the accuracy and surface quality of the workpiece will be affected due to uneven wear of the grinding wheel.

After shaping and dressing, the grinding wheel can be ground into a shaped surface to ensure the forming degree of the workpiece; At the same time, cutting in grinding is adopted, which is more efficient than longitudinal reciprocating grinding.

Due to the above grinding characteristics, wide grinding wheel grinding is suitable for grinding a large number of wall workpieces, such as spline shaft, motor shaft, twist drill, sewing machine lower shaft, automobile and tractor drive shaft, etc.
