The commonly used method in the grinding of shaft workpieces is cylindrical grinding. There are four most commonly used methods for cylindrical grinding.
Mainly through the high-speed rotation of the grinding wheel, the rotation of the workpiece, and then the vertical movement of the grinding wheel to realize the grinding effect of the workpiece. However, the efficiency is relatively low, the surface quality of the workpiece after grinding is better, and the surface roughness of the workpiece is relatively low.
Roughly similar to the longitudinal grinding method, at this time, the horizontal grinding force is mainly applied to the workpiece through the grinding wheel, rather than the up and down movement of the worktable. For this grinding method, the efficiency is relatively high. However, due to the increase of the grinding force during grinding, a certain amount of heat will be generated, which will increase the grinding temperature. When the temperature is too high, it is necessary to provide sufficient coolant for cooling.
It mainly effectively combines the two methods of horizontal grinding and longitudinal grinding, first through the horizontal grinding method and then through the longitudinal grinding method for processing. By combining the two methods, both high-efficiency grindings are realized, and the quality of grinding is ensured simultaneously.
This kind of grinding method is more efficient, but there is a problem that the dressing process of the grinding wheel is more complicated, and the specific structure of the workpiece needs to be considered. Moreover, there are clear requirements for the grinding wheel's cut-in length and cut-out length, and it must reach a length.
For the above four commonly used methods, since each method has its own advantages and disadvantages, it should be selected according to specific requirements during actual processing. ETCN
