Imported bearings are selected for active measurement; active loading and unloading. It not only improves the production power; it also reduces the labor intensity of the workers. From the perspective of grinding accuracy; the other advantage is that the machining accuracy is relatively simple. In the single-head vertical surface grinding machine; the workpiece needs to be positioned twice. Two processing; its positioning error, the orientation error of the grinding wheel relative to the magnetic table and the inequality of the magnetic table are reflected on the end face of the ferrule. When the double end grinding is performed; the surface to be processed is the positioning surface. Moreover, the two end faces are ground at one time; this avoids the superposition of positioning errors and processing errors; there is also no processing error caused by the unevenness of the magnetic table and the lack of magnetic force to cause deformation of the workpiece. It is proved that when processing small and medium ferrules; The accuracy of the ferrule width variation can be significantly improved compared to the vertical axis plane grinding accuracy. In addition, the double-face grinding uses the pipeline method to successively grind the ferrule; it is easy to complete the active; and the joint production line is produced. Because of grinding There is no need for a magnetic chuck; it is better to cut thin workpieces; and to eliminate the auxiliary operations such as demagnetization;
There are many varieties of double-face grinding; depending on the movement of the work; it can be divided into the following five categories:
I. Straight through.
Straight-through operation principle This is the best grinding method with high power and simple completion. Its application range is mainly for circular shaped workpieces; such as imported bearing rings, washers, piston rings, etc.
2. The ring is solitary.
The arc-through working principle is a high-power and abbreviated grinding method. This method is mainly suitable for small workpieces with irregular shapes; such as small imported bearing rings, miniature ferrules, rollers, etc.
