Selection points of grinding wheel for grinding bearing raceway

(1) Choose the grinding wheel according to different process arrangements. Rough and fine grinding in one process, or coarse and fine grinding in two processes, there should be a difference when choosing a grinding wheel;

(2) Choose the hardness of the grinding wheel appropriately. The grinding wheel is too hard. Although the groove R changes little, the grinding wheel is more durable, but the cutting ability of the grinding wheel is reduced, and it is not easy to grind the margin. The surface of the grinding wheel is easy to be wall plugged and the workpiece is easy to burn. If the grinding wheel is too soft, the sand will fall off too quickly and the wear scar will be deeper. Without a polishing process, the surface finish and accuracy of the workpiece cannot be easily guaranteed. At the same time, the grinding wheel is expensive and uneconomical.

(3) When grinding the outer groove of the bearing, it is similar to internal grinding. The speed of the grinding wheel is lower. If the diameter of the grinding wheel is large, the hardness should be lower; if the diameter of the grinding wheel is small, the hardness of the grinding wheel for grinding the outer groove is generally based on the part It depends on the size, but grinding a certain

For some large-size bearings, it is not necessary to choose a larger grinding wheel, because after the diameter of the grinding wheel increases, the arc in contact with the surface of the workpiece is also larger, the wear scar (grinding wheel flower) increases, and the finish is reduced. When grinding the bearing inner groove, it is similar to the cylindrical grinding, and the grinding conditions are better;

The size of the grinding wheel does not change much, but the thickness of the grinding wheel is different. Generally, the hardness of the thick grinding wheel is softer, and the thinner wheel is harder.

(4) When grinding precision bearings, the process should be strictly distinguished. The grinding wheel should be finer than the general use, and the hardness should be softer to achieve a higher finish without burns. The selection of the above-mentioned grinding wheel for grinding the bearing groove refers to the use of ordinary pendulum grinding method. If the groove is ground by the plunge grinding method, a ceramic bond grinding wheel is required.
