The bearing is in the grinding process; the surface of the work is ground by a high-speed rotating grinding wheel; therefore, if it is not operated and adjusted according to the operation instructions during grinding, it will present various shortcomings in the bearing operation; The overall quality of the bearing. The bearing is in the fine grinding; because the rough demand is very high; the grinding marks on the exterior of the work can often be observed with the naked eye.
The reason for presenting the traces of the interpenetrating spiral traces is mainly because the flatness of the grinding wheel is poor; there is a concave and convex appearance; during grinding; the grinding wheel and the workpiece are only slightly touched; when the workpiece or the grinding wheel reciprocates several times; The workpiece embodiment will reproduce the interpenetrating spiral and can be observed by the naked eye. The pitch of these spirals is related to the workpiece table speed and the workpiece rotation speed; together with the grinding wheel axis and the worktable rail are not parallel.
(1) The main reason for the composition of the spiral is 1. The grinding wheel is poorly trimmed; the corners are not chamfered; the coolant is not trimmed,
2. The workbench guide guides too much lubricating oil; causing the workbench to float.
3. The machine tool accuracy is not good,
4. Grinding pressure is too large.
(2) The cause of the spiral is composed of 1. The V-shaped guide rail is not rigid enough; when grinding, the grinding wheel is offset; only the edge of the grinding wheel and the touch of the work surface,
2. When the quarrel is repaired, the commutation speed of the workbench is unstable; the precision is not high; the trimming of the grinding wheel is slightly less,
3. The workpiece itself is poorly rigid,
4. The sand on the grinding wheel with broken and too falling off and the iron scraps under the grinding of the workpiece are attached to the outer surface of the grinding wheel; for this purpose, the finished grinding wheel should be washed or washed with cooling water.
5. The dressing of the grinding wheel is not good; there are some bumps, etc. [MechNet]
