Bearing surface grinding disadvantages and countermeasures summary: Dongfeng Motor Corporation strongly launched the first domestic double-column CNC vertical car Senladili CombiEdge cross-shaped bearing blade to correctly understand the lean coating of China's tool coating data soft coating seminar Siemens SINUMERIK The use of domestic CNC machine tools in the middle of new compound processing will seize the proportion of imported machine tools and key occupations. Japan's Fujitsu new drills will complete the high-precision drilling plane grinder trend to the forming mill. Xuzhou hydraulic parts factory and other thrust double-stage hydraulic cylinders are exported to Vietnam. T-Rail interface for successful profile turning Multi-axis control for high-speed machining Intermediate processing of composite materials. New tools for DLC coated tools. Machining parts in the middle of machining. Virtual reality skills in urban design. Top-of-the-line hydraulic machine mainframe window size computer clamp tool single screw anti-loose wedge and anti-loose fine-tuning layout AutoCAD optimization system approach is the number of synchronous motor poles? NTN announced that the bearing with the resolution of the original 40 times the rotation sensor [tag: tag] bearing in the grinding process; its work appearance is ground by a high-speed rotating grinding wheel; therefore, if the grinding does not press the job The instructions operate and adjust the equipment; it will present various shortcomings in the bearing operation; it will affect the overall quality of the bearing. The bearing is in fine grinding; because the rough demand is high; the grinding marks on the exterior of the work can often be observed with the naked eye. To its table.
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 the broken and too falling off and the iron scrap 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 rinsed with cooling water.
5. The dressing of the grinding wheel is not good; there are some bumps.
