【正文】 process This will help to improve the grinding effect of the requirements to achieve parallelism. Rotary Shaft with its extensive use of internal and external processing and tool grinder grinder. Processing the first frame and the top is equivalent to bus, if the question of the existence of beating, processing of the workpiece from the same problem will affect the quality of parts, so do a good job before processing the first frame and the top of the testing. Hole for grinding, the coolant water to the full access to the grinding position, in order to facilitate the smooth discharge grinding. Processing of thinwalled shaft parts, the best use of technology gripping units, clamping force can not be too large, otherwise easy to produce in the workpiece circumference within the Triangle deformation. Surface Treatment and Distribution Group Parts surface marks left behind in the processing, is the stress concentration wear area of concern was the source of crack propagation, so after the end of processing, the need for parts for surface hardening, grinding through the fitter to deal with outprocessing problems. Some of the workpiece edge, an acute angle, orifice down to a blunt, R of. In general, the electrical processing of the surface will have about 610μm deterioration of hardened layer, the color was gray, brittle and hardened layer with residual stresses, prior to the use of full elimination of hardened layer, the method of surface polishing, grinding hardened layer removed. In grinding, EDM process, the workpiece must be magnetized, with a weak magnetic force, is very easy for sorption of small things, so in prior to assembly, to the workpiece for demagnetization processing, and cleaning the surface o
