【正文】 tools. Finishing grinding grinding to strictly control the deformation and grinding cracks, even very small cracks, in the followup processing will be exposed in use. Therefore, the grinding of feed to small, not large, the cooling fluid to the full, dimensional tolerances of the parts in less than to minimize the grinding temperature. Appropriate when the choice of a good grinding of the grinding wheel is very important, tool steel for highvanadium highmolybdenum status, choice of GD pared the application of singlecrystal corundum grinding wheel, when processing hard alloy, high hardness of the material hardening priority organic bonded agent of the diamond grinding wheel, grinding wheel since the organic binder sharpened good磨出rough up the workpiece Ra = . Grinding, it is necessary to pay attention to the timely finishing grinding wheel, grinding wheel to maintain a sharp, when the grinding wheel after passivation will slip surface rubbing, squeezing, resulting in surface burns, lower intensity. Sheet metal parts used in processing the majority of surface grinding machine processing, processing of the Central Standing Committee met in a long, thin sheet metal parts, such parts of the process more difficult. Because the processing at the role of magnetic adsorption, the workpiece deformation produced, close to the surface of the table, when the won the workpiece, the workpiece will have a back deformation, thickness measurement, but fail parallelism, the solution can be separated from the magnetic grinding method, grinding pad when the contour in the workpiece the following block, block all抵死, processing, feed small, multiknife, a good side processing, you can no longer block pad contour, direct adsorption
