Miniature bearing grinding process analysis

1 in the early stages of the first few times the wheels in the radial feed, due to the flexibility of the process system form, the actual shape of the depth of the smaller than to c product in radial feeding process systematic difference, meaning long 2 at this stage. With the increase of number of stable phase beginning with radial into bed, artifacts, jig process system of intercourse form as it also increases by fault. Straight first connect process system of radial force of the system, the elastic deformation resistance is equal to the actual depth is equal to the radial feed, at this point is stable stage. 3. Light grinding stage due to the elastic deformation of technological system is gradually restored, the actual radial feeding is not zero, surface were reduced by south 0 l in the early stage and stable stage light stage in figure 1. 13 just process the application of law of grinding mill: at the start of grinding, the larger the radial feeding, early compression and stable stage, in order to improve production efficiency. Increase light grinding time appropriately, can better improve the quality of the surface of the workpiece. 2. Three of the characteristics of grinding grinding characteristics are as follows: (1) irregular cutting edges. Abrasive the size, shape and distribution of all in the irregular random state. (2) cutting thickness thin, high machining accuracy. Cutting thickness is usually only a few microns (3) high grinding speed, high temperature. Ordinary tool cutting speed under 200 m/min, and left and right sides, such as grinding speed of 35 m3 is even higher. This high speed produces surface caused by the high number of calories burned. (1) grinding is wide. Can be processing a variety of surface and a variety of materials, especially high hardness difficult cutting materials second round have self-sharpening effect, make the grain at a relatively sharp column mouth to cutting the workpiece.
