Milling mill use has greatly increased the degree of mechanization of kibble leveling process. However, due to the accuracy of the machine itself, as well as grinding wheels, grinding amount, feed rate, coolant, and many other factors affect the roughing the optical parts of finish is generally only reach 220 to # 240 to # sand surface. Domestic kibble plane generally use the granularity of the grinding wheel between the JR60 ~ # ~ 100 ~ #, the concentration of 100%. Kibble completion requirements of the parts surface finish level generally ▽ 6. View from the our kibble plane features, generally to remove a larger allowance, single-sided margin of more than 2 to 3 mm, and some parts grinding the first side when the rest of the amount as high as more than 5 mm . This will require that the diamond grinding wheel with a good grinding performance, is the grinding wheel should be used bronze binder and coarse granularity should. Practice has proved that the particle size in the 80 ~ # 100 to # of the grinding wheel due to its small grinding force for PM5 Keywords: optical, parts milling, mill surface finish grade line, speed vacuum consolidation process, level governor 前 言 作为一名光电系的学生,工艺设
