Abstract


In order to improve the grinding efficiency , ensure parallelism of the workpiece on the basis of research and analysis of the traditional two - sided grinding process , the design of a high-speed grinder abrasive sided fixation and its auxiliary device and machine parts strength check and stiffness of checking the accuracy of the spindle system analysis, design of the machine 's pneumatic system , electrical system and spindle speed control system . Through experiments on the processing quality of the double-sided high speed grinding machines , machining accuracy, efficiency , and processing costs were tested. Machining surface roughness of Ra0.88nm; flatness of 0.07μm ( RMS ) , parallel degree of 0.01mm , and the processing efficiency is improved by 30 to 100 times the abrasive cost is reduced by 60% . And select the method of grinding parameters are given based on the experimental results . Experimental results show that the paper developed machining accuracy has reached the level of processing of nanoscale .
