原文 Commonly used grinding machine As a kind of important ultra-precision processing method，the advantage of grinding is high machining accuracy, processing materials range, almost suitable for all kinds of materials processing, grinding can get very high precision and shape accuracy, even can reach the limit, the machining accuracy of grinding device is simple, does not need a lot of the complex mechanical and not demanding equipment precision conditions. As a super finishing one method, grinding machine is mainly used for the high precision grinding workpiece plane, the surface of cylindrical workpieces both inside and outside, tapered face inside, sphere, thread face and other type surface. Its main types have dise-type grinding machine, shaft type grinding machine, magnetic grinding machine and all kinds of special grinding machine. Dise-type grinding machine points single plate and double-tray two to double-tray grinding machine used the most common. In double-tray polishing machine, multiple workpiece and into the mill plate, located on the cage between inside, maintain frame and workpiece drives by eccentric or planet of plane parallel movement. The mill rotating, the parallel with the grinding plate can not turn, or with grinding plate under negative spin, and can move to pressure workpiece (pressure adjustable). In addition, with the grinding plate can also turning round pillar rocker to Angle, unloading workpieces. Double-tray grinding machine is mainly used for processing two parallel planes, a plane (two pressure should be increased to the workpiece accessorie), outside YuanZhuMian and sphere (with belt v-shaped slot grinding plate), etc. YuanZhuMian, because the processing and workpiece to both sliding, shall be reasonable choose to keep rolling type and arrangement plane slots Angle. Only a single plate grinding machine, used for grinding plate under the grind workpiece under plane, can make the different shapes and sizes with plate processing, grindin
