Is the Shanghai 1350 grinder a hydrostatic guide rail?

Yes. According to the official website of Shanghai Machine Tool Factory Co., Ltd., the MM1350 series precision cylindrical grinder is suitable for grinding the cylindrical surface of cylindrical rotary workpieces with IT6 to IT7 level precision, and is used for single-piece and small-batch production. The grinding wheel spindle is supported by hydrostatic bearings to improve the grinding surface quality. The longitudinal movement of the machine tool table can be driven by hydraulic stepless speed change, and can be driven by a handwheel; the transverse feed of the grinding wheel frame can be hydraulically controlled for micro-automatic periodic feed and rapid advance and retreat, and a handwheel can be used to achieve both coarse and fine feeds.
