Grinder is a machine which is widely used in finish processing of the part , especially for the hard steel and the finish machining of the high rigidity special materials. In recent years, with the development of the technology, the need for machine’s precision and surface roughness is getting higher and higher. At the same time, the high rigidity materials are manifold, so the grinder machine is used more widely now.
Based on the high demand for cylindrical grinder and the bigger diameter of the grind circularity, the performance of M1432A cylindrical grinder has gained a prodigious improvement after renewing the layout and designing the headstock. The machine now has the features of perfect, compact, convenient and labor saving. The principal axle can provide six rotation speeds, and the diameter has also increased to 320 millimeter. All of these changes has brought more and more convenient for the manipulators and the maintaining workers. So the changes have achieved the goal of center on human.
