摘要
磨床是应用于零件精加工,尤其是淬硬钢件和高硬度特殊材料精加工的一种机床。近年来由于科学技术的发展,现代机械零件的精度和表面粗糙度要求越来越高,各种硬度材料日益增多,所以磨床的应用越来越广泛。
基于市场对外圆磨床的变速要求高,磨削外圆直径大的要求,经过重新布局和对主轴箱的设计后,M1432A型外圆磨床的加工性能得到了很大的提高,外形更加美观,结构更紧凑,操纵也更方便,更省力。主轴可获得6种转速,磨削直径也增加到了320毫米。这些改变都给操纵工人和维修人员带来方便,基本达到了以人为本的目的。

ABSTRACT
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.
Key words: Cylindrical Grinder; Quenched Steel; Grinding Precision; Finish Machining; Roughness
