一、绪言磨床主轴轴承是影响磨床加工精度、光洁度及效率的一个重要因素,素有“心脏”、“灵魂”之称。为了制造精密磨床,上海机床厂从五十年代后期起在国内首先开展静压技术的研究及应用,先后在四十余个品种的各类精密、大型磨床上应用具有自己特色的各类静压支承,体现出静压支承的高精度,高刚度及长寿命等的一系列优点。对提高产品质量起了积极的作用,取得良好的成效。七十年代后期又率先推出多油楔阶梯动静压轴承(DYNASTAT轴承),目前已形成HSDB-1(无外节流)及HSDB-R(有外节流)两个系列。使轴承的性能有了进一步提高。也使磨床的加工精度、效率、光洁度有了
I. INTRODUCTION GRINDING Spindle bearings are an important factor affecting the machining accuracy, finish and efficiency of grinding machines. They are called “heart” and “soul”. In order to manufacture precision grinding machines, Shanghai Machine Tool Plant started the research and application of static pressure technology in China from the late 1950s. It has applied various types of static pressure with its own characteristics on more than 40 varieties of various types of precision and large-scale grinding machines Support, reflects the hydrostatic support of high precision, high stiffness and long life and a series of advantages. To improve product quality has played a positive role, and achieved good results. In the late seventies and the first to introduce multi-wedge step hydrostatic bearings (DYNASTAT bearings), has formed HSDB-1 (without external flow) and HSDB-R (external throttle) two series. The bearing performance has been further improved. Also make the grinding machine processing accuracy, efficiency, finish there
