SPZ-1静压轴承内圆磨具(以下简称内圆磨具)是洛阳轴承研究所与上海滚动轴承厂的一项科研成果,它具有主轴回转精度高、寿命长、油膜吸振性能好等一系列优点。我们采用了这一先进技术代替现有的滚动轴承内圆磨具用于M2110内圆磨床。但在制作和调试过程中出现了一点问题,即内圆磨具在停车时如抽油泵立即停止抽油,从蓄能器排出的压力油会大量从前盖端部溢出,影响正常使用;另外,该内圆磨具的前盖系采用离心浇铸铜整体式结构不易制作,难以达到图纸要求,影响了内圆磨具的性能。根据这些情况,我们通过分析研究,反复试验,摸索出了一些规律,克服了内圆磨具停车时前
SPZ-1 hydrostatic bearing internal circular grinding (hereinafter referred to as the internal circular grinding) is a research institute of Luoyang Bearing and Shanghai Rolling Bearing Factory, which has a spindle rotation precision, long life, good film vibration absorption performance and a series of advantage. We use this advanced technology to replace the existing roller bearing internal circular grinding machine for M2110 internal grinder. But in the production and commissioning process a little problem, that is, when the internal grinding wheel stop pumping oil pump immediately stop pumping oil from the accumulator will be a large number of pressure oil overflow from the front cover, affecting the normal use; In addition, The internal circular grinder front cover system using centrifugal casting copper monolithic structure is not easy to produce, difficult to meet the requirements of the drawings, affecting the performance of the internal circular grinding. According to these circumstances, we through the analysis of research, trial and error, worked out some laws to overcome the internal friction tool before parking
