内圆磨具是轴承内表面磨床的关键部件,它的性能好坏,直接影响工件的磨削精度,特别其主轴轴承对磨削效界影响极大。但目前我国轴承行业极大多数还使用滚动轴承皮带轮拖动机械磨头和电子轴磨头。这些磨具砂轮线速度低,刚性差、寿命短、轴承维修选择和装配要求较高,是轴承磨床的薄弱环节之一。由于液体静压轴承具有吸振性强、刚性好、摩擦系数小、回转精度高等优点,近几年来,轴承行业也日益增多地被采用。这次我厂和上海机配公司磨床设计组、洛阳轴承研究所等单位,经过共同努力,初步研制成功静压轴承电子变 Internal circular grinding machine is a key component of the inner surface of the bearing grinder, its performance is good or bad, directly affect the grinding accuracy of the workpiece, in particular, its spindle bearing greatly affect the grinding efficiency. However, the vast majority of bearing industry in China now also use the roller bearing pulley drag mechanical grinding head and shaft grinding. These abrasive wheel linear speed low, poor rigidity, short life, bearing repair selection and assembly requirements, is one of the weak links bearing grinder. As hydrostatic bearings with strong vibration absorption, good rigidity, low coefficient of friction, high precision rotary bearings, the bearing industry is also increasingly being used in recent years. This time I plant and Shanghai Machine with the company grinder design team, Luoyang Bearing Institute and other units, through joint efforts, the initial success of the hydrostatic bearing electronic variable
