我厂在去年试制成功一种精密轴承专用磨床,用来加工精密仪表轴承外圈上的沟道,并参考了国内外有关资料,在该机床上设计了—套利用磁力吸盘来夹持工件的磨削装置,经过试车和鉴定,证明性能良好,使用方便,并可保证达到如下的加工精度:沟道的椭圆度在1微米以内,沟道的壁厚差和沟对基准端面的振摆均在2微米以内,沟道的光洁度▽▽▽8b。如果进一步改进试磨时的条件(如电主轴质量和转速、砂轮
Last year, I plant a successful trial of a precision bearing special grinder, used to process precision instrument bearing outer ring on the channel, and with reference to relevant information at home and abroad, designed on the machine - set of magnetic chuck to grip the workpiece Grinding device, after commissioning and identification, to prove good performance, easy to use, and can ensure the following processing accuracy: channel ovality within 1 micron, the channel wall thickness difference and groove on the reference end of the vibration Within 2 microns, the channel finish ▽▽▽ 8b. If you further improve the test conditions (such as spindle quality and speed, grinding wheel
