3MZ1310A内沟磨床的砂轮轴采用动压轴承支承。由于该动压轴承油箱体积小，使工作时油温升高，粘度降低，油楔刚度发生变化，造成磨削精度不稳定甚至抱轴现象。针对以上问题，对供油系统进行了改造，加大了油箱体积，延长了润滑油流动路线，加快了润滑油的流动速度，使润滑油工作温度恢复正常，解决了存在的问题，经改造后加工出的产品尺寸精度稳定在0.003mm以内。
3MZ1310A內溝磨床的砂輪軸採用動壓軸承支承。由于該動壓軸承油箱體積小，使工作時油溫升高，粘度降低，油楔剛度髮生變化，造成磨削精度不穩定甚至抱軸現象。針對以上問題，對供油繫統進行瞭改造，加大瞭油箱體積，延長瞭潤滑油流動路線，加快瞭潤滑油的流動速度，使潤滑油工作溫度恢複正常，解決瞭存在的問題，經改造後加工齣的產品呎吋精度穩定在0.003mm以內。

3MZ1310A inner groove grinder grinding wheel shaft is supported by dynamic pressure bearing whose oil tank volume is small. The increased oil temperature and decreased oil viscosity during working result in the change of oil wedge rigidity, unstability of grinding precision and even the shaft not rotation. Aiming at the above problem, the oil supply system is developed by increasing the volume of oil tank, prolonging running line of lubricant , accelerating the running speed of lubricant, and lowing the oil temperature to normal level. The existing problem is resolved. The product dimensions are stabled within 0.003mm after the modiifcation.
