为解决我厂从英国引进的数台高精度1212E型专用磨床的润滑用油,我们按其主轴转速2885r/min、主轴间隙0.003mm及其说明书中的要求,并参考有关技术资料,选用了国产2号主轴油试,运转1.5小时即出现抱轴现象,后改用4号主轴油,运转仅3分钟又抱轴了。最后,我们决定自配主轴油,使其技术指标与原用油基本相同,即在37.8℃时,运动粘度为1.7～2.8厘沲,在40℃时,运动粘度为2.2厘沲。起初,先用200号溶剂油和汽轮机油作基础油,用T701、T501、T901和油酸做添加剂,配好后化验运动粘度虽达到了2.2厘沲/40℃,闪点77℃的要求,但试用后仍然失败了,砂轮主轴的传送皮带出现左右滑动,速
To solve the factory imported from the United Kingdom several high-precision 1212E dedicated grinder lubricating oil, according to their spindle speed 2885r / min, spindle clearance 0.003mm and its specification requirements, and with reference to relevant technical information, the selection of domestic 2 spindle oil test, the operation of 1.5 hours that is the axis of the axle, after the switch to the 4 spindle oil, running only 3 minutes and the axle. Finally, we decided to self-align the spindle oil so that it had the same specifications as the original oil, ie kinematic viscosity of 1.7-2.8 centistokes at 37.8 ° C and kinematic viscosity of 2.2 centistokes at 40 ° C. Initially, the first with 200 solvent oil and turbine oil as base oil, with T701, T501, T901 and oleic acid as additives, with a good kinematic viscosity of the test reached 2.2 centistokes / 40 ℃, the flash point of 77 ℃ requirements, However, after the trial still failed, the transmission belt around the wheel spindle slide, speed
