Spindle bearing when choosing smooth grease from time to tome what request?

Spindle bearing grease is smooth precision machine tool spindle bearing special smooth oil and similar equipment, it to ensure the accuracy of the spindle to work and to use performance, prolong the using life plays a very important role, is also called the bearing oil. So smooth oil bearing in the choice of the performance request? 1, good smoothness in order to make the main shaft and bearing contact surface between adhere to have an average oil film, and in the spindle start or stop motion impact load of oil film is not destroyed, adhere to the good and smooth performance, play to reduce friction and friction heat, lowering the temperature rise of the main shaft, ensure the machining accuracy, request oil has good smoothness. ( 4) Good rust resistance due to the oil in the working process of the spindle smooth system will not prevent mixed with condensed water or machine cooling fluid in the air, thus the request product has good rustproof, especially in hot and humid climate in the south area, especially to pay more attention to the rust protection. ( 3) Good oxidation resistance of the machine tool main sleeve when using circular smooth way. Request spindle bearing oil used for a long time and the same, will not produce for swimming and infarction oil mud and the bearing clearance, small corrosion effect, thus the request product has good resistance to oxidation stability, our country industry standard request oil oxidation stability index for 1000 h ( ( GB / T, 12581) 。 ( 1) Suitable strength and good temperature characteristics for use to machine the main uranium from high temperature and make the machine tool thermal deformation, bad influence machining precision or make bearing smooth, should be based on the main shaft bearing structure, speed, and bearing clearance to choose a suitable doneness smooth oil well request of oil have good temperature characteristics show concern, avoid the spindle working temperature and environmental temperature change is big, teaching degree changes which affect the smooth performance. Bearing is a kind of important modern machinery and equipment parts. Its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of its movement ( friction coefficient) And ensure that the rotation accuracy. Bearing under high-speed operation needs time to smooth smooth fat is to the right timely smooth such talent guarantee the normal operation of our machines, at the same time also can extend the life of the use of main shaft bearing.
