The common faults in the machine tool spindle bearing operation precautions

Need before checking surface cleaning machine, and then remove the perimeter of the machine tool spindle bearing parts. Oil seal is very fragile parts, the need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if the present adverse symptoms, be sure to replace the bad oil seal will cause the damage of the bearing and severe equipment downtime. Check the lubricant, with little lubricant in friction between two fingers, and if the presence of pollutants, can feel that, or in the back with a thin layer of lubricant, then seal of inspection. Replacement of lubricants, oil lubrication of machine tool spindle bearings after xie used engine oil, oil impregnated with fresh and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, then spilled oil in addition to these, the oil before use it's best to filter it. 1, the choice of grease: the choice of grease is generally based on the speed of the spindle bearing, heat resistance, noise requirements and choose starting torque, etc, for the performance of various oil is very understanding. 2, the choice of bearing seal type: spindle bearing lubrication can be divided into oil lubrication and grease lubrication. Oil lubricated bearing is generally choose form of bearing, grease lubricated bearing dust cover is generally selected or rubber seal seal. Dust cover suitable for high temperature or the use of good parts, seal two points contact seal and non-contact seal and contact seal dustproof performance is good but the starting torque, the sealing type starting torque is small, but there is no contact sealing performance is good. 3, bearing type selection, bearing type are generally according to the product of form a complete set of conditions of use and the load of machine tool spindle bearing. So you have to learn the user's actual load is consistent with the selected bearing, if bearing can not meet the use requirements, should change model as soon as possible, but unless special products on the choice models generally do not have what problem.
