Many people have problems with the machine tool spindle. They don't know how to investigate. They just suspect that it is caused by the problem of the machine tool spindle bearing. In fact, the damage to the machine tool spindle is related to many factors. The first is that there are impurities during the installation of the machine tool spindle. During assembly, improper operation by the spindle manufacturer will cause particles to run into the spindle, and the raceway will peel off during high-speed operation. The second is that the machine tool spindle enters water, and some manufacturers work It is relatively bad. The chip liquid is facing the main shaft port of the machine tool during the machining process, which causes the machine to enter the water; the third is that the sealing is not done well, and the rubber gasket is not good; The axial force is different, including the selection of high and low speed and the selection of the cage; the fifth is the cleanliness of the machine tool spindle bearing itself, the manufacturer has not cleaned it, the quality of the grease is not good, and there are impurities; the sixth is the machine tool spindle bearing The precision itself is not enough, and the torque is insufficient; the seventh is that the parameters are wrong in the process of matching the spindle bearings of the machine tool; the eighth is that the manufacturer chooses the assembly paste during the assembly process. With 37 years of pairing experience, bearing pairing is carried out one-to-one according to the actual application scenarios of customers to ensure stable parameters and effectively prolong the service life of machine tool spindle bearings!
