Many small partners are always worried that the precision machine tool spindle bearings purchased are not wear-resistant and have a short service life? In fact, precision machine tool manufacturers and excellent bearing manufacturers can effectively improve the service life of bearings if they do this well. Do you know what it is? The answer is the heat treatment process! Heat treatment is a relatively special processing technology, and it is a very important link in the production of bearing grinding. Good bearing manufacturers have their own mature heat treatment process. If the heat treatment is not in place, the damage will be very large. First of all, the first point is that the temperature is too high or the heating time is too long during heat treatment, resulting in overheating. At this time, the brittleness of the processed bearing ring increases, and the load it can withstand will decrease, which will easily lead to cracking of the bearing and seriously affect the use of the bearing. Longevity! Therefore, during heat treatment, the quenching heating temperature and holding time should be correctly selected, and the instruments and thermocouples should be checked regularly to prevent overheating due to out-of-control instruments! Only when the torque is accurate can the rotation be stable. 38 years of professional production of precision spindle bearings!
