On machine tool bearings; SKF bearings are widely used. Machine tool spindles have certain skill requirements for SKF bearings.
1, speed and temperature rise:
With the development of scientific skills; the spindle speed of the machine tool is getting higher and higher; the shifting scale is getting larger and larger; therefore, the demand for high-speed working stability of the bearing is getting higher and higher. The temperature rise of the spindle of the machine tool is an important factor for restraining the rotational speed of the bearing. Under normal circumstances; correctly select the bearing type, public service level, equipment method, clearance (preload) size, smoothing agent and smooth method; can improve the high-speed function of rolling bearings to a certain extent.
2. Life and carrying capacity:
For the normal machine tool, the life of the spindle component mainly refers to the application period of the spindle accuracy. Therefore, the accuracy of the required bearing adheres to the requirement of the spindle life of the functionally satisfied spindle. Regarding the heavy-duty machine tool or the powerful cutting machine tool; Carrying talent.
3. Stiffness and vibration resistance:
In order to ensure the processing quality of the machine tool; it is necessary to make the spindle system have the rigidity; otherwise, large re-allocation errors and even flutter will occur. Anti-vibration refers to the ability to resist forced vibration and self-excited sensation. The vibration is determined by the stiffness and damping of the main shaft and the bearing. The pre-tightening rolling bearing can be used to effectively improve the rigidity of the spindle system.
4, noise:
In high-speed grinding machines; the noise of the grinding head bearing is the main component of the noise of the whole machine; low-noise rolling bearings should be used.
