On the machine tool bearings, FAG bearings wide range of applications. Machine tool spindle bearings there are certain technical requirements.
1, speed and temperature rise:
With the development of science and technology, machine tool spindle speed high speed increasing the scope, therefore, increasingly high demands on stability of bearing of high-speed operation. Machine tool spindle bearings are important factors for limit bearing speed of temperature rise. Typically, proper selection of FAG bearings type, tolerance class, how it is configured, clearance (preload), lubricant and lubrication method, to a certain extent improve high-speed rolling bearing performance.
2, and bearing service life:
For most machine tools, mainly refers to the life of the spindle components maintain accuracy of spindle use the term and, therefore, requires precision of the bearing to maintain performance meet the requirements of spindle components life. For heavy-duty machine tools or heavy cutting machine tool, you should first consider the carrying capacity of FAG bearings.
3, stiffness and vibration resistance:
To ensure the machine processing quality, must have sufficient rigidity of the spindle system, or a more complex mapping error will occur even flutter. Vibration resistance refers to the ability to resist forced vibration and self-excited vibration. Vibration resistance depending on the spindle and spindle components bearing stiffness and damping. Spindle of preloaded rolling bearing can effectively increase the rigidity of the system.
4, noise:
High speed grinder, grinding head bearing noise is the main ingredient in the overall noise level should use low-noise FAG bearings.
