The main component that comprises a machine tool is component of machine tool main shaft, main shaft component also is the drive that goes up in main shaft by main shaft, bearing, installation be combined with a few fastener and become. Whether it can work normally have very big effect to increasing the quality of workpiece and manufacturing efficiency, among them bearing is the largest to influence of function of main shaft component part. Well-known, the precision of machine tool bearing, quality is the crucial factor that affects performance of machine tool main shaft. To how defining the accuracy class of an accurate bearing, ISO/ABEC (the committee of annular bearing project that ABEC belongs to for place of American bearing production association) the width common difference that defined group of inside and outside only, circularity, verticality, taper, axial beats and radial beats. And want to make machine tool main shaft implementation high accuracy, can high rate, tall stiffness and low vibration, low hectic demand, need pair of bearing itself more parameter undertake controlling. Before leave factory, exceed precise role to contact ball bearing to want to experiment through 100 percent function, through digital vibration filter wave analyses precise to exceeding role to contact ball bearing to undertake experimenting detecting, ensure bearing character and applied function. All test result is but retroactive. Cleanness is spent (Cleanliness) cleanness of 　 　 　 is spent crucial to accurate bearing product, XEZ exceeds accurate bearing component to want to clean 3h with multistage dissolvent commonly, avoid bearing of foreign matter interfuse thereby, prevent immanent contaminative cause. Additional, even the surface of blame job sex of grinding bearing, make sure bearing does not have foreign matter before leave factory. Consequently, bearing product of production can increase a machine tool normal movement time. Cage (Cage) cage of 　 　 　 is very crucial to machine tool bearing, the function of cage can affect the stability that machine tool bearing rotates in high speed. Standard cage of production uses data of phenolic aldehyde colophony, interior design and the public errand of clearance wrapping up aperture are tightened and control guiding surface, make sure cage is in high speed movement, lubricant reach dynamic when of stability best.
