introduction： High-speed motorized spindle is the core component of high-speed machine tool，The accuracy of each part of the electric spindle unit is usuallyμmlevel，As if jumping1～3μm，The spindle stiffness is generally100-300N/μm，therefore，The precision error and deformation of each part of the electric spindle are very small。however，At high speed，NTNThe bearing generates a lot of heat，Lead toNTNBearing temperature rise is very high，And cause thermal deformation。The error caused by thermal deformation is much greater than the precision error and deformation amount。moreover，The thermal deformation is directly changedNTNPreload condition of bearing，influenceNTNshaft
