FIELD: process engineering.
SUBSTANCE: proposed method comprises fitting the spindle in machine spindle assy housing and clamping by flange to run in front and rear bearing assemblies. Note here that channels are made in said housing and flange to coo down spindle assy elements. To increase service life, temperature is additionally controlled by temperature transducers arranged nearby bearing outer races. Vibration is controlled by vibration gage arranged in the housing nearby spindle front bearing assy. Spindle axial displacement is controlled by appropriate pickup arranged at spindle front end. Readings of said transducers are used to cur off drive motor in due time in case allowable load falls beyond tolerances.
EFFECT: longer life.
