FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to cutting tools. At spindle shaft running, temperature of every spindle bearing is continuously measured. Thermal strain of bearings is corrected when bearing temperature reaches a definite level at expansion by definite amount with the help of piezo ceramic elements of the width of axial groove made at spindle bore surface.
EFFECT: longer life of bearing assembly.
