The present paper deals with the relation between the temperature rise and the thermal deformation of commercially mass produced machining centers in order to develop a methodology to compensate the thermal deformation. It is confirmed by experiments that the ratio of thermal deformation to the temperature rise is almost constant regardless of the differences in the individual machines and the preload condition of the main bearings. The methods are developed to estimate the thermal deformation of the spindle based on the temperature change of the spindle head measured under the transient conditions of temperature rise and fall as well as the steady state, and their validity is confirmed by experimental data.
