초록

Generally, A motor integrated spindle is selected to perform the high speed machining, to improve the machining flexibility, and to simplify the structure of machine tools. The thermal deformation caused by heat generation of the integrated motor is, however, serious problem in motor integrated spindle system. In this study, cooling characteristics for the several kinds of cooling systems(such as, oil-jacket cooling, air cooling) are investigated and more efficient cooling method is presented. The results show that the shaft cooling by the air cooling system is effective to improve the thermal characteristic of motor integrated spindle.
