An Analysis of the Thermal Characteristic according to the Cooling Method of the High Speed Spindle Housing

고속 주축 하우징의 냉각방식에 따른 열특성 해석

High speed machining is the core technology that influences the performance of machine tools, and the high speed motor spindle is widely used fur the high speed machine tools recently. The important problem in this spindle is to reduce and minimize the thermal effect by motor and bearing. In this study, the analysis of thermal characteristic of spindle is performed according to the cooling methods of housing by using finite element method. This result can be applied to the design and manufacture of the high speed spindle.
