| Abstract: | To solve the problems that the thermal deformation of the high-grade CNC machine tool has much effect on accuracy and quality of the products,this paper firstly introduces the structure characteristics of the high-speed motorized spindle.Then one type of motorized spindle and supporting structure is selected,and the thermal boundary parameters are calculated.Much more the static and transient temperature field are simulated by using FEA software ANSYS in one working condition.At last,the main measures to im... |
