Motorized Spindle

To solve the problems that the thermal deformation of the High-Grade CNC machine tool has much effect on accuracy and quality of the produces, the structure characteristics of the high speed motorized spindle is firstly introduced in this paper. Then one type of motorized spindle and supporting structure are 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 improve the uneven temperature field and the plans to reduce the thermal deformation are put forward, which are provided some technical bases for the equipment to achieve the high-speed and high-precision machining.
