摘　　要：在加工长不锈钢管过程中磁场发生器温升较大,超过绕组的允许温度,导致磁性珩磨加工受到限制。为保证加工的可持续性,本文提出了外循环水冷的冷却方法,并通过仿真分析最终得到该系统稳态温度分布云图。磨削试验结果表明:水冷方法可减小系统温升,提高系统的加工稳定性;磨削试验稳态温度与仿真稳态温度的误差在允许范围内,验证了仿真模型的可靠性。Led to the limitation of magnetic honing process, the temperature of the magnetic field generator caused in machining long stainless steel tube rose fast and higher than allowable temperature of the winding. To ensure the process continuousness, the external circulation water cooling method was proposed, and the cloud map of steady state temperature distribution was achieved by simulation analysis. The result shows that water cooling can restrict the system temperature and improve the machining stability. The errors of the steady state temperature in grinding test and simulation are within permission, the reliability of the simulation model are verified.
