摘要
介绍了直线电机在数控铣床上的应用方案、工作原理和基本实现方法。用直线电机代替X轴、Y轴滚珠丝杠和伺服电机,采用高速电主轴和刀库,并用光栅尺作为反馈单元,实现全闭环控制,改善了数控机床进给速度和加速度,提高了加工精度和效率;对铣床滑台进行优化,减轻运动部件质量,加强机床刚性,提高了高速高加速运动下的抗冲击性。
The application of the linear motor in the NC milling machine was studied. Through applying the linear motor instead of the servomotor and screw rail, the precision and efficiency of the NC milling machine was improved. A new worktable was designed to reduce its weight and increase the rigidity of the machine.
