★    步进电机剪线方式是通过步进电机直接驱动剪刀连杆，在剪线时配合主轴的角度完成剪线动作。通过控制步进电机的驱动运动曲线代替剪线凸轮的运动曲线即电子凸轮的效果。相比传统电磁铁剪线方式有剪线效率高，噪声低；机械结构大大简化，维修调试更加方便；剪线效果不受主轴转速影响等诸多优点。

Stepping motor thread trimming method is to use stepping motor to drive the cutter rod directly and then finish the trimming action by coordinating with the angle of the main shaft. The control of the drive motion curve of the stepping motor has replaced that of the motion curve of trimming cam or electronic cam. Compared with traditional trimming mode with solenoid, the efficiency is higher and the noise is lower; the mechanical structure becomes simpler and the maintenance and adjustment becomes more convenient; and the trimming effect will

not be influenced by the main shaft rotation speed.
