目前国内线切割机的运丝方式,一般有单滚筒与双卷丝轮两种。双卷丝轮方式,主要采用机械传动来实现排丝。其运动关系,结构工艺都较复杂,由于阻力大、丝速低、传动精度差等原因,影响机床的加工性能。故不能被广泛采用。 At present, the wire cutting method of domestic wire cutting machine, there are two kinds of single roller and double roll wire wheel. Double roll silk way, the main use of mechanical transmission to achieve the row of silk. The movement, the structure of the process are more complex, due to resistance, low wire speed, poor transmission accuracy and other reasons, affecting machine tool processing performance. It can not be widely adopted.
