中走丝——电火花线切割机床

Hits:2664Publish:2018-04-12

摘要:

  中走丝的属于电火花线切割的一种,电火花线切割加工技术已被广泛应用,并同时显示了其它机床加工方法难以达到的加工手段之一。


  电火花线切割加工的基本原理是利用工具电极对工件进行脉冲放电而实现加工的,电火花线切割加工无需制作成型电极,采用细金属丝(通常叫做电极丝)作为工具电极。脉冲电源的正极接工件,负极接电极丝;电极线以一定的速度往返运动,它不断地进入和离开放电区域;同时在电极丝与工件之间喷入液体介质。操作者只要有效地控制电极丝相对工件运动的速度和轨迹,就能切割出所要求的形状和尺寸的工件。工件运动的轨迹是通过座标工作台(纵横向二台受控制的步进电机)作X、Y向运动而形成的。


  中走丝也是电火花线切割机床的一种,工作原理是利用连续移动的钼丝(称为电极丝)作电极,对工件进行脉冲火花放电蚀除金属、切割成型。其加工工件的质量介于之间所以叫做中走丝,准确的说:中走丝是快走丝的升级产品,可以理解为:能多次切割的快走丝,但它的加工切割速度并不比快走丝慢,反而要高于快走丝,只有在多次切割的过程中才降低切割速度已达到切割的效果,此时计算的是平均效率,并不是最高效率,而加工的质量也趋于慢走丝。走丝速度由系统自动控制,可以根据需要进行调节。
