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。其走丝速度及工件质量介于快走丝和慢走丝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，所以也可以叫：能多次切割的快走丝，所以它的加工速度接近于快走丝，而加工的质量也趋于慢走丝。走丝速度在1～12m/s之间，可以根据需要进行调节。
具备多次切割功能（和慢走丝线切割工作原理相同）,在加工的时候，控制系统将根据编制程序自动调节加工参数（高频的脉宽、脉间、功率管数量及走丝速度），并且，在加工同时也可人为更改加工参数，进行适当调节。
中走丝在保留快速走丝线切割机床结构简单、造价低、工艺效果好、使用过程消耗少等特点的基础上,引用国际上精密模具加工设备的先进理念及慢走丝多次切割技术(即第一次切割用较大的电规准进行高速粗切割,然后用精规准和精微规准进行第二次、第三次甚至第四、五次切割，将加工表面逐级修光,以获得较理想的加工表面质量和加工精度),该机比快走丝更人性化,便捷化,适用范围更广，不仅电极丝移动速度介于“高速”与“低速”之间，而且加工质量高于"高速走丝机",并逼近低速走丝机。所以中走丝给模具行业带了了一个革命，大大改善了原来快走丝加工质量差的弱点，同时很大程度上降低了模具制造的成本！中走丝--快走丝的价格，慢走丝的品质！
China is also a walk Candida WEDM a working principle for the use of mobile thin metal wire (known as the electrode wire) to make electrodes, to carry out work on the pulse spark discharge in addition to metal corrosion, cut into type. Take the wire speed and processing speed in the range of quality silk and silk walking between the so called walk in silk, should also be accurately described as brisk walking several times cut the wire, it belongs to the processing speed of brisk walking close to the wire, and the processing of quality Tends to wire walking. Wire walking speed in the 1 ~ 12m / s, can be adjusted as needed.
Have repeatedly cutting function (go slow and thread the same as cutting), in the process, the control system will be programmed automatic adjustment processing parameters (of the high-frequency pulse width, pulse, power control and the number of wire walking speed), and , In the process but also man-made changes to processing parameters, the proper adjustment.
1The main machine is of cabinet structure. Based on CAD simulated stress strength calculation, we optimize the design for strength enforcement, in order to optimize the static and dynamic mechanic properties of main machine.
2.Adopt ball bearing linear guide to design for X,Y track, superb self lubrication, reduced static friction; we can effectively avoid the crawling of machine.
3.Adopts precision seamless ball and lead screw for movements along X,Y axis.
4.The whole closed machine bed, working table with T shaped groove, pane fixture;
5.Patented designed water-proofidler pulley structure, efficiently improved the service life of idler pulley and the bearing.In taking unilateral discharge wire machine with the processing methods, unilateral discharge process for molybdenum wire to a direction of the discharge, not the reverse, after discharge, this process than by way of three retired two parts of the process better, In one direction only because of its discharge will not cause traces of molybdenum wire (lines).
More than two or three processes, the surface finish on many occasions as cutting because of its processing methods are struck, the existence of discharge particles on the surface, many times since the last cut is the use of small current, slow speed technology, smooth surface, the effect of which close to Wire cutting slower processing of results, instead of walking is ideal for industrial filament. China also take the wire and split into all-in-one
