WEDM是Wire cut Electrical Discharge Machining的簡(jiǎn)稱,是電火花線切割加工英文簡(jiǎn)寫,電火花線切割加工又稱線切割。其基本工作原理是利用連續(xù)移動(dòng)的細(xì)金屬絲(稱為電極絲)作電極,對(duì)工件進(jìn)行脈沖火花放電蝕除金屬、切割成型。它主要用于加工各種形狀復(fù)雜和精密細(xì)小的工件,例如沖裁模的凸模、凹模、凸凹模、固定板、卸料板等,成形刀具、樣板、電火花成型加工用的金屬電極,各種微細(xì)孔槽、窄縫、任意曲線等,具有加工余量小、加工精度高、生產(chǎn)周期短、制造成本低等突出優(yōu)點(diǎn),已在生產(chǎn)中獲得廣泛的應(yīng)用,目前國(guó)內(nèi)外的電火花線切割機(jī)床已占電加工機(jī)床總數(shù)的60%以上。

電火花線切割分為慢走絲線切割(英文縮寫是慢走絲是 WEDM-LS),快走絲線切割(英文縮寫是快走絲是WEDM-HS),另外還有中國(guó)特有的中走絲(CNC Medium Speed Wire Cut EDM)
WEDM is abbreviated English, WEDM also known as the cut line. The basic 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. It is mainly used for processing a variety of complex shapes and precision small parts, such as the punch Die, Die, Die Bump, fixed panels, boards, such as discharge, forming tool, a model, the EDM processing of the metal electrode , A variety of micro-hole slot, narrow, arbitrary curves, and so on, with a small allowance, high-precision machining, short production cycle, highlighting the advantages of low manufacturing costs, have access to the production of a wide range of applications, the spark at home and abroad WEDM EDM accounts for more than 60% of the total.

低速走絲電火花線切割機(jī)概述
(WEDM-LS),其電極絲作低速單向運(yùn)動(dòng),一般走絲速度低于0.2m/s,電極絲放電后不再使用,工作平穩(wěn)、均勻、抖動(dòng)小、加工質(zhì)量較好,但加工速度較低,是國(guó)外生產(chǎn)和使用的主要機(jī)種。
首先,中走絲、慢走絲、快走絲都是指的電火花線切割機(jī)床。電火花線切割機(jī)(Wire cut Electrical Discharge Machining簡(jiǎn)稱WEDM).
