Wire cutting, as the name implies, is through copper or molybdenum wire (this wire is often called "silk" because it is usually very thin). Power supply, electric spark generated by current moment, to achieve high temperature, the melt metal near the "silk" area, corrosion, so that the fracture of a metal processing technology, this technology is way less century 60 s, the former Soviet union people invented, and applied to the industry starts from the our country, and he is the predecessor of the edm machine.

Generally speaking, we put it is the silk machine, silk machine is generally divided into fast silk, slow silk and silk, their biggest difference is that the speed of cutting materials is not the same, another can be the use of "silk" is not the same.

General fast wire or wire is mostly used in molybdenum wire, wire walking most used copper wire, there will be a little difference between the conductivity of the two kinds of wire, cutting out the accuracy and surface roughness is different, generally speaking, slow wire cutting realize from the workpiece cutting position to go several times, for the first time to cut a seam, but end don't cut off, We can do it again or several times, called cut one repair three or cut two repair five, we need to wear wire before wire cutting, we will first use the way of discharge to punch a wire hole.

Line generally need to cut in this process, can be used to cut the blind holes, nor can be used to cut pit, and this is one of the conditions, the second condition is that the cutting of the hole must be and cut surface vertical, or can cut a little Angle, but you have to thread cutting Angle large bell, requires people to do some adjust, The Angle is too large to use the live line cutting process.
