Cut of electric spark line machines power source to should choose the need that machines a condition to satisfy, numerical control electric spark walks along treatment of machine of silk thread cut quickly to be like next requirements to pulse power source: One, electrode silk loss is small silk of the electrode in be being machined is used repeatedly, loss affects precision directly, increase fracture of wire at the same time. Because this high speed walks along silk to want to have,make electrode silk uses up small function, manage long stable treatment in order to make sure certain treatment precision is mixed. 2, numerical control electric spark walks along short circuit of silk thread cut quickly electric current of sharp edge value has certain adjusting range to want adjustable. 3, the parameter such as pulse width and pulse interval has certain conditional limits. Machine conditional make choice of when the basis after electric current of sharp edge road, can reduce pulse width, width small discharge is short, discharge capacity is small, discharge indentation is small, be helpful for surface roughness reducing. Cannot too small, machine otherwise cannot undertake, width is inside limits. 4, the edge after the forward position of pulse form is mixed wants steep, if forward position is not steep, criterion vaporization *** force is not powerful, treatment surface roughness is inhomogenous. But around accelerates electrode silk to use up along steep meeting, should consider electrode silk to use up so with coarse two index. CNC Milling
