Pulse electrode IMI 1.4.1  was machined on a cnc milling machine with an gliding angle of r 0.2, so we had to use a shearing blade r0.2 for machining. The electrode machining is not complicated but requires the machine running optimally to reduce the machining time and also to control the knife wear well, due to the long running time usually 2-4 hours, if it isn't suitable technical process knives are prone to wear. In addition, when running extreme attention, should be taken to the standard base of part and make surface to put jig on the pulse.

In many cases, it is not possible to perform conventional metal cutting, pulse or wire cutting as a solution. In the case of machining where the material is too hard, or when machining forgets to make threading and then heat treatment, or the surface after machining needs roughening, conventional machining can not be handled, must be done on the pulse machine. For pulses to generate pulsed electrodes, the pulse electrode is often deformed like the profile of a pulsed object but symmetric across the discharge surface. At present pulse electrodes are usually made of copper alloy, graphite because these two materials have a high melting temperature, when exposed to electricity discharge is less melted and longer resistant than the object is pulsed.
