Product Name
Model SD-1M
Series EDM (Electrical Discharge Machine)
Product Description


ㆍHigh drilling performance through any conductive material in cluding tungsten carbide, hardened steel, iron, copper and brass.
ㆍThe SD-1M opens small holes using hollow copper electrode diameter from Ø0.08mm to 4.0mm a high speed. (Maximum machining rate of 100mm/min.)
ㆍWith extremely low electrode wear(5~20%) in low wear machining, SD-1M delivers overwhelming cost effectiveness when compared to similar machines.
ㆍ0.00004˝(0.001mm) DRO resolution (Option).
ㆍVersatile, swiveling and swing head can easily open angled holes on flat, spherical and curved surfaces. It also works on work piece that is too large to be clamped on the worktable.
ㆍThe SD-1M provides an EDM machining operation with EDM oil, graphite solution and tap water etc. as dielectric fluids.
ㆍInch/metric conversion.
ㆍNEW - Electrode retraction value set function. Electrode change positioning function. 
ㆍAuto drill depth value compensation.
