What Are The Different Types Of EDM Machines?
• This process utilizes an electrically conductive wire primarily made of brass to cut holes or contours that extend completely through a workpiece • Best Uses: Holes, Tapered Surfaces, Die Openings, Gears, Plastic Mold Components and High Precision Machined Parts • Tolerance: 60 millionth contour accuracy can be attained under optimum conditions with our equipment • Surface Finishes Achieved can be as low as a measurable .1 Ra (3-4 RMS). However, surface finish varies based upon material type, wire diameter and material thickness. Our best finish attainable is what we’ve described and it can be reached on a fairly substantial number of material and thickness combinations. CNC Ram EDM • Utilizes an electrically conductive electrode to erode a cavity to depth and size • Tolerance: .0002 can be attained on a part to part basis under optimum conditions with our equipment • Surface Finish: as low as .2 Ra (8 RMS) but please see the notes above Hole Popper EDM • Utilizes an electrically con
