High-Precision Electrical Discharge Machining (EDM)

EDM wiring enables intricate, multi-axis profiles and complex tool geometries to be eroded with exceptional linear accuracy and repeatable dimensional control. Utilizing a 0.25mm wire thickness as standard, our CNC wire erosion cell effortlessly achieves pristine surface finishes down to 0.8Ra. This stress-free, non-contact machining process serves as the industry-standard solution for manufacturing miniature components, fragile wall profiles, and intricate form dies that demand micro-tolerances.

Unlike traditional milling cutters or lathes that use physical force to chip away at raw stock, Wire EDM ignores material hardness entirely because the cutting wire never actually touches the workpiece.

Instead, the process relies on thermal energy generated by controlled electrical sparks to erode the metal. This makes it the industry-standard method for machining ultra-hard alloys that would instantly shatter conventional high-speed steel or solid carbide cutting tools.
