Electrical Discharge Machining or EDM is a non traditional method of removing metal by a series of rapidly reoccurring electric pulses which are discharged between an electrode and the work piece.
Why Wire EDM?
Wire EDM is an ideal process for prototyping and production runs of 1 to 50,000 pieces because it requires no wait for expensive tooling to be built. We have the software to translate virtually every type of CAD file and can program your design into the machine and put it into production immediately.
Why Sinker EDM?
Sinker EDM is an ideal process for non conventional machining, tough or hardened tool steel, exotic metals, blind cavities, slots, which are located in areas of which are un-accessible with the conventional machine while achieving a higher finish. Hardened steel and exotic alloys pose little or no additional challenge over softer work pieces.
EDM Advantages
- Intricate & complex details are possible
- Internal corners down to R .001" [.025mm]
- Small features down to .004" [.10mm]
- Extremely hard work pieces can be cut
- Very high accuracy attainable
- Precise control of surface finish
- No cutting forces
- Virtually no geometric limitations
- Non conductive work piece’s cannot be cut
- Slower material removal rate than milling
- An electrode is required [Sinker EDM]
- Cavity impressions for molds
- Core ribbing details for molds
- Raised or depressed engravings
- Extrusion or punch die profiles
- Pockets with square or sharp corners
- Narrow (.012”) kerf thru cuts
- Narrow (.005”) kerf thru cuts
- Slots, keyways, square & hex drives
- Gears, splines
- Small or deep holes, especially in hardened
- Removal of broken taps and drills
- Hard tapping
- Machining of carbide
- Application of textured surface finish
