Sinker EDM Tube Fabrication
Vita Needle utilizes Electrical Discharge Machining, otherwise known as EDM or spark machining, as one method to fabricate burr free cut to length tube parts. In addition to cut and deburred tubes, Vita relies on EDM to fabricate features on tubes, ranging from simple slots and angled cuts to holes, patterns, contours, skives, complex shapes and other unique geometries. Fabricating tubing using sinker EDM tube fabrication is a CNC process. A program is generated which drives the wire (or sinker electrode) along the designated tool path, and the resulting high frequency electrical discharges between the workpiece and the electrode erodes the specified path.
Because EDM can work with any electrically conductive material (including stainless steel or any of our high nickel alloy offerings), it is perfect for fabricating all types of tubing that Vita Needle sells. EDM allows Vita to quote fast lead times on highly demanding designs with challenging tolerances. Combined with traditional machining techniques and other capabilities, EDM technology greatly enhances the overall tube fabrication capabilities that Vita Needle can offer. Through research and development, Vita Needle has recently pushed limits for Wire EDM tube machining capabilities---to the point where EDM can effectively replace grinding for some applications! Length and size allowing, Vita can hold ±.001" overall length in some cases.
Post Fabrication Processes
Many customers request long lengths to be cut and deburred prior to shipping. With perpendicular cut ends and clean material, the wire or tubing can be put right into production or into stock. Some customers even require sharp ends on cut pieces of electrical discharge machining tube for welding applications. All parts that are cut go through standard ultrasonic cleaning, including products up to 72" long. Other post fabrication processes available can include: electropolish, passivation, tumbling for edge breaks, sand blasting, and additional forming (bend, coil, etc.).
