Search this category by sizeElectrodes and EDM tips are the wear parts that conduct electrical current to the workpiece in spot/resistance welding, MIG welding, stud welding and die-sinking EDM machines. They are used heavily in automotive, appliance, mold-making and general metalworking. This category holds 14 families and 133 part types: spot welding electrode tips, welding pins, MIG contact tips, electrode holder pins, copper-tip electrodes, stud welding electrodes, conical spot electrodes, stepped EDM electrode tips, drilled tubular electrodes, tapered small-hole electrode tips, threaded and hex-body electrodes, plus small-hole EDM guide bushings and contact bushings. We machine steel, stainless steel, brass and aluminium; copper and copper alloys are preferred for the electrode tip itself. Parts are turned on the Goodway SW-20 Swiss lathe within a ⌀1–20 mm range at h6/H7 fits; ±0.01 mm is targeted on critical diameters. Alongside the 133 catalogue types, we produce custom sizes to your technical drawing. Send a sample or drawing and we will quote by dimension and quantity.
The defining part here is ELEB-TUB-03 at L/D 13.3 — the slenderness a sliding-head lathe is built for. Lengths across the 133 variants run 16–140 mm, the longest being ELEB-TUB-18 at 140 mm, still inside the 207 mm single-setup limit. Operations: 48× thread turning, 22× hex flat milling, 58× axial bore, 45× taper turning, 19× knurling.
103 of the 133 variants reference a DIN or ISO standard; the tolerance classes in use are 6g, H6, H7, h6, h7, h9.
Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.
Frequently Asked Questions
EDM electrode tips are turned in a single operation on the Goodway SW-20 Swiss lathe to the diameters, steps and tapers in your drawing. Copper or copper alloy is usually used; on small-hole and stepped geometries, ±0.01 mm is targeted on critical diameters. Surface finish and concentricity tolerances can be measured and reported on request.
Steel, stainless steel, brass and aluminium are machined as standard. Because electrodes and EDM tips require conductivity, copper and copper alloys are the usual choice. We can select the material together based on the application (spot, MIG, stud, EDM) and the mating workpiece.
Standard fits are held to h6/H7 class; ±0.01 mm is targeted on critical diameters. Concentricity and squareness tolerances for tapered tips, small holes and steps are held to the drawing. Measurement results are provided with an inspection report on request.
Beyond the 133 catalogue types, we manufacture custom electrode and EDM tips to your drawing or sample. Swiss-lathe production suits both prototype/sample quantities and series production; we state the best production plan for your quantity and size in the quote.
Pricing is by quotation; no fixed figures appear on the site. Send the technical drawing, dimensions and quantity and we will share a size-specific quote and lead time. We have manufactured in Düzce, Turkey since 2009 and serve both domestic and export orders.
