Tube Electrode (Bored)
Tube electrode with central flushing bore for fast-hole EDM drilling.
Manufacturing Scope
Tube Electrode (Bored) is a Electrodes & EDM Tips family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀3–18 mm, lengths 40–140 mm, standard material Brass (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀18 mm bar stock; its longest variant is ELEB-TUB-18 at 140 mm. Besides turning, the family requires axial drilling (⌀1–8 mm). All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is ELEB-TUB-03: 40 mm long at ⌀3 mm, a length-to-diameter ratio of 13.3. This ratio is the very reason sliding-head lathes exist. The guide bushing supports the bar immediately beside the cutting point, so there is no deflection; the same part chatters and drifts in diameter on a conventional lathe.
Variants are machined to h7 tolerance; the smallest is ELEB-TUB-03 (⌀3 mm) and the largest ELEB-TUB-18 (⌀18 mm). The family includes bored variants. Custom sizes, tolerances or materials are produced to the part code on request.
