Wire EDM
Wire-cut EDM for blade tooth profiles, tear-notch dies and intricate punch shapes — accuracy down to ±10 µm.
- 0.25 mm and 0.30 mm brass wire on Sodick / Mitsubishi clones
- Cuts hardened tool steel (D2, M2, HSS, A2) without de-tempering
- Profile accuracy ±10 µm, surface Ra 0.8–1.2
- 4-pass finishing routine for tear-notch dies
Wire EDM is the heart of the blade shop. Tooth profiles on every zigzag, V-cut and perforation blade we ship are wire-cut after heat treatment — that’s how we hold a sharp tooth tip on D2 hardened to HRC 60. Pre-heat-treat machining would just round the corners under quench distortion.
