Wire EDM - 160 mm in Carbide

Wire EDM machining beyond 100 mm

Cutting over 100 mm in a wire EDM machine is complicated, especially when aiming for high-accuracy cuts. Makino EDM machines are capable of making the longest and more precise cuts.
In this demonstrator, we used a CIS VM30 block of steel of 160 mm width.

Our process had the following parameters:
  • Wire diameter: 0.2 mm
  • Number of cuts: 9
  • Oil-based dielectric
  • Machining time: 15 hours, 42 minutes

With these parameters we achieved:
  • Straightness: 1 micron
  • Roundness: 1.7 micron
  • Surface finish: Ra 0.05 micron
