What is Wire EDM of thin shutter blades and aperture disks?
Wire EDM of thin shutter blades and aperture disks capability for titanium components
Wire and sinker EDM capability for Wire EDM of thin shutter blades and aperture disks, achieving burr-free results with multi-pass finishing strategy and submerged machining.
Engineering Parameters & Capabilities
Wire EDM uses a continuously traveling brass or coated wire electrode under precision CNC control to erode titanium along a programmed path. Submerged in deionized water dielectric, the process cuts intricate profiles and sharp internal corners that are impossible with conventional methods, specifically for thin walls. Thin walls for aerospace present unique challenges: wall thickness < 1 mm is prone to chatter and deflection. Negative tool rake and reduced radial engagement (5%) are required. Vacuum fixturing or wax/pitch potting is used for stability.
| Parameter | Primary Method | Alternative Method |
|---|---|---|
| Min Internal Corner R | 0.015 mm (wire radius) | 0.5 mm (milling) |
| Taper Angle | +30° (5-axis wire EDM) | 0° (straight cut) |
| Re-cast Layer | 1–5 µm; removable by etching | No re-cast layer |
