Smoke on the water? Technically, it’s smoke on the oil.
That’s a sinker EDM job running in our shop. The electrode never touches the part. It erodes the shape into the workpiece while submerged in dielectric oil, which insulates the gap, carries away debris, and keeps the work cool.
It’s how we produce deep cavities, thin ribs, sharp internal corners, and blind features in hardened material: geometry a cutting tool can’t reach.
