I see a 2d of the rotor. How thick is it? The rotor on a vane pump is usually pretty long. How accurate do you need/want to be? 1: My first thought is wire edm. 2: Or Gene's idea. A wheel/disc cutter is basically a fly cutter with more than one tooth and if it is not spinning concentric then the finish is a one tooth finish. 3: Or broach with your mill. Lock the spindle and drag the tool through the slot. Then think about broaching a circular or spiral slot by releasing the spindle. Connecting a bar on the side of the cutter/adapter. Anchor the bar at the radius you must cut and allow the bar to maintain the cutter perpendicular to the cut by using a rotating anchor. The radius of the anchor and the radius of the machine motion must match. To cut a spiral you can use a sliding/rotating anchor to allow the machine motion to determine the radius of the resulting cut.
