    Machining or parts like keyway in coupling hub, how it's done

    Sometimes new coupling hubs required for new or old jobs.
    Most have keyway to be machined out after boring hub.
    Machine shop we use says they will "Hot wire" keyway, what is that ?

    It's called Hot wire EDM & find it amazing what they can do with it.
    Check out Youtube below, new to me, but been around awhile.
