Abrasive Machining | Thread grinding
Even a little thread gage like Starret or brown and Sharpe sells is probably adequate for 60 degree threads. Stick it in the thread and look at it with magnification. But for high precision threads, an optical comparator is the way to fly. As you change the diameter of the parts you grind, you have to change the helix angle of the wheel.
