Is it possible to use something like a rotary broach with a CNC Mill to make an internal hex?
Here is some of the background info. Normally I just make a hole and take the parts to another company to have them pull broached, but is it possible for me to use something like a rotary broach in a cnc mill? The material is usually something comparable to a 1020 steel (Martin off the shelf gears) that I have to machine and then they get broached. The parts have between a .375 - .625 flat to flat hex that goes through about .375 thick material (thru hole not blind). I would be doing this on a VF1. Are there any other cost effective ways to do this without spending large amounts of money or sending the parts out for EDM or broaching?
