Re: Mill tool changer without auto drawbar?
I have an older Bridgeport Boss 5 mill with an Erikson Quick Change 30 Spindle on it. This set up does not use a drawbar, the tool holder is pushed into the taper from a special "nut" on the bottom of the spindle. The nut is tightened to push the holder in and when it come time to remove the tool it is lossend a 1/4 turn to break the tool free from the taper. One could make a tool changer that works in this fashion I suppose.
