Re: [CAD_CAM_EDM_DRO] Milling Machine Taper question

Hello Matt,
although the surroundings of tapers are different,
generally all #40 tapers have the same angle and diameters.
So you should be able to use any #40 taper when you make the
appropriate draw bar. On my mill I use 3 different #40 tapers with
different draw bars. Works well.
Have fun
