Well, I bit the bullet and ordered the IH Mill manual version. Still waiting on it to arrive. I will be converting it to cnc but woul like to see what ideas ya'll would have about an ATC for the NT 30 taper. I will be using a VFD on the motor and will want to use the tangs on the NT 30 spindle. Question is how accurately can I stop the spindle if I used an index pulse from the spindle. In order to switch tools I need to stop the spindle exactly the same each time. This will allow the spindle tangs to line up every time otherwise I will have problems.
Any thoughts on this.
EDIT:
I will be using MACH software with a smoothstepper and Gecko drives for the servo motors on the axis. Spindle will be 2 or 3 HP Hatachi with AC motor.
