That is an interesting point. I am getting ready to add gear tooth sensors on the bull gear so I can rigid tap. I don't have a braking resistor on my drive. Currently the mechanical spindle brake engages when the spindle stops via a pneumatic cylinder. To be honest I am not sure if it would engage during a spindle reversal as I don't do that currently. It probably would not. Does the rigid tapping cycle stop the spindle or does it do a reversal without stopping? M3 M5 M4 M5 or M3 M4 M5? I figured that the drag from tapping would stop the spindle pretty quickly without the resistor. I would like to hear more about your experience with this situation.
