Big problem with a Super X 3 is the spindle motor, just a 1000 W 3 phase brushless motor with variable speed.
It's not a bad motor but because it's a manual machine it 's going to get used with large cutters and flycutters.
Winding to speed down reduces the revs but it doesn't increase torque.
Only a gear or belt reduction will do this.
It's the same motor and drive as in the CNC's but these get away with it by running smaller cutters at higher speed to remove the same amount of work. You never see a CNC using a boring head, they always interpolate with smaller cutters. Whilst the X3 gearbox is noisy and it has a smaller motor it is better at lower speeds.
