Other things to consider:
If you've got the 6000 rpm spindle, there's only 2 HP (momentary) and 1.2 HP continuous at 600rpm. Also the 6000 rpm version didn't have the torque needed, more important than HP in this application.
Depending upon version of machine there were a couple different spindle drives used. The last version had an inverter that provided less low end grunt and may have had a problem with parameter settings where the machine will max out at about 50%. |
