Hi Group
I am working on a spindle design for metal machining.
I was wondering what the high and low spindle rpms
would be required for general machining. I`ve seen the
Bridgeport specs at 0 to 4500 rpms. The high end at
4500 seems high for metal when is this higher speed
required. I will be using a PMDC motor to drive the spindle.
I need to know if I need to gear up or down for
maxium usage. The PMDC motors are avalable in 1725
or 2500 rpms.
Thanks
