I am not really sure where this number of 6000 rpm for the lathe spindle
came from?
The RELS certainly has limits of operation and I am not sure what they are.
As far as threading is concerned the limits are suggested as a maximum
rpm against each pitch value.
For interest some of the max threading speeds are quoted below
?? Pitch ? ? ?? Max Speed
"0.25mm" " 999rpm"
"0.70mm" " 810rpm"
"1.75mm" " 320rpm"
"4.00mm" " 140rpm"
"80tpi " ? ? " 999rpm"
"48tpi " ? ? " 999rpm"
"20tpi " ? ? " 440rpm"
" 6tpi "????? " 140rpm"
I cannot guarantee these speeds as they would be based upon the original
lead-screw pitch but they should give an idea of what is possible.
For feeds I am not sure what the maximum speeds are and I am not
competent enough to determine the values from the software or timing the
interrupt.
I can say however that if you want to run your spindle and feed at
6000rpm then the RELS is not for you. What maximum speed you can feed at
say .1mm per rev I am not sure.
With lower cost come limitations.
