I use HSMAdvisor for most of my feeds and speeds, and it has an approximate power curve built in for the high range. Does anyone have an official power curve with peak HP and peak torque values?
This would be super helpful as for now it’s a lot of guesswork in order to find the right balance between pushing the machine and keeping the spindle from bogging down.
Are the power curves available for the “low belt” (Low speed configuration)?
Not at this time, unfortunately.
Sam,
This is great do you happen to have these charts for the 770MX?
Outstanding Printing this for my folder.
Do you have these for the PCNC1100 ( I have a Series 3)?
A lot of owners wold be grateful I think…
I don’t think PCNC machines ever had a torque curve as the dyno was only available many years after developing the PCNC’s , but I’ll ask the engineering team.
If you have curves for a PCNC770 that would be great!
@Ken_Strauss and @Peter_Neill Got word back from Engineering and other than initial calibrations on the dyno during it’s testing the PCNC’s were never tested, unfortunately.
Does anyone have the 1100m power curves?
The 770 low belt power curve doesn’t seem to add up. If the machine is delivering 1.25HP at the spindle at 1,000 RPM, then the formula for torque is 1.25HP * 5252 / 1000RPM = 6.565 ft-lb.
