This high-performance 7500-rpm spindle for 50-taper machines is driven by a 60 hp vector drive system that provides higher power throughout the rpm range than the standard spindle. It uses a Haas-built two-speed gearbox to provide a wide constant horsepower band, good low-speed torque for heavy cuts, and higher torque throughout the range above 500 rpm. Haas gears are CNC machined and hobbed out of alloy steel, heat treated to 60 Rc, and then precision ground to AGMA Class 13 quality.
The following charts are for reference only.
These power numbers are based on 240V service, supplied at the required amperage.
Actual results may vary depending on the supplied power and the operating conditions.
Haas spindles will provide these peak power numbers, which equate to 200% spindle load, for three minutes,
150% spindle load (75% of the peak number) for 15 minutes, 100% spindle load (50% of the peak number) continuously.
Note: The optional high-performance spindles have a higher power requirement than the standard spindle. Contact your local HFO for information.
