The Haas-designed 8100-rpm HSK-A 63 spindle provides high rigidity and high stability for high-speed, extended-reach machining applications. The HSK (Hohl Shaft Kegel, or hollow-shank taper) tooling provides dual contact between the taper and the spindle face, providing a very rigid connection that offers excellent axial and radial accuracy, especially at high spindle speeds.
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.
