Technical FAQ & Operational Guide
What kind of frequency drive (VFD) is required for 40,000 RPM?
This spindle operates at an ultra-high frequency of 1333 Hz. You must use a specialized high-frequency Variable Frequency Drive (VFD) that supports output frequencies above 1333 Hz. Standard industrial VFDs are typically capped at 400-600 Hz and will not work.
Why is ISO20 preferred for 40,000 RPM?
ISO20 is a precision-tapered interface designed for high-velocity stability. Its smaller, balanced mass compared to BT30 ensures minimal vibration and runout at 40,000 RPM, which is critical for maintaining surface finishes in micro-milling.
Does this ATC spindle require compressed air?
Yes, Automatic Tool Change (ATC) spindles require clean, dry compressed air to operate the internal pneumatic drawbar that releases and grabs the tool holders, and often for spindle taper air-blow to keep the interface clean.
