What is the primary benefit of a Dual-Head spindle?

A dual-head spindle allows you to mount two different tools simultaneously (one on each end). This is extremely beneficial for processes that require two distinct operations—like roughing and finishing—without needing a full tool changer or stopping the machine to switch bits manually.

Does the 18,000 RPM apply to both heads?

Yes, both heads are driven by the same internal motor, meaning they rotate at the same speed (up to 18,000 RPM) and frequency (300 Hz) simultaneously.

Is the cooling sufficient for both heads?

Absolutely. This model features a specialized 'Dual Air Cooling' system specifically designed to push high-velocity air across the entire motor housing, ensuring that both bearing sets and the central windings remain within safe operating temperatures during continuous use.
