Why is water cooling preferred for marble and stone carving?

Stone machining generates significant heat and abrasive dust. Water cooling provides a sealed, high-efficiency thermal management system that keeps the motor at a constant temperature even during long, high-torque operations, unlike air-cooled systems that can be affected by dust.

Can this motor be run on a single-phase supply?

No, this model is designed for an industrial 380V 3-phase supply. You will need a compatible 3-phase VFD to operate this motor correctly.

What size tools can I use with the ER20 collet?

The ER20 collet system on this 4.5 kW spindle allows you to clamp tool shanks from 1mm up to 13mm, providing range for both fine engraving and heavy material removal.
