Technical FAQ & Operational Guide
What is the benefit of the BT30 interface on a 5.5kW spindle?
The BT30 interface is a globally recognized industrial standard that provides excellent clamping rigidity and rotational accuracy. It is significantly more robust than collet-based systems, allowing for higher material removal rates and the use of a wider variety of industrial milling and drilling tools.
Is this spindle compatible with any ATC system?
Yes, this motor is designed with the mechanical architecture required for Automatic Tool Change (ATC) systems. It features the necessary drawbar mechanism to interact with tool carousels or linear changers typically found in high-end VMCs.
Why is water cooling recommended for this 5.5kW model?
At 18,000 RPM, high-power spindles generate considerable heat from both friction and electrical frequency. Water cooling provides the most efficient and consistent thermal regulation, ensuring that the P4-grade bearings and motor windings stay within safe operating temperatures during long production cycles.
