CNC Spindle Motor 6.5 kW, 24000 RPM, 380 V Water Cooled

The 6.5 kW CNC Water-Cooled Spindle Motor is a premier industrial solution engineered for maximum power and structural rigidity. Operating at 24,000 RPM with a 380V 3-phase architecture, this motor delivers an impressive 3.18 Nm of torque, making it the ideal choice for heavy material removal in stone carving, granite profiling, and deep metal engraving. The advanced water-cooling system ensures precise thermal control, maintaining operational stability during intensive 24/7 industrial production cycles. Built with a heavy-duty P4 bearing arrangement (7008 & 7005), this 23.5 kg spindle provides the mass and accuracy required to eliminate vibration even during aggressive cutting. The large ER32 collet system supports a wide range of tooling from 2mm up to 20mm, providing unparalleled versatility for large-scale CNC operations.

Technical FAQ & Operational Guide

What is the benefit of the ER32 collet on this 6.5 kW spindle?

The ER32 collet system is a significant industrial upgrade, allowing the spindle to hold much larger and more robust tools (up to 20mm shank). This is essential for heavy material removal in stone and metal where small collets like ER20 would be insufficient.

Does this motor require a high-capacity chiller?

Due to its high 6.5 kW power rating and 23.5 kg mass, we recommend using a high-efficiency water chiller or a robust circulation system to maintain thermal stability during long production runs.

Can I use this spindle for aluminum milling?

Absolutely. The high torque (3.18 Nm) and 24,000 RPM speed range make it exceptionally capable for milling aluminum and other non-ferrous metals with high precision.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
