CNC Spindle Motor 1.5 kW, 24000 RPM, 220V Water Cooled Precision Spindle

The 1.8 kW Water-Cooled CNC Spindle Motor is engineered for medium-duty industrial applications where balancing rotational strength and ultra-high precision is essential. Delivering a consistent 0.56 N.m of torque at a peak speed of 24,000 RPM, this motor is a preferred choice for specialized CNC bangle making machines, high-speed PCB drilling, and detailed wood carving. The integrated water-cooling jacket ensures optimal thermal management during long operating hours, protecting the precision-matched P4 grade bearings (4 x 7002 P4 arrangement) from heat-induced runout. With a compact 4.5 kg architecture and an ER11 collet system supporting tool shanks up to 7mm, this 220V spindle provides the mechanical rigidity and rotational accuracy necessary for professional-grade machining environments.

Technical FAQ

Is this spindle suitable for a bangle making machine?

Yes, the 24,000 RPM speed and high-precision 4-bearing setup make it an excellent choice for the intricate detailing required in jewelry and bangle making.

Why is water cooling better for long wood carving tasks?

Water cooling provides superior and more consistent heat dissipation compared to air cooling. This allows the spindle to maintain a stable operating temperature during long, continuous duty cycles, which is critical for maintaining precision in large wood carving projects.

What tools can I use with the ER11 nose?

The ER11 collet system is very versatile, supporting tool shanks from 0.5mm up to 7.0mm. This makes it perfect for micro-bits used in PCB drilling and finer detailing burrs.
