Water Cooled Spindle Motor
High-precision 2.2 kW 24,000 RPM continuous-duty water-cooled spindle motor. Features 80mm outer diameter, ER20 precision collet, and whisper-quiet liquid thermal jacket for 2D/3D routing.
- check_circle 2.2 kW continuous output: Ample cutting torque for nesting 18mm MDF, hardwoods, and acrylic.
- check_circle 24,000 RPM high speed: Step-less speed control from 6,000 to 24,000 RPM via standard 400Hz VFD.
- check_circle Standard 80mm barrel: Fits universal CNC router Z-axis mounting brackets directly.
- check_circle ER20 precision collet: Clamps tool shanks up to 13mm (1/2 inch) for versatile tooling selections.
- check_circle Continuous water jacket cooling: Keeps motor running under 45°C during nonstop 10-hour shifts.
- check_circle Aviation screw-lock connector: Secure 4-pin plug with dedicated earth ground pin for safety.
- check_circle Low runout tolerance: <0.005mm radial runout minimizes cutter chatter and extends tool life.
Target Applications & Use Cases
Industrial Applications FitIntricate religious icons, artistic wood panels, and architectural accents.
Glass-smooth flame-polish-ready edges on acrylic letters and light guides.
Clean grooving and folding of aluminum composite panels for facade cladding.
High-precision modeling in high-density urethane, machinable wax, and Delrin.
Engineering & Production Benefits
Key Operational AdvantagesSignificantly quieter than air-cooled routers, ideal for shopfronts and enclosed studios.
Water cooling prevents thermal expansion of the spindle shaft during lengthy jobs.
Industry-standard dimensions make it the most cost-effective retrofit spindle available.
Precision balanced rotor protects fine 1mm and 2mm engraving bits from snapping.
Spare Part Overview & Technical Description
Precision 2.2 kW Water-Cooled Electric Spindle (80mm)
The HQD 2.2 kW water-cooled electric spindle motor is the standard benchmark for 3-axis CNC router beds (such as 1325 and 1212 formats) conducting high-speed detail engraving, acrylic fabrication, and light metal profiling. Featuring a slim 80mm outer diameter barrel machined from ground stainless steel, this spindle integrates smoothly into standard cast aluminum mounting brackets with minimal cantilever overhang.
Equipped with high-grade angular contact P4 bearings and dynamic rotor balancing, the GDZ-80-2.2KW operates up to 24,000 RPM at 400 Hz with minimal radial vibration (<0.005 mm runout). The internal water-cooling jacket ensures that heat generated by continuous cutting is dissipated via a steady stream of recirculating coolant, maintaining a stable temperature at the collet nose to eliminate thermal tool drift during multi-hour 3D relief jobs. The ER20 precision collet chuck accepts standard shank sizes from 1mm up to 13mm.
Operating Parameters & Installation:
- VFD Inverter Pairing: Designed for use with standard 2.2kW single-phase to three-phase 400Hz frequency inverters.
- Cooling Connection: 8mm water tube fittings connect directly to submersible water pump or recirculating chiller.
- Bearing Architecture: Dual 7005 P4 and dual 7002 P4 bearings handle combined axial plunging and radial milling forces.
- Noise Level: Operates below 65 dB at full velocity, providing a quiet and fatigue-free working environment.
