Water Cooled CNC Spindle
Compact 65mm / 80mm barrel 1.2 kW 24,000 RPM high-speed engraving spindle with ER11 collet. Specially tuned for fine 3D relief carving, acrylic signage, and PCB isolation.
- check_circle Compact 65mm barrel: Drastically reduces Z-axis moving mass for faster 3D plunge moves.
- check_circle 24,000 RPM high velocity: Delivers high surface cutting speeds required by tiny micro-diameter tools.
- check_circle ER11 precision collet: Clamps micro bits, PCB endmills, and engraving cutters from 1mm to 7mm shank.
- check_circle Minimal runout (<0.003mm): Safeguards fragile carbide engraving tips from eccentric vibration snapping.
- check_circle Internal water circulation: Prevents thermal expansion and maintains sub-millimeter carving depth consistency.
- check_circle Low electrical draw: 1.2 kW power rating keeps energy consumption exceptionally low during long shifts.
- check_circle All-metal chrome housing: Corrosion-resistant alloy steel body built for long industrial durability.

Spare Part Overview & Technical Description
High-Speed 1.2 kW Water-Cooled Engraving Spindle
The HQD 1.2 kW water-cooled CNC spindle (Model GDZ-65) is engineered specifically for fine-detail engraving, high-speed micromachining, and lightweight multi-head router configurations. Boasting a compact 65mm (or 80mm) barrel profile and lightweight cylindrical geometry, this spindle reduces moving mass on the Z-axis gantry, enabling blistering acceleration and intricate micro-step positioning during high-resolution 3D relief carving.
Operating up to 24,000 RPM driven by a 400Hz frequency inverter, the spindle uses high-precision ceramic ball bearings paired with dynamic balanced rotors to achieve runout tolerances below 0.003mm. The water jacket maintains cool operating temperatures during lengthy engraving runs, preventing thermal spindle elongation that would otherwise compromise fine engraving depth consistency on delicate materials like acrylic, brass stamps, or circuit boards.
Operational Best Practices:
- Micro-Tooling Protection: Extremely low runout allows use of 0.1mm conical engraving bits without tip fracture.
- Water Temperature Regulation: Maintain cooling bath between 20°C and 30°C for optimal bearing lubrication viscosity.
- Multi-Spindle Gantry Mounting: Slim 65mm diameter allows tight spacing on multiple synchronous carving heads.
- High Duty Cycle: Can run continuously without overheating on delicate 12-hour relief jobs.
