Product Features

Air-Cooled Structure

The air cooling design removes the need for a water pump, tank, or cooling pipes, making installation easier for CNC routers and woodworking machines.

Low Maintenance

Without a water circulation system, the spindle reduces risks related to leakage, water quality, pump failure, and pipe blockage.

Suitable for Dry Processing

HQD air cooled spindles are suitable for dry working environments, especially woodworking carving, cutting, and routing applications.

18000rpm High-Speed Performance

With a speed of 18000rpm, the spindle supports efficient cutting, engraving, and routing. For woodworking, 12000–18000rpm is recommended based on material and tool conditions.

Multiple Power and Collet Options

Power options include 1.5KW, 2.2KW, 3.5KW, 6KW, and 7.5KW, with ER20, ER25, and ER32 collet options for different CNC router requirements.

Easy Replacement and Upgrade

The spindle can be used for new machine installation, replacement, or equipment upgrades based on voltage, power, collet type, mounting size, and application needs.

Product Application

Air-cooled spindles are widely used in mechanical processing, woodworking machinery, CNC engraving, cutting, and other material processing equipment where stable high-speed rotation and reliable heat dissipation are required. By adopting air cooling technology through a built-in fan or external airflow, the spindle helps dissipate heat generated during operation, reducing the risk of performance decline caused by overheating.

Thanks to their simple structure, low maintenance requirements, and strong adaptability, HQD air cooled spindles are well suited for woodworking carving machines, cutting machines, and dry or low-waterproof processing environments. They can be used with 3–12mm milling cutters or saw blades, making them a practical solution for density board, solid wood, and similar woodworking applications.
