3.5kW Air Cooled Spindle

This 3.5kW air cooled square spindle is designed for medium to heavy-duty CNC routing and milling. The square body provides rigidity and easy mounting, while the air-cooled system eliminates the need for pumps and coolant, simplifying installation and maintenance.

The ER20 collet system supports a wide range of tool sizes, making this spindle suitable for cutting hardwoods, plastics, composites, and aluminium. High-precision 7005DB and 6002DT spindle bearings ensure smooth rotation, accuracy, and long lifespan even under continuous machining loads.
