3.5kw air cooled CNC Spindles in Wood CNC Router

A 3.5kW air-cooled CNC spindle is an essential component in wood CNC routers, offering a versatile balance of power and performance ideal for a wide range of woodworking tasks.

Designed for precision, efficiency, and reliability, this spindle type is especially well-suited for both small and large-scale woodcutting, engraving, and carving operations. Its air-cooled system eliminates the need for water-cooling setups, making it easier to maintain while delivering consistent results. Whether working with softwoods, hardwoods, or composite materials, a 3.5kW spindle ensures high-quality outcomes, enhancing the productivity and flexibility of any woodworking shop.

Here are the main parameters for a 3.5kW air-cooled CNC spindle typically used in wood CNC routers:

Main Parameters:

Power Output: 3.5 kW
Speed Range: 0 – 24,000 RPM (variable speed)
Cooling Type: Air-cooled (fan-based cooling system)
Voltage: Typically 220V or 380V (depending on model)
Frequency: 300 Hz
Spindle Taper: ER20 (supports various tool sizes, typically up to 12mm)
Runout Accuracy: ≤ 0.01 mm (for precise cuts)
Bearing Type: Angular contact ball bearings (high precision and durability)
Weight: ~10 – 12 kg
Mounting Diameter: 80 mm (common size for most CNC routers)
Lubrication: Grease (maintenance-free)
Noise Level: Lower compared to water-cooled spindles

These parameters make the 3.5kW air-cooled spindle an excellent choice for woodworking applications requiring precision and reliability.
