■ Product Advantages
Powerful Sustained Cutting Torque (4.5kW)
The power is in the high-power range, providing significantly more torque than 3.5kW. It easily handles deep cutting and high-speed nesting of high-hardness panels and thick solid wood, significantly boosting material removal rates in industrialized production.
Ultimate Rigidity from Flying Edge Structure
The short nose (flying edge) design pulls the tool clamping point extremely close to the spindle bearings, greatly enhancing the bending and anti-vibration rigidity at the spindle end. This is vital in high-feed, high-load heavy cutting, effectively guaranteeing precision and extending tool life.
Reliability and Convenience of the Air-Cooled System
Uses an integrated fan for cooling, completely eliminating the maintenance needs of external water circulation systems. It offers high reliability and low maintenance cost, making it particularly suitable for operating in dusty industrial environments that require 24/7 continuous operation.
Industrial-Grade Durable Design
Engineered specifically for long-term, high-load industrial continuous operation, featuring excellent heat dissipation performance and robust bearing configuration to ensure stable performance under heavy loads.
■ Application Scenarios
Industrial-Grade Automated Panel Furniture Processing
Applicable to CNC nesting machines and machining centers equipped with ATC systems, performing high-efficiency, deep-level continuous operations like panel cutting, slotting, and drilling.
Heavy-Duty Woodworking and Mold Roughing
Performing large-volume, deep cutting routing and relief carving on solid wood, thick artificial wood, and high-density board (MDF), guaranteeing efficiency in the roughing stage.
Fast Processing of Thick Non-Metallic Materials
Suitable for fast, deep cutting and shaping of thick acrylic, high-density PVC, epoxy resin, and other materials.
High-Speed Milling of Light Metal Materials
Can be used for milling and drilling of soft metals like aluminum alloys and copper sheets; its high rigidity and power ensure both precision and efficiency in processing.
■ Adapted Equipment
● Medium-to-Large CNC Nesting Centers
Used as the main cutting unit for continuous, high-intensity production in the panel furniture industry.
● Automated Integration Workstations
Used as the power unit on automated assembly lines for continuous, high-load, multi-functional processing of products.
■ FAQ
Q: How to choose the right power?A: It depends on the material you're processing.
2.2kW: Suitable for engraving materials like acrylic and PVC.
3kW - 4.5kW: Most common, used for nesting and engraving various wood panels.
6kW and above: Ideal for heavy cutting, like cutting solid wood.
Q: What should be noted when using an air-cooled spindle?A: Keep it clean, don't overload it, and check if the fan is spinning correctly.
Q: How to match an air-cooled spindle with an inverter?A: The inverter's power, voltage, and frequency must match the spindle's specifications.
Q: Is it normal for an air-cooled spindle to get hot during use?A: Slight warmth is normal. However, if it feels very hot to the touch, the fan may be broken or the spindle could be overloaded.
Q: What is the typical lifespan of an air-cooled spindle?A: The lifespan of an air-cooled spindle mainly depends on its bearings. With proper maintenance and without overloading, a good spindle can last for thousands or even tens of thousands of hours.
