■ Product Advantages
Ultra-Strong Sustained Heavy Cutting Capability (7.5kW)
Provides extremely high sustained torque and power reserve. It effortlessly drives large-diameter tools for high-speed, large-volume cutting, ensuring maximum industrial efficiency and material removal rate.
Significant Low-Noise Characteristics
The effective reduction of wind and mechanical noise generated during high-speed rotation is achieved through the integration of a separate low-noise fan at the tail end, enhancing the working conditions for machine operators.
Ultimate Rigidity from Flying Edge Structure
The short nose (flying edge) design brings the tool clamping point infinitely close to the spindle bearings, providing top-tier anti-bending rigidity. In high-feed, heavy-load cutting tasks, this minimizes vibration, ensuring ultra-high machining precision.
Built for Automatic Tool Changer (ATC) Systems
This spindle structure is the standard configuration for high-end ATC systems, enabling millisecond-level fast tool changes, greatly increasing the efficiency and flexibility of multi-process automated production.
Maintenance-Free and Reliability of the Air-Cooled System
Uses an integrated fan for forced cooling, completely eliminating the maintenance needs of external water circulation systems, offering extremely high reliability, and guaranteeing stability for industrial 24/7 continuous operation.
■ Application Scenarios
High-End Panel Furniture/Cabinet Machining Centers
Applicable to large custom home factories, especially in automated production workshops that are semi-enclosed or have requirements for ambient noise, performing ultra-high-efficiency panel cutting, slotting, and drilling.
Heavy Mold and Prototype Manufacturing Roughing
Used for large-volume, high-strength roughing of large molds, ensuring efficiency while maintaining an operator-friendly workshop environment.
High-Speed Heavy Cutting of Medium-Intensity Metals
Can serve as the core of high-performance light metal machining centers, used for power milling of soft metals like aluminum alloys and copper.
■ Adapted Equipment
● Ultra-Heavy-Duty CNC Nesting Centers (Silent Type)
Automated nesting equipment used for continuous, high-intensity, heavy-load production, which also requires reducing overall equipment operating noise.
● Large Gantry High-Rigidity Engraving/Milling Machines
Used for roughing and semi-finishing of large-format, heavy-duty materials, where operator comfort is emphasized.
● High-Precision Automated Integration Workstations
Used as the power unit on automated assembly lines for continuous, super-heavy-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.
