■ Product Advantages
Outstanding Sustained Heavy Cutting Capability (6.0kW)
Belonging to the large power segment, it provides extremely high sustained torque, effortlessly driving large-diameter tools for high-speed, large-volume heavy cutting. This is crucial for achieving industrialized high efficiency and high output.
Superiority of the ER32 Collet
The ER32 collet (typically max clamping 20mm) can securely grip various large-diameter roughing tools. This gives the spindle a high-efficiency advantage in roughing and nesting stages that require fast material removal.
Ultimate Rigidity from Flying Edge Structure
The short nose (flying edge) design brings the tool clamping point infinitely close to the spindle bearings, which significantly enhances the bending rigidity at the spindle end. In high-feed, high-load heavy cutting tasks, this minimizes vibration and tool runout, ensuring ultra-high machining precision.
Deeply Optimized for Automatic Tool Changer (ATC) Systems
This spindle structure is the perfect partner for ATC systems, enabling fast and reliable automatic 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 all maintenance requirements of external water circulation systems, offering extremely high reliability. It is particularly suited for operation in industrial environments demanding 24/7 continuous running and where water line maintenance is inconvenient.
■ Application Scenarios
High-End Panel Furniture/Cabinet Automated Production Lines
Applicable to CNC nesting machines and machining centers equipped with ATC systems, performing ultra-high-efficiency, continuous operations such as panel cutting, slotting, and drilling, especially suitable for nesting with large-diameter tools.
Heavy-Duty Solid Wood and High-Density Material Processing
Performing deep-layer, high-intensity, large-volume routing, relief carving, and complex 3D shaping on thick solid wood, high-hardness artificial wood, and heavy high-density panels.
Large Mold and Prototype Manufacturing
Used for large-volume roughing of large resin, artificial wood, and high-density foam molds, where the demand for material removal rate is extremely high.
High-Speed Heavy Cutting of Light Metal Materials
Can be used for milling and drilling of soft metals like aluminum alloys and copper, where the 6kW power and ER32 clamping force are crucial in metal processing.
■ Adapted Equipment
● Flagship Automatic Tool Change (ATC) Machining Centers
Flagship CNC machines in the woodworking or advertising industry equipped with tool magazines, requiring high-efficiency, multi-process complex automated production.
● Heavy-Duty CNC Nesting Centers
Used as the main cutting unit for continuous, high-intensity, heavy-load production in the panel furniture industry.
● Large Gantry High-Rigidity Engraving/Milling Machines
Used for roughing and semi-finishing of large-format, high-precision, heavy-duty materials.
● Automated Integration Workstations
Used as the power unit on automated assembly lines for continuous, 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.
