■ Product Advantages
Stronger Tool Clamping Capability (ER25)
The ER25 collet, compared to the ER20 (which usually clamps up to 13mm), can clamp larger diameter tools (typically up to 16mm). This enables the spindle to handle larger feed rate roughing tools or scenarios requiring large diameter cutters for slotting and nesting.
Robust Cutting Torque (3.5kW)
The 3.5kW power segment provides ample torque to support deeper cuts and greater feed rates, ensuring high material removal rates for medium-hardness materials.
High Rigidity from Square Structure
The square casing design guarantees extremely high stability during spindle mounting. When performing medium-to-heavy cutting, it effectively suppresses spindle vibration and radial runout, thus improving final machining precision and tool life.
Air-Cooled Convenience, Low Maintenance Cost
It uses an integrated fan for cooling, eliminating the need for complex external water circulation systems. Installation is quick and simple, avoiding common maintenance hassles of water systems like leaks or freezing.
Excellent Speed Characteristics
Typically features high-speed capability ranging from 18,000 to 24,000 RPM, allowing it to meet both the torque demands of roughing and the surface finish requirements of fine machining.
■ Application Scenarios
Wood Nesting and Heavy Routing
An ideal choice for high-volume nesting on production lines for panel furniture and custom homes. The ER25's ability to clamp large diameter nesting cutters significantly boosts cutting efficiency.
Complex Shape Roughing
Suitable for high-material-removal, deep-layer routing and roughing of solid wood, artificial wood, and thick MDF, laying the foundation for subsequent finishing.
Fast Cutting of Thick Non-Metallic Materials
Rapid, deep cutting of thick acrylic, high-density PVC boards, epoxy resin, etc., especially for large-thickness panels requiring one-pass cutting.
Light Metal Processing (Medium Intensity)
Can be used for larger diameter tool milling and trimming of soft metals like aluminum sheets and aluminum profiles, with the rigidity supporting the increased cutting forces.
■ Adapted Equipment
● High-Performance CNC Nesting Machines
Specialized automatic loading/unloading, cutting, and drilling machines for the panel furniture industry, where the large clamping capacity is crucial for nesting efficiency.
● Medium-to-Large Wood Engraving Machines
Suitable for large-format, complex, deep-level wood carving and contour routing.
● High-Performance Advertising Engraving/Milling Machines
Equipment dedicated to large-format, high-feed-rate cutting of thick advertising panels.
● Light Machining Centers
Used for high-efficiency milling and drilling of general materials (including light metals like aluminum and copper), particularly when large-diameter drills or end mills are required.
■ 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.
