■ Product Advantages
Ultra-High Speed for Micro-Scale Precision Machining
Typically reaches 24,000 RPM or higher, making it suitable for extremely fine engraving and drilling with small-diameter tools.
Small Size and Light Weight, Enhancing Equipment Dynamics
Its compact size makes it easy to integrate into light CNC equipment with a compact structure and fast travel speed, which helps improve the equipment's acceleration.
Extremely Low Cost, High Cost-Effectiveness
Both the purchase cost and running energy consumption are very low, making it suitable for educational purposes, hobbies, or small-scale fine operations, and is energy-efficient and environmentally friendly.
Air-Cooled Convenience, Low Maintenance Cost
Uses fan cooling, eliminating the need for any external cooling system (like water pumps or tanks), making installation and maintenance extremely simple.
Low Vibration, Conducive to Improved Surface Quality
Due to its lower power and mass, a well-designed 0.8kW spindle has relatively low vibration and noise, which helps improve the surface finish of the processed parts.
■ Application Scenarios
PCB Circuit Board Processing
Used for high-speed drilling, milling, and singulation of circuit boards, requiring extremely high speed and precision.
Micro-Engraving and Fine Lettering
Used for extremely fine engraving and marking of stamps, nameplates, small models, and craft items.
■ Adapted Equipment
● Desktop CNC Engraving Machines
Lightweight CNC platforms, typically used for fine engraving and drilling. The overall machine structure must be light to match the spindle's low torque.
● PCB Engraving/Milling Machines
High-speed drilling and milling equipment specifically for circuit board processing. Must be paired with a high-frequency inverter to drive the spindle to high RPM.
■ 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.
