■ 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.
