FAQ
How to choose the right power?
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.What should be noted when using an air-cooled spindle?
Keep it clean, don't overload it, and check if the fan is spinning correctly.
How to match an air-cooled spindle with an inverter?
The inverter's power, voltage, and frequency must match the spindle's specifications.
Is it normal for an air-cooled spindle to get hot during use?
Slight warmth is normal. However, if it feels very hot to the touch, the fan may be broken or the spindle could be overloaded.
What is the typical lifespan of an air-cooled spindle?
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.
