■ 2.2kW Air Cooled Spindle Motor Advantages

High Cost-Effectiveness, Low Purchase Cost
Ideal for small studios, advertising production shops, and educational purposes.

Flexible Application, Wide Versatility
The moderate 2.2kW power is capable of handling the engraving, hollowing, and light cutting of most non-metallic materials.

Simple Installation
Uses fan cooling, eliminating the need for an external water circulation system; quick to install and requires minimal maintenance.

High Machining Precision
The speed performance typically reaches a high rotation of 24,000 RPM, ensuring a smooth cutting surface when engraving materials like acrylic.
■ Application Scenarios

Advertising Engraving
Fine engraving, cutting, and grooving of acrylic, PVC, double-color board, and foam board.

Light Woodworking
Engraving and relief work on wooden crafts, small furniture components, and wooden signage.
■ Adapted Equipment
● Small-Scale Advertising Engravers
Used for engraving advertising materials such as acrylic, PVC, double-color board, and foam. These machines typically feature 3-axis or 4-axis linkage and have smaller working table sizes.
● Woodworking Craft Engravers
Used for producing wooden relief carvings, small furniture accessories, wooden sign lettering, and other refined woodworking products.
● General CNC Machines
Applicable to general CNC platforms requiring moderate power and high speed for light milling and drilling operations.
■ 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.
