💡 What is the practical difference between water-cooled CNC spindles and air-cooled spindles for wood and plastic engraving?

This handy comparison helps you weigh cooling methods for long jobs and precision.

• Water cooling keeps temperature stable under load, reducing thermal drift
• Better high-speed stability up to 24000 RPM for cleaner finishes
• Requires a coolant system, but extends tool life and reduces warping
• ER20 collet compatibility broadens tooling options for non-metal materials
