Industrial Water Cooled Spindle For CNC Steel Wood Project
✔️ 3.7kW ER20 Collet Single Unit Sealed Ceramics 6k-24k RPM Liquid Cool

This 3.7 kilowatt router motor handles heavy cutting loads for steel, hardwood, and aluminum parts. It bolts right into CNC routing benches, plasma cutters, or engraving frames where smooth turns and steady torque keep jobs running tight.

✅ Output sits at 3.7 kW for 220V or 380V supply lines
✅ Angular contact ceramics spin steady up to 24000 rpm
✅ ER20 chuck locks collets from 1mm to 13mm grip size
✅ Hollow core liquid loop dumps heat fast to stop thermal shift

💡 How does liquid cooling give your CNC router an edge on steel?

Sweat goes out fast and lets your cutter bite tough material without burning up.

Tap water runs clean through the inner sleeve to kill heat lag on thick metal sheets.

Internal sealed balls push less drag than standard greased hubs.

Adjust your frequency setup for a handy grind that locks steady torque.
