Compact Power for Precision Machining: 2.2kW ATC Spindle for CNC Routers

In the CNC world, not every application needs a massive spindle.

For light-duty yet highly precise operations like engraving, panel cutting, and small-scale woodworking, the 2.2 kW ATC spindle offers the perfect balance of power, speed, and automation.

Compact in size but strong in capability, the 2.2 kW spindle ATC is ideal for CNC routers that require reliable automatic tool changing and high-speed precision, without the energy demands or bulk of larger motors.

What Is a 2.2kW ATC Spindle?

A 2.2kW spindle ATC is a compact automatic tool change spindle motor designed for CNC routers and engraving machines. It features an ATC (Automatic Tool Changer) interface—usually ISO20 or BT20—that allows your machine to switch tools automatically, improving efficiency and reducing manual downtime.

This spindle is well-suited for:

  • Woodworking

  • Sign-making

  • Acrylic and PVC cutting

  • Soft metal and aluminum milling

  • PCB or mold prototyping

2.2kW ATC Spindle | Compact CNC Router Spindle with Tool Change

Key Features of a 2.2kW Spindle ATC

  • Automatic Tool Change (ATC): Switch between cutting tools without stopping your machine.
  • High Speed: Reaches up to 24,000 RPM for clean, smooth cutting of wood, plastic, and soft metals.
  • Energy-Efficient: Lower power consumption compared to large spindles while still delivering professional-grade performance.
  • Air-Cooled or Water-Cooled Options: Choose based on your processing intensity and workshop setup.
  • Lightweight & Compact: Ideal for small-format CNC routers or desktop ATC engraving machines.
