Key Features of the BT30 ATC Spindle / 4.5kW Spindle Motor ATC

  • BT30 Tool Holder Interface – Designed for rigidity and stability, the BT30 ATC spindle ensures precise tool clamping for high-speed operations.

  • 4.5kW Spindle Motor ATC – A powerful motor capable of handling tough materials with fast acceleration and excellent torque.

  • ISO20 ATC Spindle Option – Lightweight, compact, and perfect for applications needing smaller tool sizes or faster change cycles.

  • Automatic Tool Change (ATC) – Fully automated tool changes reduce idle time and improve production efficiency.

  • High-Speed & High-Precision Bearings – Guarantees minimal runout and vibration, extending tool life and improving finish quality.

  • Water or Air Cooling Options – Efficient cooling systems protect the spindle during long runs and heavy loads.

Applications

Our CNC ATC Spindle models are widely used in:

  • Woodworking CNC routers for furniture, doors, and decorative panels

  • Aluminum and plastic machining centers for signage, molds, and parts

  • Composite and carbon fiber processing where precision and speed are critical

  • Educational and prototyping systems needing versatile, fast tool changes

This makes the BT30 ATC Spindle and ISO20 ATC Spindle perfect for automated, high-volume, and multi-tool applications.
