HSK40 QTC 2.2kW Spindle – Overview & Features

The HSK40 QTC 2.2kW Spindle from 5.0 Robotics is a high-performance, single-phase-compatible spindle system designed for the Executive CNC platform. It combines high torque at low RPMs, an efficient manual quick tool change system, and seamless software integration to offer a cost-effective alternative to full automatic tool changers.

Key Features & Benefits

1. Power & Compatibility

• Built around a 2.2kW spindle frequency controller, fully integrated within the Executive CNC system.

• Runs on standard 230V, 50/60Hz single-phase power, meaning it can be plugged into a household power outlet.

• Internally converts single-phase to variable frequency, three-phase, enabling a full three-phase 220V motor for industrial-grade performance.

2. Unique Torque Curve & Performance

• Utilizes special motor windings, delivering up to 3Nm of torque at 6000 RPM, significantly outperforming typical single-phase spindles.

• Unlike standard 24,000 RPM spindles, which experience torque loss at lower speeds, this system maintains high torque across all RPM ranges.

• Ideal for:

  • High-speed milling (4–6m/min) at 24,000 RPM

  • Aggressive drilling with 6mm, 8mm, and 10mm tools at lower RPMs

  • Heavy material removal and precision work

3. Quick Tool Change (QTC) System

• Features an HSK40 Quick Tool Change (QTC) spindle snout, allowing fast manual tool swaps without air or automation.

• Compatible with ER11, ER16, ER20, and ER25 tool holders.

• Tools can be changed using a torqued Allen key, retaining tool offsets without recalibration.

• Functions like automated tool changing routines in software, where the operator is prompted to insert the required tool, and machining resumes without re-zeroing.

• Supports pre-set tool offsets, allowing multiple tools to be prepared in advance for efficient workflow.

4. Quiet & Efficient Cooling System

• Equipped with a DC-driven cooling fan, reducing noise levels compared to conventional impeller-driven fan systems.

• Features an integrated PTC thermistor sensor, providing real-time thermal monitoring and software error detection for spindle protection.

5. Advanced Thread Milling & Rigid Tapping Alternative

• Uses helical interpolation in X, Y, and Z instead of traditional rigid tapping, enabling:

  • Threaded holes without tap breakage

  • Multi-pass cutting for hard materials

  • Dynamic adjustment of thread tolerances

  • Automated and highly precise tapping within the machining environment

• Eliminates the need for external tapping heads or specialized tapping tools.

6. Optimized for Single-Phase CNC Machines

• Provides high-speed machining for small tools while retaining low-RPM torque for heavy cuts.

• Enables both aggressive material removal and fine-detail machining.

• Designed for robust machine structures, requiring a solid, high-precision CNC platform to fully utilize its capabilities.

Conclusion

The HSK40 QTC 2.2kW Spindle is a powerful, flexible, and cost-effective spindle upgrade for Executive CNC machines, delivering industrial-grade performance while remaining simple to operate. With seamless software integration, efficient tool change routines, and high torque at low RPMs, it offers the best of both high-speed milling and heavy-duty drilling—all on single-phase power.
