AI Technical Summary

Technical Problem

Existing machine tools face limitations in achieving high-speed machining due to costly high-speed spindles that can only absorb limited forces, and existing fluid-driven spindles have speed dependent on load, leading to high operating costs.

Method used

A tool holder with an integrated electric drive, energy storage, and control unit that allows for high-speed rotation of tools without external power connections, enabling easy installation and cost-effective high-speed machining.

Benefits of technology

The tool holder achieves high-speed machining up to 200,000 rpm, reducing tool changes and operational costs, while allowing 'plug-and-play' installation and efficient energy management.
