Knee Mill CNC Retrofit Kits

Yes. Clausing CNC knee mills equipped with the G2 Acu-Rite control can be operated as manual machines with a DRO, in semi-automatic mode, or as full 2 or 3-axis CNC machines. This flexibility allows operators to switch between modes depending on job requirements without reconfiguring the machine.

The retrofit kit uses the G2 Acu-Rite Mill Power Control, a proven CNC system designed specifically for knee mills. It supports X, Y, and optional Z-axis ballscrew integration, programmed feed rates up to 100 in/min, and rapid feed rates of 100 in/min for efficient, accurate machining operations.

Depending on the model, retrofitted knee mills offer spindle speeds from 60 to 4,300 RPM with manual variable speed, or 50 to 5,000 RPM with electronic inverter variable speed. This range supports a wide variety of milling operations across different materials and tooling requirements.

The retrofit supports 2-axis CNC control (X and Y) as standard, with an optional 3rd axis (Z-quill) available on select Clausing models. Ballscrews are installed on the controlled axes to ensure precision movement, backlash elimination, and programmed feed rates up to 100 in/min.

Clausing CNC knee mill retrofit kits are backed by a one-year warranty through the Clausing Service Center. Highly qualified technicians provide phone and on-site support, and the service center maintains over 80,000 parts, with 95% of all orders shipped within 24 hours to minimize production downtime.

Knee Mill CNC Retrofit Kits are widely used in precision manufacturing, general machining, aerospace and defense, medical device manufacturing, and mold machining. They are suited for any professional machine shop or industrial facility requiring accurate, repeatable milling with the flexibility to operate manually or under full CNC control.
