Floor Model Knee Mill CNC Conversion Kits

CNC retrofitting is the process of upgrading an existing manual machine with CNC components — including a digital control unit, servo motors, and ballscrews — to enable automated or semi-automatic operation. For knee mills, a conversion kit like the Clausing CNC package adds G2 Acu-Rite controls and ballscrews, transforming the machine without requiring a full replacement.

These conversion kits use the G2 Acu-Rite Mill Power Control system. It supports 2-axis (X, Y) and optional 3-axis (X, Y, Z-Quill) operation, and allows the machine to run as a manual mill with DRO, in semi-automatic mode, or in full CNC mode — offering flexibility for varied shop environments.

Yes. The Clausing CNC knee mill conversion kit is designed for multi-mode operation. Operators can use the machine as a standard manual mill with a digital readout (DRO), switch to semi-automatic operation for assisted cycles, or engage full 2- or 3-axis CNC mode, depending on the task requirements.

Converted knee mills support spindle speeds ranging from 60–4,300 RPM or 50–5,000 RPM depending on the drive configuration. Spindle motor options include 3 HP and 5 HP, with electronic inverter variable speed or manual variable speed via sheave pulley drive — suitable for a wide range of materials and cutting operations.

Table sizes range from 9 x 49 inches to 11 x 58 inches across available models. Longitudinal (X) auto travel ranges from 30 to 35.5 inches, and cross (Y) auto travel ranges from 11.5 to 16 inches, accommodating a variety of workpiece sizes common in precision machining and mold work.

Each Clausing CNC knee mill comes with a one-year warranty backed by the Clausing Service Center. Support includes access to over 80,000 stocked parts — with 95% of orders shipped within 24 hours — plus highly qualified technicians available for phone and on-site technical assistance throughout the warranty period and beyond.
