CS Axis Function

Combined with the power turret, the CS axis enables the machine to perform milling, drilling and tapping operations in a single clamping setup.

The CS axis is equipped with a rotary encoder to deliver high positioning accuracy.

Y Axis Function

The lightweight structure of the Y-axis is directly driven by a servo motor, delivering outstanding positioning accuracy.Adopting the Y-axis helps save floor space, labor cost, machining time and fixture expenses.

CF Axis Function

Featuring high rigidity, the CF axis is an ideal choice for heavy-duty cutting applications.Paired with the power turret, the CF axis allows the machine to complete milling and tapping processes in a single clamping setup for superior precision.

Linear Guideways

High-precision, heavy-load linear guideways are mounted on the X, Y and Z axes. They maintain high positioning accuracy during rapid axis traversal and reduce wear and friction coefficient.

High-speed, high-precision ball screws are adopted

The pre-tensioned double-nut assembly eliminates backlash during movement, ensuring stable precision even under temperature variations generated during high-speed travel.
