A Comprehensive Explanation of the C-axis Function in CNC Machine Tools
In modern CNC machining, the C axis, as a key rotational axis, directly determines a machine tool’s capability to machine complex parts. This article clearly defines the C axis, breaks down its core functions, and helps practitioners quickly understand its role and value. 1. What is the C Axis in CNC Machine Tools The basic coordinate axes of CNC machine tools are three linear axes: X, Y, and Z. The C axis is a rotational axis that rotates 360° around the Z axis (spindle centerline), forming a multi-axis machining system together with linear axes. The C axis is mainly implemented in two forms: rotary table type and tilting head type . Its core function is to provide precise circular rotation for the workpiece or cutting tool, breaking through the limitations of conventional linear-axis machining and enabling the machining of complex circular and curved surfaces. Unlike the A axis (rotating around the X axis) and B axis (rotating around the Y...
