Generally, when the workpiece is not positioned in space, there are six degrees of freedom, X, Y, Z three linear displacement degrees of freedom and the corresponding three A, B, C rotational displacement degrees of freedom. Generally speaking, the three-axis machining center we use is to process the objects separately through the three linear axes X, Y, and Z. The four axis is to add the A rotation axis on the basis of the three axis, that is, to process the object on the four degrees of freedom of displacement of X, Y, Z, and A.
4-axis CNC machining and four milling also produce the smooth surface finish that is essential for many manufacturing applications. Despite its utilization of advanced technology, 4-axis CNC machining provides superior results at an extremely affordable price point. This machining process is a preferred choice in the aerospace industry, which is renowned for requiring precise and accurate machining of complex parts.
