What is the 4-axis linkage?

Four-axis linkage refers to the addition of a rotating axis based on three-axis engraving, to realize the processing of curved surfaces, such as cylinders and arcs. The four-axis linkage engraving machine can process more complicated products, it is widely used in the processing of curved surface products such as bamboo tubes. Generally speaking, the four-axis engraving machine has the following characteristics:

It can not only process the multi-axis at the same time, but also work independently on one axis. The fuselage is usually made of steel, which can run at high speed for a long time, and is reliable and durable. The 4-axis engraving machine has three different additional rotation axes, which are marked as A, B, and C. The fourth axis is usually a rotary axis, which causes an angular offset between the tool and the workpiece. The rotation angle of the fourth axis enables the engraving machine to process multiple surfaces at the same time, which improves the overall processing accuracy of the workpiece and simplifies the process.


Four-axis linkage is a processing method that adds a rotating axis based on three axes. It can complete linkage control of more than three axes and has great advantages in processing complex curved surface products. Four-axis linkage machining is an efficient and high-precision CNC machine tool that can handle various complex product processing.
