After the fourth axis is added to the NC machining center machine tool, it is usually called a four axis NC machining center. It can complete tasks that the three-axis machine tool cannot complete at one time. It realizes the multi-faceted processing of the processed products through the rotation of the fourth axis or the fourth axis bridge plate, which not only overcomes the processing that the three-axis machine tool cannot complete, but also greatly improves the processing efficiency of the machine tool and reduces the number of clamping times. It increases the benefit of the enterprise.

The fourth axis of the machining center refers to the CNC indexing head of the machining center. We usually call the fourth axis the CNC indexing head. The CNC indexing head is widely used and has many brands. It has a good market effect, and can improve the efficiency of enterprises and processing efficiency. At present, many parts can not be processed without a four axis machining center.

Advantages of assembling the fourth axis in CNC machining center:

It can improve the machining plane of the tool, reduce the repeated clamping of the workpiece, greatly improve the overall machining accuracy of the workpiece, simplify the process, improve the production efficiency, and shorten the production cycle. Therefore, four axis machining center is widely used. By adding a rotating shaft, the angle offset between the tool and the workpiece can be generated, the machining range can be expanded, and favorable cutting conditions can be formed.
