Working range of AC rotating axis of CNC five axis machining center

Generally speaking, the axis around the x-axis of the five axis CNC machining center is defined as the a-axis. The working boundary of the a-axis is + 30 ° to – 120 °. The worktable of the five axis machining center is equipped with a rotating shaft. This rotating shaft ring rotates around the z-axis. We define it as the c-axis. The working boundary of the c-axis is 360 degree rotation. For the five axis machining center with a rotating shaft and C rotating shaft, the workpiece can be clamped once to finish machining other than the mounting surface. Generally, the small graduation value of a-axis and c-axis is 0.001 degrees. In this way, it is better to remove the other surfaces of the installation surface without angle, and to process the skew surface, skew hole and other complex processes. It can be realized that if the a-axis, c-axis and XYZ linear three-axis are processed in five-axis linkage, the complex curved surface workpiece can be processed. Of course, good CNC system, servo motor system and software support are needed.

Structural advantages of AC rotating shaft configuration in five axis machining center

The advantages of the above AC rotating shaft configuration are simple structure, good rigidity of the main shaft, low manufacturing cost and so on. Generally, the worktable can not be configured too large, and the load-bearing is also relatively small. The unique reason is that when the rotation axis of a turns to 90 degrees or more, when the workpiece is processed, it will bring a lot of load-bearing moment to the worktable.
