There is also a rotary table in the middle of the worktable of the 5 Axis CNC router manching center, which revolves around the Z axis at the position shown in the figure, which is defined as the C axis, and the C axis rotates 360 degrees. In this way, through the combination of A-axis and C-axis, except for the bottom surface of the workpiece fixed on the worktable, the other five surfaces can be processed by the vertical spindle. The minimum graduation value of A-axis and C-axis is generally 0.001 degrees, so that the workpiece can be subdivided into any angle, and inclined surfaces, inclined holes, etc. can be processed. If the A-axis and C-axis are linked with the XYZ three linear axes, complex spatial surfaces can be processed. https://www.pumacnc.com/5-axis-c...ter-manching-center.html
