explain all the axis on vertical CNC router

The type of vertical 5 axis CNC router installs two rotating shafts on the main shaft and the worktable respectively. There is a rotary head at the front end of the main shaft, which rotates around the X axis. We define it as the A axis. The working range of the A axis is in Above ±90 degrees. A rotation axis is installed on the worktable to rotate around the Z axis. We define it as the C axis. The working range of the C axis is 360 degrees.

The advantage of this type of rotation axis setting method is that the workbench and the spindle are equipped for linkage processing. It is flexible and can process box-shaped workpieces with complex curved surfaces.
