There are also two ways for the rotary axis of the horizontal five-axis machining center. One is that the horizontal spindle swings as a rotary axis, plus a rotary axis of the worktable. Realize pentahedron processing,
Disadvantage: The rigidity of the spindle is poor, but it is not linked. It is suitable for different processing requirements of the four-axis machining center for vertical and horizontal conversion.
Advantages: simple and flexible processing, simple replacement of the spindle vertical or horizontal rotation, low manufacturing cost, very practical.
The other is the traditional rotary axis of the worktable. The A-axis of the worktable set on the bed generally has a working range of +20 degrees to -100 degrees. There is also a rotary table B-axis in the middle of the worktable, and the B-axis can rotate 360 degrees in both directions.
Disadvantages: The worktable is limited, the structure of the rotary shaft is more complicated, and the price is also expensive.
Advantages: The rotary shaft can also be equipped with circular grating feedback, and the indexing accuracy can reach a few seconds. It is often used to process complex surfaces of large impellers.
