[0002] Vertical four-axis machining center is a kind of numerical control machine tool commonly used in metal processing, precision manufacturing and complex parts processing. Unlike traditional three-axis machining center, vertical four-axis machining center adds a rotating axis, usually called A-axis or B-axis, on the basis of the original X-axis (horizontal), Y-axis (horizontal) and Z-axis (vertical), so that the machine tool can perform machining operations in four directions.
