[0030] This vertical and horizontal composite machining center installs the workpiece to be processed on the first rotary table 120, drives the second rotary table 231 to move the machining spindle 232 along the Z direction to position, and then rotates the second rotary table 231 to position the machining spindle 232 vertically or horizontally, so as to be applied to various machining states of vertical or horizontal and any inclination angle. It can complete the one-time machining of parts that need to be processed on multiple sides through one clamping, thereby effectively improving the machining efficiency of the parts. This equipment can save the number of machining spindles 232 for multi-angle machining, thereby significantly reducing the manufacturing cost of the equipment.

The machine tool has the functions of a vertical machining center and a horizontal machining center, and also has the function of milling bevels that the existing vertical and horizontal dual-purpose composite machining center does not have. After adding a first rotary table 120, a tool spindle and a horizontal tool magazine are saved, and the cost of the machine tool is reduced. Then, the vertical and horizontal dual-purpose composite machining center is equivalent to a standard vertical machining center when vertical machining, and is equivalent to a standard horizontal machining center when horizontal machining. The two can be switched freely at any time. Therefore, there is no problem of interference between the horizontal spindle and the workpiece when vertical machining, and there is no interference between the vertical spindle and the workpiece when horizontal machining, which solves the mutual interference problem of the existing vertical and horizontal dual-purpose composite machining center.
