[0030] It can be understood that gravity center driving is that driving force of movement part coincides with gravity center position (or coincides on the projection of movement plane), and gravity center driving has better mechanical characteristics, so driving force and inertia force are in the same point when accelerating or decelerating, and therefore no torque is generated.

[0033] The C-axis orthogonal swing head rotates around the axis of the Z-axis moving component as the rotation center, and the A-axis orthogonal swing head swings parallel to the movement direction of the X-axis moving component;

[0034] Further, the C-axis orthogonal swing head and the A-axis orthogonal swing head are in an orthogonal structure, and a torque motor driving structure is adopted to realize the rotation of the machine tool spindle around the Z-axis and the X-axis.

[0035] A machining tool for symmetrically machining the workpiece 3 from both sides is arranged at the end of the machine tool spindle.

[0036] Further, the numerical control device 11 is electrically connected with the bed frame 1, and is used for inputting a control numerical control program and controlling the two groups of five-axis moving components on both sides respectively, so as to realize the synchronous symmetric milling of the workpiece 3 by the machine tool spindles arranged on both sides of the machine tool.

[0037] Preferably, the bed frame 1 is arranged in a fully-enclosed symmetric structure, and has high rigidity and stability.

[0038] The numerical control device 11 adopts a double-channel control mode, controls the five-axis moving devices on both sides in 5-axis linkage, and utilizes the rotary worktable 2 for indexing control, so as to realize the double-side axis linkage and synchronous symmetric milling of the workpiece 3.

[0039] Preferably, the bed frame adopts a four-gantry closed integral frame structure.

[0040] Further, for the workpiece with mirror symmetry or central symmetry, two groups of the same tools can be selected, and the tool paths of the two tools are planned according to the mirror symmetry or the center, so that the cutting contact surface and the cutting force of the two tools and the workpiece in the machining process have symmetry.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
