The frame 10 is a rigid structure for supporting the various components mounted thereon. The frame 10 includes a base frame 11 and at least one upright 12 fixed to the base frame 11, and a longitudinal direction of the upright 12 intersects a plane in which the base frame 11 is located. Optionally, the base frame 11 and the vertical frame 12 are arranged at a substantially vertical angle, and the vertical frame 12 is in a frame structure and partially protrudes from the upper surface of the base frame 11; alternatively, the stand 12 protrudes laterally from the base frame 11 to form an approximately "L" shaped structure. The vertical frame 12 partially protrudes from the bottom frame 11 to form a columnar structure, and the number of the vertical frame can be one or two.

The second spindle device 30 is disposed opposite to the first spindle device 20, so that the workpiece 100 can be selectively clamped between the first spindle device 20 and the second spindle device 30. For example, the first spindle assembly 20 holds a first end of the workpiece 100, and the first and second longitudinal axis assemblies 40 and 50 machine the outer surface and a second end of the workpiece 100. After the second end is machined, the second spindle device 30 and the first spindle device 20 are close to each other, the second spindle device 30 clamps the second end of the workpiece 100, the first spindle device 20 releases the workpiece 100, so that the workpiece 100 is clamped and moved by the second spindle device 30, the first longitudinal axis device 40 and the second longitudinal axis device 50 can conveniently machine the outer surface and the first end of the workpiece 100, manual intervention for loading and unloading assistance of the workpiece 100 is not needed, and machining efficiency and machining precision are improved.
The first longitudinal axis device 40 and the second longitudinal axis device 50 are respectively used for processing the workpiece 100, and are arranged at intervals in the axial direction of the first longitudinal axis device 40. The first longitudinal shaft device 40 and the second longitudinal shaft device 50 are slidably connected to the vertical frame 12, and the first longitudinal shaft device 40 and the second longitudinal shaft device 50 can move telescopically along the length direction of the vertical frame 12 so as to adjust different processing positions and achieve flexible processing modes.

The first spindle device 20 and the second spindle device 30 respectively clamp the workpiece 100, and the two devices can mutually cooperate to clamp the workpiece 100, so as to form the automatic reversing machining. The rotation axis of the first spindle device 20 and the projection of the rotation axis of the second spindle device 30 on the stand 12 are overlapped, the rotation axis of the first spindle device 20 and the rotation axis of the second spindle device 30 are at the same height, and when the axes of the first spindle device 20 and the second spindle device 30 move to the overlapped position.
