[0022] When it is necessary for the second spindle assembly 302 and the third spindle assembly 303 to move in the X-axis direction, the first electrical machinery 202 may be started. The output end of the first electrical machinery 202 may drive the X-axis lead screw 203 to rotate continuously, so that the Y-axis guide rail 204 may be enabled to move in the X direction. In a case where the first electrical machinery 202 drives the X-axis lead screw 203 to rotate forward, the Y-axis guide rail 204 may move to the left in the X direction. In a case where the first electrical machinery 202 drives the X-axis lead screw 203 to rotate in reverse, the Y-axis guide rail 204 may move to the right in the X direction.

[0023] When it is necessary for the second spindle assembly 302 and the third spindle assembly 303 to move in the Y direction, the second electrical machinery 205 may be started.

[0024] When it is necessary for the second spindle assembly 302 and the third spindle assembly 303 to move in the Z direction, the third electrical machinery 208 may be started. The output end of the third electrical machinery 208 may drive the Z-axis lead screw 209 to rotate continuously, so that the second spindle assembly 302 may be enabled to move in the Z direction, and so that the second spindle assembly 302 may be enabled to move in the Z direction. In a case where the third electrical machinery 208 drives the Z-axis lead screw 209 to rotate forward, the second spindle assembly 302 may move upward in the Z direction. In a case where the third electrical machinery 208 drives the Z-axis lead screw 209 to rotate in reverse, the second spindle assembly 302 may move downward in the Z direction.

[0025] In this way, by controlling the start and stop of the first electrical machinery 202, the second electrical machinery 205 and the third electrical machinery 208, the user may control the second spindle assembly 302 and the third spindle assembly 303 to move arbitrarily in the three directions including the X, Y and Z directions.

Before the clamping assembly 40 flips the part, the entire clamping assembly 40 may need to be moved to a position of the first spindle assembly 301. At this time, the fourth electrical machinery 211 may be started. The output end of the fourth electrical machinery 211 may drive the first lead screw 212 to rotate continuously, so that the clamping assembly 40 may be driven to move in the X direction. In a case where the fourth electrical machinery 211 drives the first lead screw 212 to rotate forward, the clamping assembly 40 may move to the left in the X direction. In a case where the fourth electrical machinery 211 drives the first lead screw 212 to rotate in reverse, the clamping assembly 40 may move to the right in the X direction.

[0028] As is further illustrated in FIG. 2, the first spindle assembly 301 may include a first support 3011, a fifth electrical machinery 3012 and a turning spindle 3013. The first support 3011 may be arranged on the base 10. The fifth electrical machinery 3012 may be arranged on the first support 3011. The turning spindle 3013 may be rotatably arranged on one side of the base 10 and connected to an output end of the fifth electrical machinery 3012 via a belt assembly. The turning spindle 3013 may be a mechanical spindle, and is configured to fix the part and drive the part to rotate continuously.

[0029] When performing turning processing of the part, the user may fix the part on the clamping assembly 40, and then start the fifth electrical machinery 3012. The output end of the fifth electrical machinery 3012 may drive the turning spindle 3013 to rotate through the belt assembly, thereby driving the part to rotate continuously. At this point, the cutting tool on the third spindle assembly 303 may move arbitrarily in the X, Y or Z directions under the action of the movable shaft assembly 20. When the cutting tool moves to an edge of the part, the cutting tool may continue to move and perform the turning processing of the part. The turning processing may refer that, the part continuously rotates together with the turning spindle 3013, while the cutting tool may perform a linear or curvilinear translational motion, thereby gradually approaching the part for processing.

[0030] As is further illustrated in FIG. 3, the second spindle assembly 302 may include a slide plate 3021, a connecting plate 3022 and a first motor 3023. The slide plate 3021 may be arranged on the Z-axis guide rail 207 and capable of sliding in the Z axis on the Z-axis guide rail 207. The connecting plate 3022 may be arranged on one side of the slide plate 3021 away from the Z-axis guide rail 207. The first motor 3023 may be arranged on one side of the connecting plate 3022 away from the Z-axis guide rail 207. The first motor 3023 may be configured to drive the third spindle assembly 303 to swing.

[0031] The third spindle assembly 303 may not only move arbitrarily in the X, Y or Z direction under the action of the movable shaft assembly 20, but may also swing on the XZ plane under the action of the second spindle assembly 302, so that the cutting tool may swing accordingly. The first motor 3023 may a large drive motor with a compact structure. The first motor 3023 may bear the weight of the third spindle assembly 303 and may maintain positioning accuracy very well under a load.

[0032] The third spindle assembly 303 may include a second support 3031 and a milling spindle 3032. The second support 3031 may be arranged on the output end of the first motor 3023. The milling spindle 3032 may be arranged on the second support 3031 and perform the milling processing of the parts. The milling spindle 3032 may adopt an electric spindle, which may have the advantages of compact structure, high processing accuracy and high rotational speed. The milling spindle 3032 may be configured to perform milling, drilling processing, threading processing and cutting processing, or the like.

[0033] During the milling processing, generally after a first face of the part is machined by turning, the clamping assembly 40 may move to the vicinity of the part and clamp the part. At this point, the cutting tool may cut off the part. After that, the part would be flipped by a certain angle under the action of the clamping assembly 40. Since the milling spindle 3032 is the electric spindle, it may rotate by itself. Under the action of the movable shaft assembly 20, the milling spindle 3032 may move in the X, Y or Z direction. Under the action of the first motor 3023, the milling spindle 3032 may swing on the XZ plane. In this way, in a case where the milling spindle 3032 is continuously rotating and thus driving the cutting tool to rotate continuously, the cutting tool may perform secondary processing of the second face of the part. The milling processing may refer to a case where, it is ensured that the part remains stationary, while the cutting tool continuously moves and rotates.
