[0051] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0052] The working state is as follows: The turning head 3, grinding disc 2, and milling head 4 on the operation table 1 are all set with fixed programs according to the processing technology. First, the workpiece to be processed is fixed by the chuck 69. When turning the workpiece to be processed, the servo motor 611 at the end of the shaft rod 610 drives the shaft rod 610 and the chuck 69 to rotate through the driving end of the servo motor 611, and starts the program set for the turning head 3 to process the workpiece on the chuck 69. During the processing, the L-shaped support rod 103 and the baffle 105 cannot descend in the sliding groove 67, so that the workpiece will not shake during the processing. After the turning of the workpiece is completed and milling of the workpiece is required, the driving end of the servo motor 611 is started to drive the threaded rod 62 to rotate. At this time, the slider 63 will move along the track of the chute 61, driving the connecting rod 65, the concave support block 66, and the chuck 69 towards the milling head 4 in the middle of the operation table 1. When the lever 82 fixedly connected to the outer surface of the rotating disc 81 abuts against the L-shaped abutting rod 88, the rotating disc 81 will rotate around the connecting rod 65 as the center. At the same time, the rotating rod 83 will also drive the bevel gear 84 at its top to rotate. During the rotation of the bevel gear 84, it will drive the bevel gear 85 and the driving rod 86 to rotate. Since the driving rod 86 is fixedly connected to the sliding block 68, the concave support block 66 drives the chuck 69 to rotate around the driving rod 86 as the center. When the lever 82 and the L-shaped abutting rod 88 are abutted to a parallel state, the rotating disc 81 just rotates 90°. At the same time, the bevel gear 84 and the bevel gear 85 are used to convert and transmit the acting force to the concave support block 66. At the same time, during the processing, the L-shaped support rod 103 and the baffle 105 do not change, so that the workpiece will not shake during the processing. When grinding the workpiece to be processed, the servo motor 611 at the end of the threaded rod 62 is started. When the abutting rod 104 at the bottom of the concave support block 66 enters the guiding groove 75 opened on the inclined rod 72 in the direction close to the turning head 3, the abutting rod 104 will slide into the cavity 101, and at the same time, it will also abut against the L-shaped support rod 103. The L-shaped support rod 103 will be abutted to the position of the corresponding sliding hole 107 on the sliding block 68. At this time, the rod body of the L-shaped support rod 103 will closely adhere to the inner wall of the cavity 101, so that the abutting rod 104 cannot abut against the L-shaped support rod 103 anymore. At the same time, the spring 106 will also be pushed by the L-shaped support rod 103 to a compressed state. At this time, the concave support block 66 will slide upward along the track of the inclined rod 72, and the concave support block 66 will drive the chuck 69 to slide upward on the outer surface of the sliding block 68. When the abutting rod 104 enters the guiding groove 75 opened on the inclined rod 73 from the guiding groove 75 on the inclined rod 72, the connecting rod 65 will slide in the slider 63 towards the inside of the chute 61. At this time, the concave support block 66 and the chuck 69 will move obliquely between the two grinding discs 2 along the track of the inclined rod 73. When the abutting rod 104 moves along the guiding groove 75 to the end position of the cross bar 74, the F-shaped insertion rod 108 on the operation table 1 will be inserted into the insertion hole 109.In this way, the workpiece will not shake during the milling process. At the same time, the servo motor 611 at the end of the threaded rod 62 is turned off. At this time, the chuck 69 and the workpiece to be polished are moved to the position between the two grinding disks 2. Further, start the two grinding disks 2 to polish the workpiece on the chuck 69. This can facilitate the milling process of the workpiece. Further, by starting the corresponding milling program, the workpiece can be milled. The posture of the fixture can change correspondingly according to different processing methods, enabling the fixture to complete the operations of multiple machining surfaces in one clamping, without the need to frequently replace the fixture or adjust the machine tool, avoiding the time waste of repositioning the workpiece during multiple clamps and the errors caused by manual operation. In addition, changing the unified program of the composite machine tool to a fixed program code for each operating head makes the program logic of the composite machine tool simpler. The operator only needs to pay attention to one program, reducing the operation errors caused by program switching. At the same time, the composite machine tool does not need to switch between multiple programs, reducing the time for program loading and switching, and improving the processing efficiency.

[0053] During the machining of the workpiece, start the spraying mechanism 5 to spray cutting fluid on the workpiece being machined, taking away the heat generated during the cutting process, reducing the temperature in the cutting area, and reducing the thermal deformation of the workpiece and the tool. At the same time, the chips generated during the machining process will be washed into the collection tank 91 by the cutting fluid. In addition, the position of the top opening of the collection tank 91 is arranged in an inclined plane, so that the workpiece chips are more likely to enter the collection tank 91 under the action of the cutting fluid. During the process of the cutting fluid and the workpiece chips entering the bottom of the collection tank 91, the filter holes 93 on the collection drawer 92 filter out the workpiece chips contained in the cutting fluid, making the cutting fluid flow to the bottom end of the collection tank 91. Further, start the pressure pump 95 to transport the filtered cutting fluid into the spraying mechanism 5 through the connecting pipe 94, and the spraying mechanism 5 sprays the cutting fluid onto the workpiece being machined again. When it is necessary to clean the chips, pull out the collection drawer 92 to clean the filtered workpiece chips. Through the automatic chip collection and cutting fluid recovery, the downtime caused by cleaning the chips and replacing the cutting fluid is reduced. At the same time, the chips are cleaned in time, avoiding the interference of chip accumulation on the machining process, and improving the continuity and stability of the machining.
