[0002] The metal cutting manufacturing device is a mechanical equipment used to cut metal materials into required shapes and sizes. It is widely used in the manufacturing industry. Metal cutting manufacturing is one of the basic processes for processing metal materials. It can quickly cut raw materials into the required basic shapes. Metal cutting manufacturing provides the basic shape of raw materials for the lathe coaxial parts rare metal manufacturing device.

In the high-end manufacturing industry, it can realize efficient and precise metal parts manufacturing.

[0003] A Chinese patent with announcement number CN211135916U discloses a metal curved surface polisher with a reversely connected dual four-axis parallel mechanism. The position of the worktable panel is adjusted by the telescopic parallel motion of the four CNC telescopic rods of the upward four-axis parallel mechanism, so that the workpiece and the hemispherical sealed quartz glass cover on the worktable panel can swing at different angles to achieve a certain processing range. The position of the reverse parallel terminal moving plate is adjusted by the telescopic parallel motion of the four CNC telescopic rods of the downward four-axis parallel mechanism, so that the galvanometer on the reverse parallel terminal moving plate can process the workpiece in a large range. The upward four-axis parallel mechanism is reversely connected in series with the downward four-axis parallel mechanism to form the entire reverse four-axis parallel mechanism, realizing multi-dimensional space cleaning. In general, the dual four-axis reverse parallel mechanism and the galvanometer can move relative to each other to achieve full-range processing of the processed surface. The upward four-axis parallel mechanism and the downward four-axis parallel mechanism realize movement through the control of the control center, and the control center outputs signals to control the fiber laser to output fiber signals to make the galvanometer output laser; however, the existing device is difficult to move the workpiece close to the polishing machine during use, and the frequent manual movement and positioning of the workpiece will increase the processing time and reduce the overall production efficiency, which not only prolongs the processing time of a single workpiece, but also disrupts the working rhythm of the entire production line. When the workpiece is moved manually, it is inconvenient to ensure the consistency of the positioning accuracy each time, thereby affecting the consistency and quality of the final product. At the same time, manually moving the workpiece requires the operator to spend more physical strength and time, increases labor intensity, causes operator fatigue, and further affects the operation accuracy and safety.
