DETAILED DESCRIPTION

[0029] In order to more clearly explain the overall concept of this application, the following Figure 1-2 This application is described in further detail.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features in each embodiment may be combined with each other without conflict.

[0031] The present application embodiment discloses a CNC cutting machine. Figure 1 and Figure 2 A CNC cutting machine includes a bed unit 100, a gantry unit 200 and a head unit 300. The bed unit 100 includes a bed 400 and a workbench 500 connected to the bed 400; the gantry unit 200 includes two support seats 210 and a crossbeam 220 between the two support seats 210, the two support seats 210 are slidably installed on both sides of the bed 400, and the crossbeam 220 is located above the workbench 500; the head unit 300 is connected to the crossbeam 220. The workbench 500 includes a table 510, the table 510 is hollow, a plurality of adsorption holes 511 are opened on the table 510, and a partition 512 is arranged inside the table 510 for dividing the internal space of the table 510. The partition 512 divides the interior of the platform 510 into multiple chambers. The multiple chambers are connected to the outside of the platform 510 through the adsorption holes 511 located above the partition 512. The multiple chambers are connected to multiple vacuum pumps respectively. The multiple vacuum pumps are arranged in a one-to-one correspondence with the multiple chambers.

[0032] The interior of the table 510 is divided into a plurality of independent chambers by utilizing a partition 512. The plurality of chambers are connected to the outside of the table 510 through adsorption holes 511 located above the plurality of chambers, respectively, thereby forming a plurality of adsorption areas on the surface of the table 510. The plurality of chambers are independently connected to a vacuum pump. When the workpiece is adsorbed and fixed, the corresponding vacuum pump is started according to the adsorption area covered by the workpiece, thereby improving the stability of the adsorption and fixation of the workpiece.

[0034] By utilizing a partition 512 to divide the interior of the table 510 into a central chamber 513 and at least one peripheral chamber 514 surrounding the outside of the central chamber 513, a central adsorption area and at least one peripheral adsorption area are formed on the surface of the table 510. When the workpiece is adsorbed and fixed, the central adsorption area is located in the middle of the workpiece, and then the corresponding vacuum pump is started according to the adsorption area covered by the workpiece, so that the force on the workpiece is more uniform, thereby further improving the stability of the adsorption and fixation of the workpiece.

The upper end surface of the blocking net is flush with the upper end surface of the table 510, which reduces the possibility of debris generated by processing accumulating at the adsorption hole 511, thereby avoiding the possibility of affecting the adsorption effect.

The exhaust pipe is used to collect the air exhausted by the vacuum pump, and then the bag dust collector is used to centrally process the air exhausted by the vacuum pump, thereby reducing the possibility of affecting the surrounding environment during the use of the machining center.

After the workpiece is processed, it moves toward the collecting port 521, and during the movement, the debris on the table is pushed into the collecting port 521, and the debris is collected by the collecting bin 530, thereby improving the environmental protection property of the cutting machine.
