Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1 to 5This embodiment of a CNC grinding machine includes a chip removal assembly and an internal grinding machine, comprising a fixed table 1, with a collection assembly disposed inside the fixed table 1. The collection assembly includes a solid-liquid collection tank 17 fixedly connected to the inner bottom wall of the fixed table 1 and a chip collection device 18 disposed outside the solid-liquid collection tank 17. The chip collection device 18 includes a third drive motor 19 fixedly installed on the side surface of the solid-liquid collection tank 17, a second threaded rod 20 fixedly connected to the output end of the third drive motor 19, a movable frame 21 threadedly connected to the outside of the second threaded rod 20, a connecting frame 22 fixedly connected to the lower side of the movable frame 21, and two magnet blocks 23 inserted into the lower end of the connecting frame 22.

[0028] The fixed table 1 is equipped with a CNC grinding device, which includes a stand 2 fixedly connected to the left side of the upper side of the fixed table 1, a first drive motor 3 fixedly installed on the upper side of the stand 2, a first threaded rod 4 fixedly connected to the output end of the first drive motor 3, a threaded block 5 threadedly connected to the outside of the first threaded rod 4, a first connecting plate 6 fixedly connected to the right side of the threaded block 5, two first electric telescopic rods 7 fixedly installed to the right side of the first connecting plate 6, a second connecting plate 8 fixedly connected to the output end of the first electric telescopic rods 7, a second drive motor 9 fixedly installed to the left side of the second connecting plate 8, and a grinding disc 10 fixedly connected to the output end of the second drive motor 9. The fixed table 1 is equipped with a clamping device for holding materials. The device, the clamping device includes two fixed seats 11 fixedly connected to the right end of the upper side of the fixed platform 1, two second electric telescopic rods 13 fixedly installed on the opposite side of the two fixed seats 11, and an arc-shaped clamping plate 14 fixedly connected to the output end of the second electric telescopic rods 13. A filter plate 15 is embedded inside the upper side of the fixed platform 1. Two guide plates 16 that are compatible with the filter plate 15 are fixedly connected to the inner top wall of the fixed platform 1. A baffle is bolted to the side surface of the fixed platform 1. Two magnet blocks 23 are arranged horizontally. A sliding rod is slidably sleeved on the side of the moving frame 21 away from the second threaded rod 20. The side surface of the sliding rod is fixedly connected to the side surface of the solid-liquid collection box 17. A sliding groove is opened in the inner wall of the upright frame 2. The left side of the threaded block 5 is slidably connected in the sliding groove.

[0029] Example 2:

[0030] Please see Figures 1 to 4 Based on Embodiment 1, a drainage assembly is provided on the side surface of the fixed platform 1. The drainage assembly includes two water pumps 12 fixedly installed on the side surface of the fixed platform 1, and a filter screen is fixedly connected to the suction end of the water pumps 12.

[0031] By adopting the above technical solution, the water pump 12 absorbs the coolant filtered inside the fixed platform 1, and uses a fine filter screen to filter out small debris particles and impurities inside. Then, the dust generated by cutting is effectively mixed and increased in weight by being discharged to the upper side of the fixed platform 1, thereby reducing the pollution of the surrounding area by the dust.

[0032] The working principle of the above embodiments is as follows:

[0033] The object to be ground is placed between two fixed seats 11. The second electric telescopic rod 13 drives the arc-shaped clamping plate 14 to move towards the side of the object to clamp and fix it. The second drive motor 9 starts the grinding disc 10 to rotate. According to the size of the object to be ground, the grinding disc 10 is adjusted laterally by the first electric telescopic rod 7 to grind the lateral surface of the object. Then, the first drive motor 3 drives the threaded block 5 to adjust the vertical height of the grinding disc 10. The debris generated during grinding will fall downwards with the coolant and enter the fixed table 1 through the filter plate 15. The guide plate 16 will cool the object. Coolant and debris are guided to the solid-liquid collection tank 17 for storage. The water pump 12 absorbs the coolant in the solid-liquid collection tank 17 and discharges it from the underside of the fixed base 11. It combines with the dust, increases the weight, and falls into the solid-liquid collection tank 17 for collection. The third drive motor 19 is started to drive the connecting frame 22 on the underside of the moving frame 21 to move linearly in the solid-liquid collection tank 17. When the two magnet blocks 23 inserted on the underside of the connecting frame 22 move, they use their own magnetic force to magnetically attract and fix the debris and dust. Finally, the baffle on the surface of the fixed platform 1 can be opened to remove the debris absorbed by the surface of the magnet blocks 23.

[0034] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
