Traditional surface treatment processes often involve manual hand-held grinding tools, resulting in low efficiency and poor surface quality consistency. Furthermore, the carbon fiber dust emitted during grinding can not only cause short circuits in precision instruments but also pose a significant risk to the respiratory health of operators.

[0019] Four slide rails 4 are provided in total, and the four slide rails 4 are distributed in a cross shape on the support plate 3; the clearance groove 7 is specifically cross-shaped, and the outer diameter of the positioning block 8 is larger than the maximum groove width of the clearance groove 7.

[0026] Working principle: During operation, the carbon fiber composite material workpiece to be ground is first placed on the base plate 1.

Figures 1 to 2 , Figures 3 to 5The positioning block 8 clamps the workpiece. Then, the drive motor 25 is started to rotate the grinding block 12, while the lifting cylinder 20 pushes the lifting plate 9 downwards, causing the grinding block 12 to contact the workpiece surface for grinding. Dust generated during grinding is blocked by the dust cover 13 and, under the action of the dust extraction fan 22, is drawn into the dust collection box 14 through the dust extraction pipe 21. After being filtered by the filter screen 23, it falls into the dust collection box 24. After grinding is completed, the lifting cylinder 20 moves the grinding block 12 upwards, and the positioning cylinder 15 resets, releasing the positioning block 8, allowing the workpiece to be removed. This invention achieves synchronous radial movement of the slide table 5 by linking the support plate 3, slide rail 4, and positioning drive mechanism, using the positioning cylinder 15 to push the linkage plate 16 and hinged connecting rod 18. This drives the positioning block 8 to quickly clamp the workpiece, resulting in fast positioning speed and good effect, effectively improving work efficiency. The lifting cylinder 20 drives the grinding block 12 to feed vertically, and the drive motor 25 precisely controls the speed to ensure consistent grinding trajectory, effectively improving the surface consistency of materials and product quality. By setting up a dust cover 13, a dust suction pipe 21, and a dust collection box 14, dust in the grinding area can be captured in real time, effectively reducing the dust concentration in the work area and preventing dust from harming precision equipment and personnel's respiratory system.
