Embodiment 1
[0029] see figure 1 , a method for fine hole processing of glue-containing laminated materials, comprising the following steps:
[0030] a. First use a large-diameter drill to drill the initial holes of the upper material and the middle adhesive layer material in the laminated material, and then use a small-diameter drill to drill the bottom hole of the bottom material;
[0031] b. Then use the boring tool to pass through the upper material, the middle rubber layer material and the bottom material in sequence, respectively expand the aperture of the initial hole and the bottom hole, and then use the reamer for grinding;
[0032] c. Finally, use a boring tool to enlarge the hole diameter of the initial hole of the upper material and the middle rubber layer material and the bottom hole of the bottom material to complete the fine hole processing of the glue-containing laminated material.
