This application discloses a method for micro-hole machining of aluminum alloys and a gas dispersion disk using this method. The method includes: S1, fixing the workpiece and machining a positioning hole on the machining surface; S2, controlling a first tool to drill a first through hole coaxially with the positioning hole, the diameter of the first through hole being d, satisfying k·d<D, and 0.04D<D-d<0.1D, where k=1.06; S3, controlling a second tool to drill a second through hole coaxially with the first through hole, the diameter of the second through hole being D; S4, grinding the back surface; S5, removing burrs using dry ice treatment. By combining primary and secondary drilling, the primary drilling is used to pre-remove most of the excess material. By controlling the size of the primary drilling, the secondary drilling ensures that it can remove the burrs generated by the primary drilling and reduces the final burr size and amount. Subsequent dry ice treatment greatly reduces burr formation and improves the machining accuracy of the micro-holes.

This invention relates to a method for suppressing intersecting burrs in cross-holes using variable-path, variable-parameter helical milling. The method mainly includes the following steps: performing variable-path helical milling to form a single-step hole with a reaming allowance at the intersection of the cross-holes; and then performing variable-parameter helical milling to enlarge the resulting stepped hole, continuously reducing the burr size by progressively decreasing the removal amount, ultimately obtaining a cross-hole without intersecting burrs. This invention uses helical milling instead of drilling, primarily to change the burr formation mechanism from a cutting perspective, significantly reducing the burr size. Furthermore, the variable-path, variable-parameter method uses the previous burr size as a reference; during the reaming process, the removal amount decreases, and the burr size decreases until it is completely suppressed. The method proposed in this invention can achieve cross-hole burr-free operation, effectively saving labor costs, improving production efficiency, and being more environmentally friendly.
