1 Cutting characteristics of aluminum alloy drilling: Due to the low melting point of aluminum alloy, it is easy to stick the knife under the high temperature pressure of drilling, which causes serious accumulation of debris, hinders the smooth discharge of the cutting, and causes the wall of the hole to fluff. Aluminum alloy drilling is relatively loose, occupying a large volume of space, which is not conducive to excretion, especially when the air is deeper and more male discharge cutting. The aluminum alloy has a small elastic modulus and a large surface friction.

2 Drill grinding points: narrow the chisel edge, reduce the axial force and reduce the drilling load. Increase the back angle, repair the edge, reduce the back friction. Use the drill bit of the polishing groove, or use the oil stone light cutting edge to the front and the back, so that the surface roughness of the knife is less than 0.4 micron to reduce the accumulated amount of debris.

Drilling holes in aluminum alloy can be expressed in the following mouths: drill, hole rough, easy to grow tumors, deep hole removal is difficult, large front angle, gold hole lubrication kerosene.
