Description

Technical Field

[0001] The invention relates to the technical field of drilling, and in particular to a high-efficiency drilling device for an aluminum alloy frame. Background Art

[0002] When drilling holes in aluminum alloy frames, the chips generated by drilling are often long due to the good ductility of aluminum alloy. Although the existing drill bits have a large chip removal space by setting chip removal grooves, the chips at the cutting edge can be quickly discharged to ensure that the inside of the drill hole is relatively clean; however, after the long chips are discharged, the drill bit is still rotating, and the long chips will be entangled around the drill bit, affecting the drilling quality. When the chips are entangled, the machine needs to be stopped to remove the chips, which affects the processing efficiency.
