Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a tool for quickly processing an end face annular sealing groove on a radial drilling machine. Background Art

[0002] The end face annular sealing groove is a commonly used sealing structure on the joint surface of the aluminum alloy box. The O-ring in the end face sealing groove is used to seal the lubricating oil path between the joint surfaces of the box. The width of this type of end face annular sealing groove is mainly between 2 and 3 mm, and the depth does not exceed 3 mm. Currently, the solution of interpolation processing is adopted by a small diameter end mill on a CNC boring and milling machine.

[0003] Since the width of the end face annular sealing groove on the aluminum alloy case is small, the diameter of the end milling cutter processed by interpolation can only be smaller, so the rigidity of the milling cutter is poor. In order to avoid tool damage during processing, only a small processing speed and feed rate can be used, resulting in low processing efficiency of the end face annular sealing groove. Since there are many such end face annular sealing grooves in aluminum alloy cases and there are various specifications, it seriously restricts the improvement of the overall processing efficiency of aluminum alloy cases.
