At present, the conventional processing method adopted for high-precision inclined holes on thin plates is to firstly mill the hole opening part flat by a milling cutter, the diameter of the milled part is consistent with or slightly smaller than that of the hole, then drill holes by a drill and finally ream the holes. The method for processing has some defects, and the precision can not meet the requirement. Firstly, because the plate is provided with the small-angle hole, the cutter bar is longer, and the bullet is serious during milling; secondly, when drilling and reaming, the cutter is difficult to be overlapped with the previous milling cutter range, thereby causing the diameter of the hole part to be enlarged and generating out-of-tolerance.
