Terraced knife, third ladder knife are arranged along cutter hub axially spaced-apart；First ladder knife includes U and bores edge blade, U brill center inserts；U bores side
Edge blade, U bore the front end that center insert is securedly mounted to cutter hub；Structure is bored using the U of existing maturation, enhances the effect of drilling
Rate；Second ladder knife includes semifinishing blade, finishing blade；Semifinishing blade, finishing blade are securedly mounted to knife
The middle part of body；Realize half right boring, boring combination；The participation of the participation processing point of a knife and fine boring cutter of half fine boring cutter processes point of a knife along knife
Body has axial distance H, and H is equal to 3 times of amount of feeding f；It ensure that in process, acted on simultaneously there are two cutting force
Cutter hub is avoided because of half right boring of the second ladder and boring combination, and because of allowance asymmetry, and then chip power changes greatly, processing
Middle generation cutter chatter, aperture processing dimension are unstable；Third ladder knife includes chamfering blade；Third ladder knife is securedly mounted to knife
The rear portion of body；Countersink form completes chamfer machining.
The first ladder of the utility model knife, the second ladder knife, third ladder knife along cutter hub axially spaced-apart arrange, spacing distance
Workpiece, the second ladder knife incision workpiece are cut off for the first ladder knife；Second ladder knife cuts off workpiece, third ladder knife incision work
Part；After the first ladder knife drills through workpiece, the second ladder knife semifinishing blade, finishing blade start to process；Workpiece passes through
After semifinishing, finishing, hole is finished size；After second ladder knife machines, third ladder knife chamfering blade starts to add
Work completes workpiece orifice chamfer；Cutting force acute variation caused by avoiding not at the same level while processing, directly avoids processing and shakes
It quivers, ensures processing stability.
The utility model third ladder knife chamfering blade working position is blade side plane, and during semifinishing, blade is
Consume point of a knife；Blade side plane is not engaged in cutting；It is cost-saved, after semifinishing blade to service life, the blade
It can be additionally used in the processing of third stepped chamfers；Chamfering blade processes point of a knife consumption for the second ladder knife semifinishing blade and scraps knife
Piece.
The utility model has the positive effect that：Conventional four steps processing is incorporated to time processing, is in turn avoided in processing
The chatter caused by cutting edge is excessive；Right boring blade uses adjustable holder structure, and modularized design substantially reduces nonstandard knife
The manufacturing expense of tool；Production efficiency is high.
