Hole 202 is processed in processing second.Cutter hub 20 connects the end of knife bar 10, the approximate circular cone structure of cutter hub 20 comprising approximation circle
The cutting portion 21 of frustum outer profile, and relief portion 23 made of cutting surface are opened on cutting portion 21.As shown in figure 5, cutting
The radical length for cutting portion 21 becomes larger along far from 10 direction of knife bar.Relief portion 23 is the axis of a less parallel cutting portion 21
Section.The sum of maximum radial length between cutting portion 21 and relief portion 23 processes the diameter in hole 201 less than first, to allow knife
Body 20 passes through the first processing hole 201.
It, can be by 23 side of relief portion close to the first processing hole when the axis along the first processing hole 201 moves milling cutter 100
201 hole wall is mobile in order to avoid milling cutter 100 collides with hole wall.After milling cutter 100 is moved to 201 bottom of the first processing hole, diameter
Rotated after being overlapped the axis of knife bar 10 with the axis in the first processing hole 201 to mobile milling cutter 100 and move up knife bar 10 into
Row processing.After processing is completed, milling cutter 100 is returned along original route.
Specifically, as shown in Figure 1, knife bar 10 includes sequentially connected fixed part 11, tapered portion 12 and mounting portion 13.It is fixed
The diameter in portion 11 is greater than the diameter of mounting portion 13.Tapered portion 12 is with tapering transition connecting portion 11 and mounting portion 13.Fixed part
11 for being external in processing unit (plant).Mounting portion 13 is for connecting cutter hub 20.The diameter of mounting portion 13 is less than the first processing hole 201
Diameter and mounting portion 13 length be greater than first processing hole 201 depth.
In the present embodiment, along it, circumferentially recess forms multiple card slots 121 in order to grabbing and rotating clamp in tapered portion 12
Hold milling cutter 100.It is appreciated that in other embodiments, card slot 121 can be omitted.
It is appreciated that in other embodiments, knife bar 10 can be other structures, as long as knife bar 10 can be installed on processing
Device simultaneously can extend into the first processing hole 201.
In the present embodiment, cutter hub 20 further includes transition part 25 and reinforcement part 27.25 both ends of transition part are separately connected installation
Portion 13 and cutting portion 21.Reinforcement part 27 is connected to one end that cutting portion 21 deviates from knife bar 10.Cutting portion 21, transition part 25 and reinforcement
It is opened simultaneously in portion 27 and cuts surface formation relief portion 23.
The cutting edge 212 of cutting portion 21 is set to the junction of cutting portion 21 and relief portion 23.Relief portion 23 can be discharged and cut
The cutting swarf generated when cutting.
Transition part 25 becomes larger at a distance from the axis of knife bar 10 along far from 10 direction of knife bar with transition connection cutting portion
