The anterior angle of 0.15mm, outer peripheral teeth are 0 °, and primary clearance is 3 °~5 °, and secondary relief angle is 10 °~15 °, the end tooth of the segment of cutting of formed tooth 3
Outside than the long 0.02~0.03mm in inside, therefore forming tool can be made to remain smooth, brisk in cutting, Er Qie
When processing annular groove, there is self centering effect, the wherein anterior angle of end tooth is 4 °~6 °, and primary clearance is 3 °~5 °, secondary relief angle
Be 10 °~15 °, margin width is 0.05~0.10mm, the tooth height of formed tooth 3 higher than annular groove to be processed depth value 0.5~
0.6mm, the radial basic size value of the inner circumferential tooth of the segment of cutting of formed tooth 3 are equal to the maximum limit of size value of annular groove to be processed
Margin width with the half of the sum of minimum limit of size value, inner circumferential tooth is 0.08~0.12mm, and primary clearance is 3 °~5 °, secondary relief angle
It is 10 °~15 °.The arc radius that wherein radius of tool arc 31 should be in the root of annular groove to be processed is consistent.
Please refer to Fig.4 and Fig. 5, Fig. 4 be the deep hole end face annular groove forming-tool with 1 formed tooth structural schematic diagram；Fig. 5
For the left view structural representation of Fig. 4.
In order to improve the ease for maintenance of deep hole end face annular groove forming tool, the end in spare portion 2 sets that there are one formed tooths 3.
Certainly, the secondary tooth 6 that the end in spare portion 2 is also provided with one and formed tooth 3 is oppositely arranged, formed tooth 3 it is interior
The size value of all teeth is more than 0.15~0.20mm of the opposite position of secondary tooth 6.Processing annular is namely not provided on secondary tooth 6
