Homalocephalus section, screw hole is provided with the left side center of the cutter hub, is provided with shoulder hole at the axle center of reamer, shoulder hole is respectively milling
Knife mounting hole and bolt mounting holes, the diameter of milling cutter mounting hole are less than the diameter of bolt mounting holes, the external diameter surface of the reamer
Thick hinge cutting edge, transitional cut sword is followed successively by from left to right and finish reams cutting edge, and the thick thick hinge diameter for cutting with scissors cutting edge, which is less than, to be finish reamed
Cutting edge finish reams diameter, and the reamer is sleeved on reamer construction section, and attachment screw is threadedly coupled with screw hole.
The utility model has the advantages that compared with prior art：
First, the finishing of the utility model design is assembling structure pattern to the assembled reamer of wheel bore, when reamer wears
After tipping, it only need to more renew reamer, avoid cutter and integrally scrap situation, reamer is cylindrical in cutter hub with endoporus location and installation
On, with attachment screw tightly, the Standard precision is high, and coaxial precision is reached within 0.015mm, and installing/dismounting is convenient.
2nd, reamer of the present utility model is the close toothing of 12 teeth, can not only obtain high ream machining efficiency, and
It can effectively ensure that to the suface processing quality after wheel bore ream.
