A kind of deep hole processing cutter is shown in Figure of description 1, as existing deep hole processing cutter with harmomegathus function, it has the cutter hub 14 that comprises tubulose, certainly, cutter hub is not strict cylindrical tube, because there are many syndetons on its surface, axial hole is contained at main Shi Qi center, forms a sleeve structure.
Wherein:
Heavy boring section turnover size is minimum, is used for heavy boring processing, is fitted in the cutter head end, i.e. left end in Fig. 1, and the other end is the seat end of cutter, is used for connecting boring bar.This part does not need harmomegathus usually, and cutting force is also larger,, if configure the harmomegathus structure, can affect the precision of heavy boring, and is unfavorable to following process yet.
The heavy boring blade 39 of heavy boring section is equipped with 3 usually, and uniform being arranged on heavy boring cutter hub 4, in order to improve the dynamic stiffness of heavy boring part, axial symmetry side at heavy boring blade 39 is provided with guiding strong 6, form supplemental support, can improve dynamic stiffness, and then improve the precision of processing.
Operation after heavy boring is generally right boring, and therefore, in gang tool, type scraping knife is by assembly.
As shown in Figure 1, scraping section is arranged on the cutter hub 14 of rear side of heavy boring section.Known, for weight reduction, compound tool is processed to the structure of hollow usually, and the part of hollow can be installed other annexes.
