In shape on step, make the top surface of annular workpieces and the either flush of cyclic annular locating core disk；
4th step is socketed after the impacted bolt in pressing plate sub-assembly is passed through pressure plate fastener and upper gasket across core disk through-hole
Afterwards, it is screwed together after being then passed through lower gasket with nut, keeps annular workpieces and cyclic annular locating core disk fixed；
5th step starts lathe, with levogyrate inner thread lathe tool, the inner hole of turning annular workpieces from inside to outside, in annular work
Levogyrate inner thread is formed on the inner hole of part.
The present invention solves the problems, such as that the lesser major diameter annular element clamping of axial dimension is unstable by cyclic annular locating core disk,
Axial grip is realized by pressing plate sub-assembly, avoids deformation caused by radial force, it is ensured that clamping workpiece is stablized, and positioning is quasi-
Really, in addition, using this axial compression method, workpiece dress, tear open it is also very convenient and efficient, tooling disposably install position after,
Workpiece, which does not need centering, directly to be processed, that is, ensure that processing quality improves production efficiency again, especially produce in enormous quantities
When highly significant.
