LATHE FOR PIPE MACHINING AND METHOD OF PIPE MACHINING AT SAID LATHER Russian patent published in 2014 - IPC B23B5/08 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly, to semiautomatic single-spindle lathes and method of turning. Lathe can turn simultaneously the pipe by outer and inner cutting heads fitted inside lathe saddle and is equipped with the rest for retaining of pipe in saddle body. Note here that inner cutting head is fitted on holder secured at saddle rear end. At least one outer cutting head is arranged on saddle inner wall at least at one support therefor. Proposed method consists in that turning of inner and outer surfaces of workpiece by two cutting heads at a time.

EFFECT: pipe with thin-wall, high geometrical precision, low roughness, higher efficiency.
