Device and method for finishing workpieces

摘要

The method involves carrying out fine-processing of circumferential surfaces of a workpiece i.e. crankshaft (1), after cutting coarse processing and subsequent partial hardening of the circumferential surfaces. Single-point rotation of the circumferential surfaces is executed by a determined cutting edge (7). Cavities are formed in a surface of the workpiece by using laser-bombardment or electrochemical-etching. Tangential rotation of the circumferential surfaces is carried out, and a main bearing (HL1) is processed by using rotation milling i.e. peripheral milling. An independent claim is also included for a rotating machine for finishing a workpiece.
