The invention relates to a method and a device for the precision machining of crankshafts or camshafts to final size tolerances Rz<10μm, preferably≰5μm and concentricity tolerances≰30μM, preferably 6μm. The crankshafts or camshafts has been machined by a cutting operation and at least partly subjected to hardening. According to the invention, after an initial cutting operation and subsequent hardening to 45 to 60 HRC, preferably 50 to 53 HRC, a final cutting operation is carried out using cutting inserts fitted with CBN or PCD inlets. The device used for this purpose has cutting inserts which are fitted with CBN or PCD inlets, wherein cutting inserts clamped in place laterally, radially and tangentially follow each other alternately.
