Estimating the term…
The invention relates to a method for precision machining of crankshafts or camshafts to final dimensional tolerances Rz<10 μm, preferably ≦5 μm and concentricity tolerances ≦30 μm, preferably ≦6 μm, which have been machined and at least partially subjected to hardening, wherein after the first machining has been carried out and subsequent hardening to 45 to 60 HRC, preferably 50 to 53 HRC, a final machining is carried out by means of at least one milling tool, wherein it is provided that the final machining is carried out by means of cutting inserts made of coated hard metal. The invention further relates to a milling tool for precision machining of crankshafts or camshafts.
A method for precision machining of crankshafts or camshafts to final dimensional tolerances Rz<10 μm, and concentricity tolerances 30 μm, which have been machined and at least partially subjected to hardening, wherein after the first machining has been carried out and subsequent hardening to 45 to 60 HRC, a final machining is carried out by means of at least one milling tool wherein the final machining is carried out by means of cutting inserts made of coated hard metal.
A milling tool for precision machining of crankshafts or camshafts to final dimensional tolerances Rz<10 μm, and concentricity tolerances 30 μm, and at least partially subjected to hardening, using radially and/or axially adjustable cutting inserts, wherein the cutting inserts are made of coated hard metal.
