METHOD FOR PRODUCING A ROTOR OF A SCREW COMPRESSOR OR A WORKPIECE WITH A HELICAL PROFILE

摘要

The invention relates to a method for producing a rotor (1, 2) of a screw compressor or a workpiece with a helical profile, the rotor (1, 2) or the workpiece with a helical profile having a number of profiles in the form of groove-shaped recesses (3, 4) running in a spiral manner on the outer periphery thereof, the groove-shaped recesses (3, 4) being fine-machined using a grinding tool (5) for the purpose of generating a precise profile. To be able to produce, in particular, rotors and workpieces having variable pitch along the axial extent of the rotor or the workpiece as precisely as possible, according to the invention, the groove-shaped recesses (3, 4) are fine-machined with a grinding tool (5) which only touches the surface of the groove-shaped recess (3, 4) at one point (P) during the grinding process, the entire surface to be machined being machined by the grinding tool (5) through line-by-line traversing of the surface to be machined.
