Abstract

A method for machining ribs or grooves on a workpiece including a shaft () and an air or gas axial bearing () attached to the shaft or forming a part of the shaft. The workpiece is rotated about a longitudinal axis of a centrifugal compressor. All of the ribs or grooves are obtained at once by the machining tool on a workpiece portion driven such that it rotates, by moving the workpiece or the tool holder in a longitudinal direction, the machining tool moving back and forth with a machining position in contact with the workpiece and a position wherein it is not in contact with the workpiece from the beginning to the end of the workpiece portion. Reciprocating motions of the machining tool are synchronised with the sinusoidal program, as well as with the desired, programmed arrangement of the ribs or grooves to be produced on the workpiece portion.
