A rotational machining and quality assurance method for thermally extruded linings of turbomachinery are provided. First, a harder top coating is removed by turning, then the lining is finish-turned to size. During the finish-turning, defined turning parameters are maintained and a cutting force characteristic is quantitatively detected and stored. The force characteristic is compared with predetermined limit values, and, depending on the result of the comparison, the lining is approved for use or is produced again.
