Método de rectificado y herramienta rectificadora

In a honing method for machining the internal surface of a bore in a workpiece with the aid of at least one honing operation, during a honing operation, an expandable honing tool is moved up and down within the bore in order to produce a reciprocating movement in the axial direction of the bore and at the same time is rotated in order to produce a rotational movement combined with the reciprocating movement. In the process, a bottle-shaped bore is produced, said bore having, following a bore inlet, a first bore section with a first diameter, a second bore section with a second diameter, which is larger than the first diameter, away from the bore inlet, and a transition section with a continuous transition from the first to the second diameter between the first and the second bore section. During at least one honing operation, use is made here of an annular tool (200) which has at least one annular cutting group (220) having a plurality of radially infeedable cutting material bodies which are distributed around the circumference of a tool body and are designed as honing segments which are wide in the circumferential direction and are narrow in the axial direction, wherein an axial length of the honing segments, as measured in the axial direction, is smaller than the width measured in the circumferential direction, and the axial length of the cutting region equipped with cutting material bodies is smaller than the effective outside diameter of the honing tool. The method is particularly suitable for honing cylinder faces during the production of cylinder blocks or cylinder liners for reciprocating piston engines.
