Embodiment Construction

[0049] A description of exemplary embodiments of a honing method and of a honing tool that can be used within the context of an embodiment of the invention in the material removal machining of a workpiece having one or more boreholes in the finished machining state follows The lower image has the macroscopic shape of a bottle.

[0050] figure 1 A schematic longitudinal section through one such bottle bore 110 in a workpiece 100 in the form of an engine local (cylinder crankcase) for an internal combustion engine is shown. The borehole is rotationally symmetrical with respect to its borehole axis 112 and extends over a borehole length L from a borehole inlet 114 facing the cylinder head in the installed state to a borehole outlet 116 at the opposite end. It is possible to divide the borehole into three mutually adjacent sections of different functions, which merge in a sliding manner within each other, ie without the formation of steps or edges.

[0051] The first bore portio...

Abstract

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 rotary movement superimposed on the reciprocating movement. In the process, a bottle-shaped bore is produced, said bore having a first bore section with a first diameter after a bore inlet, a second bore section with a second diameter greater than the first diameter away from the bore inlet, and a transition section having a continuous transition from the first diameter to the second between the first and the second bore section. In this case, during at least one honing operation use is made of an annular tool (200) which has at least one annular cutting unit (220) with a plurality of radially adjustable cutting-material bodies that are distributed around the circumference of a tool body and are formed as honing segments that are wide in the circumferential direction and narrow in the axial direction, wherein an axial length, measured in the axial direction, of the honing segments is less than the width measured in the circumferential direction and the axial length of the cutting region equipped with cutting-material bodies is less than the effective outside diameter of the honing tool. The method is particularly suitable for honing cylinder running surfaces in the production of cylinder blocks or cylinder liners for reciprocating piston machines.

Description

Background technique [0001] The invention relates to a honing method for machining the inner surface of a borehole in a workpiece by means of at least one honing operation according to the preamble of claim 1 and a method according to the preamble of claim 6 which can be used for A honing tool that performs the honing method. A preferred field of use is the honing of cylinder faces during the production of cylinder blocks or cylinder liners for reciprocating piston engines. [0002] Cylinder faces in the cylinder block (cylinder crankcase) or cylinder liners of internal combustion engines or other reciprocating piston engines are subjected to severe frictional stresses during operation. During the production of cylinder blocks or cylinder liners, said cylinder faces must therefore be machined in such a way that an adequate lubrication by means of a lubricating film is then ensured under all operating conditions and between parts moving relative to each other The frictional r...
