    摘要: The invention relates to a honing method for machining the inner surface of a bore (110) in a workpiece (100) with the aid of at least one honing operation, wherein during a honing operation, an expandable honing tool coupled with a spindle is moved back and forth inside the bore for generating a lifting movement in the axial direction of the bore, and at the same time, is rotated about a tool axis for generating a rotational movement superimposing the lifting movement. In this way, a bore is generated that is rotationally symmetrical with respect to a bore axis and that deviates from the circular cylinder shape, which bore has a circular cylindrical first bore section (120) and adjacent thereto, has a non- circular cylindrical second bore section (130) having an axially variable diameter. A measuring of the diameter of the first bore section (120) in at least one measuring plane (M1-1, M1-2, M1-3) for determining a first diameter value and a measuring of the diameter of the second bore section (130) in at least one second measuring plane (M2-1, M2-2, M2-3) for determining a second diameter value takes place. An evaluation of the second diameter value takes place using the first diameter value in order to determine actual shape values, which represent an actual shape of the bore. The actual shape values are compared to target shape values in order to determine shape deviation values. A subsequent honing operation is controlled subject to the shape deviation values.

    摘要: In a honing method for machining the inner face of a bore (122) in a workpiece (120) by means of at least one honing operation, an expandable honing tool is used in a honing operation, said expandable honing tool having an expandable annular cutting group (220) having a plurality of cutting material bodies distributed around the circumference of the tool body in an end region of the tool body that is remote from the spindle, the axial length of said cutting material bodies being less than the effective outside diameter of the cutting group with the cutting material bodies fully retracted. The method is characterized by the following steps of: rigidly coupling the honing tool to a work spindle of a machine tool; positioning the honing tool and the bore relative to one another such that a tool axis (212) of the honing tool is coaxial with a setpoint position (SB) of the bore axis of the bore; introducing the honing tool into the bore, with the cutting material bodies retracted, as far as an insertion end position in which the cutting group is located in an end region (123), remote from the entry, of the length to be machined of the bore; rotating the honing tool and simultaneously expanding the cutting group, at or in the region of the insertion end position, as far as a first radial position of the cutting material bodies such that, by material-removing engagement of cutting material bodies with the inner side of the bore, a cylindrical widening (121) of the bore is produced in the end region of the bore, said cylindrical widening (121) being centred substantially with respect to the setpoint position of the bore axis; withdrawing the honing tool from the bore while simultaneously rotating the honing tool such that the bore is widened, starting from the cylindrical widening, successively in the direction of the entry side.

    摘要: The invention relates to a honing method for machining the inner surface of a bore in a workpiece with the aid of at least one honing operation, in particular for honing cylinder running surfaces in the production of cylinder blocks, or cylinder liners for reciprocating piston machines, wherein during a honing operation, an expandable honing tool coupled with a spindle is moved back and forth inside the bore for generating a lifting movement in the axial direction of the bore. At the same time, the honing tool is rotated with a torque transmitted via the spindle for generating a rotational movement superimposing the lifting movement. A bore shape that is rotationally symmetrical with respect to a bore axis and that deviates from the circular cylinder shape, and has an axial contour profile is produced. For generating an axially varying material removal, a length of stroke and/or a lifting position of the lifting movement is changed in at least one variable stroke phase (PH2). The honing method is characterized by a control of the torque (DM) transmitted to the honing tool via the spindle such that during the variable stroke phase (PH2), the torque substantially remains constant.

    摘要: 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.
