Abstract
A tool for the cutting machining of precision bores in workpieces, with a first machining step which has at least one geometrically defined cutting edge, and with a second machining step which has at least one honing strip with geometrically undefined cutting edges, is proposed. This is distinguished in that the first machining step has at least three support regions which are arranged at a distance from one another in the circumferential direction and which are designed and arranged such that they are supported on the wall of the precision bore during the machining of the latter.
Claims21
A tool for the cutting machining of precision bores in workpieces, comprising:
- a first machining step with at least one geometrically defined cutting edge,
- a second machining step with at least one honing strip having geometrically undefined cutting edges,
- wherein the first machining step and the second machining step are operable to perform different types of machining, and
- the first machining step has at least three support regions which are arranged at a distance from one another in a circumferential direction and are designed and arranged such that they are supported on the wall of the precision bore during the machining of the precision bore,
- wherein each of the at least three support regions comprises at least one of a guide strip and a geometrically defined cutting edge having a circularly ground chamfer.
A tool for the cutting machining of precision bores in workpieces, comprising:
- a first machining step with at least one geometrically defined cutting edge,
- a second machining step with at least one honing strip having geometrically undefined cutting edges,
- wherein the first machining step and the second machining step are operable to perform different types of machining, and
- the first machining step has at least three support regions which are arranged at a distance from one another in a circumferential direction and are designed and arranged such that they are supported on the wall of the precision bore during the machining of the precision bore,
- the tool further comprising a groove in a base body of the tool and which runs parallel with respect to a center axis of the tool, the honing strip being in the groove,
- wherein the groove has a base and two side faces emanating from the base and is of rectangular design, as seen in cross section, and
- wherein the honing strip has at least one bore for receiving a first regulating device of an adjusting device.
A tool for the cutting machining of precision bores in workpieces, comprising:
