Abstract
The invention relates to a device (1) for the combined precision turning and honing of a cylindrical borehole (35). The device (1) according to the invention can comprise either only honing stones (29) which can be fed or also cutters (7) that can be fed during machining.
Claims7
A method for machining a cylindrical bore with a device comprising a first machining tool with at least one geometrically undefined cutter and a second machining tool with at least one geometrically defined cutter, wherein the first machining tool with geometrically undefined cutter during machining of the bore is feedable, the method comprising the steps of:
- in step I, machining the bore by the second machining tool with geometrically defined cutter;
- in step II, machining a section of the bore by short stroke honing with the first machining tool;
- in step III, machining the bore by long stroke honing with the first machining tool.
A method for machining a cylindrical bore with a device comprising a first machining tool with at least one geometrically undefined cutter and a second machining tool with at least one geometrically defined cutter, wherein the first machining tool with geometrically undefined cutter and the second machining tool with at least one geometrically defined cutter during machining of the bore are feedable, the method comprising the steps of:
- machining the bore by the second machining tool with geometrically defined cutter;
- subsequently, moving in the first machining tool with at least one geometrically undefined cutter in a radial direction;
- subsequently, machining the bore by long stroke honing with the first machining tool.
