Tool Head

Abstract

A tool head includes a first tool and a second tool disposed circumferentially on the tool head where the tool head has a rotation axis. The first tool of the tool head is an adjustable tool that is axially movable such that an axial position, relative to the second tool of the tool head, is settable.

What is claimed is: 
     
         1 . A tool head, comprising:
 a first tool and a second tool disposed circumferentially on the tool head, wherein the tool head has a rotation axis;   wherein the first tool is an adjustable tool that is axially movable such that an axial position, relative to the second tool, is settable.   
     
     
         2 . The tool head as claimed in  claim 1 , wherein the adjustable tool is disposed with play, or has an adjustment distance, in an axial direction. 
     
     
         3 . The tool head as claimed in  claim 1 , wherein:
 the adjustable tool is a roughening tool;   the second tool is a forming tool; and   the roughening tool follows the forming tool along a direction of advance.   
     
     
         4 . The tool head as claimed in  claim 1 , wherein the first tool and the second tool each have a respective engagement region and wherein the respective engagement region is cylindrical. 
     
     
         5 . The tool head as claimed in  claim 1 , wherein the first tool and the second tool each have a respective cylindrical basic body. 
     
     
         6 . The tool head as claimed in  claim 4 , wherein the respective engagement regions each form a respective effective diameter and wherein the effective diameter of the first tool projects over the effective diameter of the second tool. 
     
     
         7 . The tool head as claimed in  claim 1 , wherein the second tool is radially displaceable. 
     
     
         8 . The tool head as claimed in  claim 4 , wherein the engagement region of the first tool is diamond-coated. 
     
     
         9 . The tool head as claimed in  claim 4 , wherein an axial movement capability and/or a length of the respective engagement regions are/is dimensioned such that the respective engagement regions overlap, or do not overlap, in an end position. 
     
     
         10 . The tool head as claimed in  claim 1  further comprising a drive unit, wherein the first tool and/or the second tool is drivable by the drive unit. 
     
     
         11 . A method for machining an inner surface of a cylinder, comprising the acts of:
 providing a tool head that has a rotation axis and a plurality of circumferentially disposed tools;   inserting the tool head into a cylinder for a purpose of machining a cylinder wall; and   altering an axial position of at least one tool of the plurality of circumferentially disposed tools relative to another tool of the plurality of circumferentially disposed tools for a purpose of setting a machining sequence.   
     
     
         12 . The method as claimed in  claim 11 , further comprising the act of:
 changing the machining sequence for a purpose of withdrawing the tool head from the cylinder.   
     
     
         13 . The method as claimed in  claim 11 , wherein a first tool of the plurality of circumferentially disposed tools is a roughening tool and a second tool of the plurality of circumferentially disposed tools is a forming tool;
 and further comprising the act of:   arranging the roughening tool entirely or at least partly behind the forming tool with respect to a direction of advance.   
     
     
         14 . The method as claimed in  claim 11 , further comprising the acts of:
 machining the cylinder wall for a purpose of applying a surface structure; and   coating the cylinder wall following the machining by the tool head.   
     
     
         15 . A use of the tool head as claimed in  claim 1  to produce an internal combustion engine.
