Abstract
The invention relates to a method for fine-machining a bore of a plurality of workpieces and a machine tool unit. According to said method, the workpieces are subjected to fine-hole drilling and precision finishing, preferably roller-burnishing or smoothing, a post-processing measurement is carried out and, depending on said measurement, the fine-hole drilling tool is adjusted.
Claims14
A method for fine-machining bores of a plurality of workpieces comprising the steps of:
- fine-bore drilling of a bore of a first workpiece by means of a fine-bore drilling head, precision finishing of the bore preferably by means of a smoothing or roller-burnishing tool and comprising a measuring step for testing the dimensional stability of the bore of a first workpiece and appropriate machining of the bores of at least one further workpiece, wherein the measurement is carried out after precision finishing of the bore of the first workpiece, and further comprising correcting a tool adjustment of the fine-bore drilling head on a result of the measuring step after precision finishing.
A machine tool unit comprising a centering means, a fine-bore drilling means, a means for precision finishing and an integrated or external measuring unit for measuring the workpiece and a control which is designed for the fine-bore drilling means to be adjustable depending on the measuring result of said post-processing measurement.
