Abstract
A new multi-functional laser-guided deep-hole boring tool with a 110-mm diameter is fabricated. It can be used for boring, internal grinding and measuring hole accuracies by fixing a head for each purpose on its leading part. Until now, a laser-guided deep-hole boring tool, which is designed for boring, is fabricated and its performance is examined using duralumin (JIS-type 2017-T4) workpieces. As a result, it is found that the tool can be guided to bore a straight hole and be used practically. In the present paper, performance of the new boring tool is examined by using steel (JIS-type S45C) worpieces. Results show that the new tool can be guided to bore a straight hole.
