Abstract
A boring arrangement is connected to a boring machine equipped with a boring bit for boring a hole in overlapping workpieces. The boring arrangement includes a first sleeve connected to the boring machine, and a second sleeve that is movably connected to the first sleeve so as to allow a relative motion therebetween in a boring feed advance direction. Biasing elements such as springs apply a biasing force between the first and second sleeves so as to exert a pressing force through the second sleeve onto a pressing sleeve connected thereto. The boring bit moves through the interior of the pressing sleeve to bore the required hole in the workpiece. Thereby, the pressing sleeve surrounds the boring site and is seated and pressed against the workpiece with a pressing force that is greater than the boring feed advance force exerted by the boring bit onto the workpiece. A suction arrangement sucks away boring chips and other swarf material arising during the boring process. Thereby, the accumulation of swarf material in the joint areas between the two overlapping workpieces is avoided, and there is no need to separate the workpieces to remove swarf material.
