REAMING TOOL WITH A GUIDE SHANK

摘要

A reaming tool is capable of reaming out several axially interspaced borings of a workpiece. The reaming tool includes a guide shank that can be clamped into a machine spindle and which can be supported in prepared borings of the workpiece to be machined by using external supporting elements. The reaming tool also includes a reaming head coaxially connected on the front end thereof. In order to be able to easily change a worn tool, the reaming head is connected to the guide shank by an auto-centering clamping mechanism. The supporting elements positioned in the proximity of the clamping mechanism can, during a clamping process, be radially spread outwardly from a smaller dimension to a predetermined diameter guide dimension.
