Device for clamping deep-drilling tools for automatic tool change

摘要

A clamping device for deep-drilling tools with an axial passage by means of a tool holder contains at least one clamping element which acts on a shoulder of the tool holder. Since lubricant is to pass through the tool holder, the latter has to be pressed with high force against a holding part of a deep-drilling device. In order to obtain especially favourable pressing, provision is made for the clamping elements to be movable in at least two directions.
