Tool shank and clamping chuck: Perfect concentricity thanks to a suitable clamping surface
The interaction between the tool shank and clamping chuck is crucial for perfect concentricity when machining workpieces.
An optimum result can only be achieved if the tool shank and clamping chuck are perfectly matched to each other according to the rule of thumb: “Same to same”. In this article, we present the various clamping surfaces HA, HB and HE and explain how the selection of the wrong clamping surface can have an impact on the tool life of drills and milling cutters as well as on component quality.
The milling cutter is perfectly clamped – and yet sudden tool life problems occur during milling. How is this possible? One reason that is often overlooked is the compatibility of the clamping surface and the tool holder. There are three types of clamping surfaces on the tool shank: HA, HB and HE. In this article, we take a closer look at the three clamping surfaces.
