The compliant tool holder

son-x offers compliant tool holders for machine tools and industrial robots in order to automate
finishing processes like grinding, lapping and polishing which were conventionally performed
in a manual way or separately in dedicated machines. These processes can be integrated and implemented
in milling machines with the CTHone.

With the CTH|one, surfaces with a tribological, precision mechanical and optical function can be manufactured on geometrically complex molds and tools or on turbomachinery components. The process makes it possible to eliminate milling or machining marks in a reproducible way. The sensitive, flexible pressure module provides a constant, adjustable axial force on the tool. The compliant behavior of the CTH one compensates referencing errors, so that air cuts are avoided and the component is reproducibly manufactured with the desired surface quality. The abrasive tools are commercially available and are very flexible in terms of their cutting geometry.

CTHone technology: HSK-interface, individual finishing process, defined pressure

The tool holder permits surfaces with tribological, fine mechanical and optical functions to be produced on complex tools and molds as well as functional surfaces on e.g. turbo-machine components. Milling marks and machining grooves can be eliminated in a reproducible way.
The range of applications extends from rough grinding to high-gloss polishing. Deburring, grinding, lapping and polishing tools are used.
