Smooth Deburring Of Composites
The new range of Tuff Core deburring cutters from LMT Onsrud is designed to cut smooth, straight and burr-free edges in composite materials such as the carbon-reinforced plastics (CFK) used in the aircraft and automobile industries. Two different carbide substrates protect the tools against the abrasive character of composite materials. The tool core’s higher cobalt content is said to guarantee precision, even when faced with demanding tension conditions in the material.
