New Concept on Drills Up To 5/8″ (16mm) for One Shot IT8 Robot Application

Industrial robot applications are going to reduce cost in capital investment and enhancing the capability. A new concept of drill technology is successfully running in composite trailing edge manufacturing for drilling 5/8\mi holes in Composite/Aluminum stacks in IT8 quality. This article characterizes the special features of drilling of CFRP/Titanium and Aluminum stacks. Simplified theoretic models will show how CFRP/Titanium stacks should be machined without scratches and burn marks contacting carbon. Low axial forces and smart chip removal technology are the main characteristics of the drilling tool technology, optimized to reach IT8 quality in one shot operation.
