Many industry sectors are increasingly demanding very high quality surface finishes. To address this demand, OPEN MIND offers highly efficient finishing strategies that make optimal use of machine and tool options in relation to surface quality and speed. These strategies are part of the hyperMILL®MAXX Machining CAM performance package.
Finishing planar surfaces was long considered a fully developed process, and the machining times for achieving high-quality surfaces through line-by-line milling with a ball mill were simply accepted. OPEN MIND developed a completely new technology that consists of two elements: the innovative 5-axis tangent plane machining strategy and the conical barrel cutter, which can simultaneously be used as a barrel cutter and a ball mill. For the conical barrel cutter, OPEN MIND changed the form of the finishing tool to feature very large radii – ranging from 250 to 1,500 mm.
The large radii of the conical barrel cutter make step-over distances of 6 and 8 mm possible. The ball mill tip on this barrel cutter is also very well suited for machining corner radii. This means that there is no longer a need to switch cutters in order to finish adjacent areas such as rounded interior corners. Companies that use these innovative strategies and the conical barrel cutter for finishing planes and free-form surfaces enjoy significant time savings of up to 90 percent.
