Garant: Solid Carbide Barrel Milling Cutters

Garant’s Parabolic Performance Cutting (PPC) represents a further development of ball-nosed slot drilling and is used above all in machine tool building, toolmaking and die making. The particular feature of PPC tools is the main cutting edge in the profile of an arc of a circle. Compared to a ball-nose slot drill this permits significantly larger effective radii. The result is a line skip up to nine times larger, or a surface quality up to 80 times better. To allow finish machining of even more complex geometries, the Hoffmann Group has now extended its range to include a new stub point conical version for machining flat faces at the bottom area of the workpiece. The precondition for PPC is a 5-axis milling machine and CAD/CAM software which allows the tool geometries to be processed as a data model.
