Deburring tool machines elliptical, contoured surfaces

Heule Tool Corp. has introduced the COFA-C series tooling for deburring elliptical and contoured surfaces in larger diameters.
Replaceable solid-carbide-coated blades for holes from 6 to 26 mm are available from stock, with numerous coatings based on the material being machined. These tools are designed for ID and OD elliptical deburring on even and uneven bore edges in a single operation. They are suitable for automotive and aerospace applications such as forks, yokes, common rails, castings, tubes with cross bores, and other workpieces with cross bores in main bores.
The larger sized C-series consists of an independent blade that is fit into a more rigidly guided blade holder. This increases the tool life and process capability, the company states. Different blade sizes are available for the same tool body, allowing different cutting diameters based on a specific application.
Controlled by a simple spring, the carbide cutting blade follows the contour of the hole’s surface, removing all burrs while creating an even tapered corner break. The blade does not cut as it passes through the bore and will not damage the hole’s surface. The edge break begins only at the point where the blade contacts the material and then tapers the hole’s edge. This allows for faster feed rates because the tool slows itself down as it enters the through-hole.
