Hoffmann Group Expands PPC Tool Family

Hoffmann Group USA’s (Knoxville, TN) parabolic performance cutting (PPC) product line now includes a PPC indexable insert and Garant PPC solid carbide barrel milling cutters for high-alloy and hardened steels. The PPC process represents increased development of ball-nosed slot drill cutting, also known as barrel milling. Primarily used for finishing free-form surfaces in machining tool building, tool making, and die making, the process can achieve up to a nine times shorter processing time or significantly improved surface quality.

With the new PPC indexable insert, which is compatible with the Garant precision copy milling cutters as tool bodies, Hoffmann Group launches an alternative to PPC solid carbide barrel milling cutters with a straight or stub point conical-shaped main cutting edge. The PPC cut-off inserts process flat faces and freely accessible surfaces without interference contours on the 3-axis machine; and are available for steel, high-alloy, hardened steels, stainless steel, and aluminum. Garant precision copy milling cutters, which are suitable as tool bodies, are available in steel and solid carbide versions, including a Garant PowerCard.

The company also has optimized three versions of its PPC solid carbide barrel milling cutter for hard machining. The new tools have a tangential, conical, or stub point conical form and are suitable for finishing flat faces and large surfaces with interference contours as well as deep and hard-to-access cavities. These inserts are especially useful on the 5-axis machine. The Garant PPC indexable milling inserts are also available to users for finishing components made from high-alloy or hardened steels with freely accessible surfaces without interference contours.

The precondition for PPC is a CAD/CAM software coordinated to the milling strategy, which allows the tool geometries to be processed as a data model.
