Flex-Hones for Blending Chamfered Through Holes

Brush Research Manufacturing's new line of specialty Chamfer Flex-Hones are designed to blend and radius sharp edges and remove microburrs on chamfered holes, eliminating stress risers caused by the chamfering operation. Standard Flex-Hone tools are effective on the interior corners (the intersection of the chamfer and the hole wall). These series of tools are more flexible and designed to polish and radius the outer corners (the intersection of the chamfer and flange face) as well as the inner corners and hole. The increased flexibility allows the tool to pass through thin web sections and polish the chamfer on the backside as well. "The Flex-Hone tool eliminates hand finishing operations and produces consistent finishes from hole to hole, part to part," said a company spokesperson.

In the aerospace, automotive, semiconductor and medical sectors, it is vital that fastener through-holes are chamfered and free of metal burrs caused by the hole cutting process to ensure a flawless fit and durability when parts are assembled. "With this in mind, progressive manufacturers are increasingly automating this process by incorporating the Flex-Hone to provide a smooth finish without hand bench work," said the spokesperson. Available in a variety of grit sizes and abrasive types, it is suitable for finishing titanium, Inconel and nickel based stainless steel alloys.
