rous. Custom sizes and grits are also available directly from the manufacturer. In the case of Sikorsky, the flexible
hone needed to be constructed with diamond crystal grit. Brush Research offers a diamond flexhone in a variety of mesh sizes that can easily produce finishes on hard materials to a range of Ra of 0.1 to 0.15µm. Sikorsky also need ed the diamond hones in a very small size and large volume. Brush Research produces very slen
der hones for tiny IDs, but also produce tools for use on large jet engines that required hones 1015inches in diame ter. The FlexHone is also in wide use throughout many other industries, including automotive, firearms, machine shops and other types of man ufacturing. For more information, contact Brush
When a legendary helicopter company was confronted with a worldwide problem in cleaning scale from a small outsourced part, it turned to Brush Research’s Diamond Flex Hone.
Diamond ‘Flex-Hone’ Tool Enables Sikorsky Helicopters to Overcome Production Stop
Sometimes the most experienced
technicians or skilled toolmakers need to look to specialists outside when it comes to solving critical service problems. Such was the case when a legendary
helicopter company was confronted with a worldwide problem in cleaning scale from a small, outsourced part that was preventing it from proceeding with production of its helicopters all over the world.
The problem was a
carburized bearing surface delivered by a supplier of Sikorsky Aircraft Corporation, designers and builders of the world's most advanced helicopters for commercial, indus trial, and military use. “We attempted to
remove this scale with a carbide reamer and a diamond lap to no avail,” says Tony

Lawrence, Tooling Services Manager for Sikorsky Product Center Core Services. “The material in question was 9310
[alloy steel], and very hard, around 66RC (Rockwell C scale hardness),” Lawrence explains, which required a tool of equal toughness to do the job properly. He notes that his group had used diamond FlexHones, available from Los Angelesbased Brush Research Manufacturing in a very limit ed set of applications previously, but certainly not for this high volume situa tion they now faced. The FlexHone is a ballstyle tool char
acterized by a shaft with small, abrasive globules that are permanently mount ed to flexible filaments. The tool, which can be mounted in a hand drill motor or a machine tool chuck, is used for finish ing or resurfacing of the hard metals, ceramics and other tough materials used in items such as ports, sleeves, and cylindrical bores. The flexible hone is available in many
sizes with a wide selection of grit materi al, allowing the tool to be matched with a variety of materials from very hard, heat treated alloys to softer, nonfer
