Brush Research GBD3-1/2 3-1/2" Flex-Hone for Engine Cylinder Heavy Duty. For Any Type and Size of Cylinder The FLEX-HONE Process (Superfinishing) produces a controlled surface condition unobtainable by any other method. It involves finish, geometry and metallurgical structure. A high percentage plateau free of cut, torn and folded metal (with radiused ports). A resilient, flexible, honing tool with a soft cutting action. The abrasive (points) globules each have independent suspension that assures the Flex-Hone to be self-centering, self-centering to the bore, and self-compensating for wear. Specifically, it is a low-temperature abrading process that exposes the undisturbed base metal structure to produce a longwearing surface. It is a method of developing a surface on a metal part which is optically smooth and metallurgically free of any fragmented, amorphous or smeared metal from previous operations. It is accomplished at a low pressure where the "stones" float. See and read the various booklets of actual tests covering almost every situation that will ensure a superior performance in situations depending on surface finish. The particular type of Flex-Hone crosshatch is extremely efficient in providing a multiplicity of oil grooves or valleys for oil retention as opposed to the often unidirectional or uneven valleys common to the conventional type rigid hone. A crosshatch that usually remains as the cylinder wall has been wear-reduced by the Flex- Hone.
& The Flex-Hone® Tool. Brush Research Manufacturing has a long history of solving difficult finishing
problems with brushing technology. Established in 1958, our tradition of research, innovation and
manufacturing excellence has helped solve problems in the sophisticated environments of nuclear energy,
aerospace and computer technology as well as industrial applications. BRM has long been a leader in the
art and science of abrasive surface finishing culminating in the patented Flex-Hone Tool. BRM was one
of the first companies to advocate the critical need for finer surface finishes to optimize machine
performance. Today BRM remains at the forefront of abrasive finishing technology. Our commitment to the
advancement of surface finishing remains as strong as ever and we are constantly experimenting with new
materials and applications. As a full line manufacturer of power brushes, twisted in wire brushes and
the Flex-Hone Tool we stand ready to assist you in finding the best solution to your finishing needs.
