THE FLEX-HONE SUPER-FINISHING PROCESS PRODUCES A CONTROLLED SURFACE CONDITION UNATTAINABLE BY ANY OTHER METHOD!

Flex-Hones are resilient, flexible, honing tools with a soft cutting action. Each abrasive globule has independent suspension that assures the Flex-Hone to be self-centering, self-aligning to the bore, and self-compensating for wear.

This low-temperature abrading process exposes the undisturbed base metal structure to produce a long wearing surface. The Flex-Hone process develops a surface which is optically smooth and metallurgically free of any fragmented, amorphous or smeared metal from previous operations.

The resulting “crosshatch” finish is extremely efficient in providing a multiplicity of oil grooves or valleys for oil retention as opposed to the often undirectional or uneven valleys common to the conventional type rigid hone. This crosshatch usually remains as the cylinder wall has been wear-reduced by the Flex-Hone.
