Honing is a machining process. A self-centering honing tool such as our Novoflex® honing tools is used for this. Cylindrical or flat inner surfaces can thus be optimized in dimensional and shape accuracy.
Novoflex® honing tools consist of polyamide carrier bristles on a twisted shaft. The tips of the bristles are each fitted with abrasive balls. The balls work their way down to a flat surface in the course of machining. The most frequently used abrasive grit is silicon carbide or zirconium corundum. Many different diameters and grit sizes are available.
Work is done with constant pressure and a low cutting speed. The grinding balls press against the inner surface of the bore. Roughness peaks are thus successively leveled. The tool is used in an oscillating manner. The result is a cross-grinding between 25 and 40°.
For cylinder liners, in particular, a so-called plateau finish is sought. The individual profile sections (plateaus) have a low contact roughness and are therefore particularly slippery. Deeper "grooves" between the plateaus ensure good lubricating oil adhesion.
Osborn’s small diameter ATB™ Novoflex Tools are designed with round, abrasive beads fastened to the end of flexible nylon filaments sized to address smaller applications such as brake cylinders, hydraulics and valve guides. This self-centering tool will conform to the bore surface to provide a consistent, even surface finish over the life of the tool.

Designed with round, abrasive beads fastened to the end of flexible nylon filaments, Osborn ATB™ Novoflex flexible honing tools are ideal for a variety of bore cleaning tasks. Tools create crosshatch pattern for improved oil retention and increased efficiency, and will even provide an edge break not possible with conventional honing stones.

The longer brush length of Osborn’s heavy duty ATB™ Novoflex Tool tackles tough honing projects with efficiency. Silicon Carbide abrasive beads are fastened to durable nylon filaments to allow the tool to conform to the bore surface. Flexible filaments are engineered to provide the correct pressure to create an ideal hone over the life of the tool.
