Hypereutectic aluminum is saturated with silicon particles that must be exposed during honing. A two-stage process first hones a cylinder’s wall to a mirror-like finish and then relieves aluminum around the silicon particles.

How to Hone an Atypical Aluminum Alloy

Hypereutectic aluminum used for engine blocks contains silicon particles that must be exposed during cylinder honing. This can be done using a cushioning, elastomer honing tool that allows individual abrasive particles to “bounce” over the silicon particles.

Precision Hole Making At High Cpk

Many shops and plants are moving from manual honing machines to CNC honing machines, as well as to robotically automated cells capable of controlling holes size to accuracies of 0.25µm (0.00001 inch). The inherent accuracy and process stability of honing have promoted this changeover because precision parts produced today must meet high Cpk requirements.Honing can produce a specified finish and a desirable crosshatch pattern on the bore surface, which helps retain a lubricating film for sliding components. Makers of outdoor power equipment, motorcycles, ATVs, hydraulics, pneumatics, gears, and valves are some of the users who have "discovered" automated honing in their drive to make parts with tolerances as tight as ±0.0002 inch (±5 µm) at high Cpk levels.
