New Honing Options For Hypereutectic Aluminum Cylinder Bores
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.

Alternate Tool Material For Hogging Large Workpieces
Shops often use either carbide or high speed steel cutting tools for hogging out the large workpieces common to the aerospace and moldmaking industries. While both materials have their advantages and disadvantages, cutting tool manufacturer Precision Cutting Tools says powder metal combines the best features of both.

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.
