What is a Sunnen honing machine?
Honing machines offer an ultra-precise machining procedure trusted by job shops and high-production manufacturers to create parts that perform at the highest levels of speed and efficiency. No boring or grinding process is capable of delivering such fine levels of roundness, straightness and surface detail.
How does a Sunnen hone work?
How Honing Works. The honing process uses a set of engineered abrasive stones arranged around a tool or mandrel. The tool spins as it is stroked in and out of the bore, while at the same time the abrasive stones are expanded against the wall of the bore.
