The "Two Stone Honing System" developed by the Superior Honing Equipment Co. of
Sarasota, Florida has in tests found their two stone system reduced the cost of
replacement stones by as much as 50% compared to other systems.
This reduction is possible for several reasons. In the Superior system, the
mandrel never wears out and virtually requires no replacement.
There is also a reduction in change-over time, and stone and mandrel inventory
is cut in half.
The stones last up to 10 times longer, and for example; the stone costs per
set are less than 50% of the Sunnen system.
An important added benefit is that the two stone system always runs on center
and therefore hones more accurately.
