The recent installation of a new two stage hone may be the most significant
manufacturing improvement ever made by Saylor-Beall as it has dramatically
improved the performance of our air compressors.
The hone provides for a rounder cylinder with more consistent micro-
finish. It allows the piston ring to seal more closely against the cylinder,
reducing the amount of oil that can pass downstream.
The main advantage of two stage honing is the ability to perform a roughing
operation, then come back and do the finish operation with much more
accuracy. The machine uses CNC control to vary the honing speed, also
switching to different grit stones needed for the finish operation. The machine
also uses a brush final operation to knock off burrs or high spots that might
have remained after the finish operation.
While oil is a necessary evil, necessary to lubricate moving parts, its disposal
can be a maintenance nuisance. Oil has always been an irritating side effect
of air compressors. It often mixes with the compressed air, only to condensate
later in the air system. It can cause valves to stick. It can leak through gaskets.
In today’s more environmentally conscious society, anything to reduce the
impact of oil is considered a plus.
Our two stage hone has been in production since March, 2015. We’ve already
seen noticible improvments in our compressor pumps.
We hope this is one additional thing that adds value to Made in the USA.
