We have 9 Sunnen hones including the new ML-3500 and EC-3500 with tooling which can handle up to 5" dia. Or up to 20" long depending on the part’s requirements.

Our 5 CNC O.D. Grinders can handle parts up to 40" long, 12" diameter. We typically hold tolerances as close as .0002" on the diameter and .0005" on lengths. We run large production quantities as well as small lot/prototype parts. Parts can be run between centers as well as fixtured or held in a collet. Parts with multiple diameters, tapers, and shoulders can be ground accurately and economically.

Our lapping machines are Double-sided and Single-sided Speedfam models ranging in table size from 20" to 64". We mainly use Silicon Carbide abrasive on most of our machines. However, we do use aluminum oxide abrasive for some applications, and diamond in our polishing machines. we can hold tolerances of .0002 in production with flatness requirements of 1 helium light band (.000012") on many parts.The variety of parts that we lap ranges from large hydraulic castings to small ceramic or carbon seals.
