Surface grinding can provide an 8 rms finish and typically keep a +/-0.0002″ tolerance depending on material specs. We can surface grind parts up to 30″ wide/120″ long.
OD grinding on the Landis, Chevalier, or Brown & Sharpe can make a near perfect cylinder with a tight tolerance and 8-16rms finish.
ID grinding on our Heald typically provides the best true circle finish for bearings and critical holes.
