Blanchard rotary surface grinding is a process for removing large amounts of material very efficiently on flat surfaces. Blanchard grinding is often more cost effective than milling. We utilize a large variety of abrasives to meet your specifications on ferrous and non-ferrous materials. Using Blanchard grinding we provide flat, parallel and square parts, with tolerances to .001”, depending on size and material. Surface finishes typically range from 32-125 RMS.
