Blanchard Grinding Benefits
Blanchard Grinding removes large amounts of stock quickly and efficiently because of the greater horsepower over other grinding methods. This results in considerable time savings over surface grinding. As a result, Blanchard grinding is an economical method for finish sizing large steel plate, metal fabrications, and castings – ahead of surface grinding and CNC milling for large plate finishing. Blanchard grinding multiple small parts in batches results in consistent thickness and surface finish, eliminating mismatches.
