Blanchard Grinding
Blanchard Grinding (Rotary Grinding)

U.G.C. uses a wide variety of blanchard grinding machines for standard surface grinding of large and small plates, washers and rings, etc. The main feature of our blanchard grinding operations is heavy stock removal for all magnetic materials. Non-ferrous parts are handled at slightly lower production rates due to the holding requirements. The blanchard will leave its trademark cross-hatched surface finish pattern, typically within a 32-125 RMS range, though better finishes are possible.

Blanchard grinding, technically referred to as rotary surface grinding, quickly removes stock from one side of a part, typically a part too large to be double disc ground. Parts as large as 48″ x 84″ or 60″ x 72″ can be blanchard ground on our largest machine. Dimensional tolerances to ±.001″, parallelism to .001″, and flatness to .001″ are achievable on all our blanchard grinders. Using significantly greater horsepower than other grinding methods, blanchard grinding removes large amounts of stock quickly and efficiently.
