Blanchard Grinding

What is Blanchard Grinding, or Rotary Surface Grinding?

Blanchard grinding, also known as rotary surface grinding, quickly removes stock from one side of a part. Blanchard grinding services are best suited for single-sided material removal and grinding applications too large for double-disc grinding.

While ideal for large parts like mold plates, rotary tables or vacuum chambers, this type of surface grinding can also be an effective method for simultaneous grinding of multiple smaller parts.

What are the benefits of Blanchard Grinding Services?

The main benefit of Blanchard grinding services, or rotary surface grinding services, is heavy stock removal rates for all magnetic or non-magnetic materials. When a substantial amount of material has to be removed quickly and efficiently, Blanchard grinding is more cost-effective than other methods because of the significantly greater horsepower used (200 hp).
