Grinding is Good

Double Disc Grinding


​Double disc grinding is an efficient method of stock removal that results in very high precision parts. Using opposing abrasives wheels, the double disc quickly removes equal stock from both sides of a part. By grinding both sides, double disc grinding has the added benefit of relieving internal stress on material, making it easier to machine.

Blanchard Grinding


“The Blanchard Grinder is generally recognized as the quality machine tool for surface grinding where maximum production, finish and accuracy are prerequisites.”
from “The Art and Practice of Blanchard Grinding”

Blanchard grinding is the preferred choice for jobs with heavy stock removal, one side grind, or parts too large for a double disc grinder. A rotary surface grinder, the Blanchard rapidly removes material from one side of a part at a time to result in precision parts with the signature crosshatch finish. Our maximum capacity grinder can hold up parts that measure up to 42 inches diagonally.

Boor-Duh-Lay? What kind of name is that? If they changed the name to "Mr Grinding" I could pronounce it better.
