Blanchard Grinder Services

Blanchard grinders are best suited for materials with a large surface area. The distinctive feature of Blanchard grinding is its ability to rapidly and efficiently remove large amounts of material, making it particularly suitable for projects requiring significant stock removal.

About Blanchard Grinders

Blanchard grinding is named after the Blanchard Machine Company, which was founded by Robert Blanchard in the early 1900s. The company was based in Cambridge, Massachusetts, and it specialized in manufacturing a specific type of surface grinding machine that utilized the rotary table grinding technique.

Blanchard Grinder Remanufacturing

Robert Blanchard developed this innovative grinding machine to address the needs of various industries, especially those requiring efficient grinding of large, flat surfaces. The machine’s design featured a rotary table capable of holding and rotating large workpieces, while a vertical grinding wheel passed over the workpiece’s surface. The combination of rotational movement and vertical grinding allowed for the rapid removal of material from the workpiece, resulting in flat and parallel surfaces.

As the company gained popularity for its surface grinding machines, the process they employed became widely known as “Blanchard grinding” due to its association with the Blanchard Machine Company.

Over time, the term “Blanchard grind” became a standard industry term to describe this particular type of surface grinding process, that leaves a cross-hatched design usually found on the finished material surface. Today, many companies and machine shops use Blanchard grinding as a standard method for precision grinding of large, flat parts, and the name has become synonymous with this type of grinding technique.
