Blanchard Grinding

First developed in the early 20th century by Blanchard Machine Company of Cambridge, MA, Blanchard grinding is globally recognized as one of the most efficient methods of finishing flat surfaces. Also known as rotary surface grinding, this process can be performed on nearly any material and is more accurate than most other cutting methods.

Blanchard grinding uses a cylindrical grinding wheel and vertical grinding spindle to remove material precisely and accurately. A flat, magnetic chuck holds the material that needs to be finished and then rotates it, carrying the workpiece under the grinding wheel face. The magnetic chuck’s circular rotary motion ensures there are no end pieces and results in a distinctive cross-hatching pattern.

Blanchard Grinding vs. Precision Grinding

While Blanchard grinding is typically the best choice for high volume projects that feature large surface areas, smaller objects may require an alternative method. Delivering high accuracy to smaller surface areas is best achieved with precision grinding.

Precision grinding refers to several methods that deliver extreme levels of precision. For example, cylindrical grinding is one type of precision grinding. It’s used to develop smooth surfaces on objects. Horizontal surface grinding is another precision technique that involves exposing a component’s flat surface to a rapidly rotating wheel. Generally, all precision grinding techniques involve a wheel to precisely smooth surfaces without leaving patterns or bumps.
