BLANCHARD GRINDING

Blanchard grinding technology has been around for a long time. Blanchard grinding is also known as rotary  surfacing grinding. This process involves grinding one side at a time of various material types, resulting in extremely flat and parallel surfaces.

Blanchard grinding is recognized by oscillating swirl marks on the top of a part. These marks are the result of a magnetic table rotating at approximately 10 RPM, and grinding wheel segments rotating the opposite way at approximately 800 RPM.

The wheel technology for grinding is much different than the typical machining process. Various types of wheels have been created to suit different needs and requirements.
