In general, grinding is a process that brings a metal product to the desired condition by altering the finish and shape of the metal part. However, there is a difference in how precision grinding affects a metal versus what purpose Blanchard grinding serves. Understanding these differences will help you choose which type of grinding will better serve your purposes.

What Is Precision Grinding?

When you have a piece of metal that requires more accurate sizing, precision grinding is often the best choice for processing the metal. It will help you flatten or shape the surface of the metal so that it will meet specifications. This is an essential process where the dimensions or shape of the metal must meet exact specifications to within a few thousandths of an inch.

Two methods fall under this category of surface grinding. Horizontal spindle surface grinding involves using a fine, grit grinding wheel that rotates at fast speeds. As the metal touches the spinning wheel, excess material is removed and the size of the metal part is reduced in size. This method is primarily used for flat metal surfaces. Cylindrical grinding involves a similar process, except that it manipulates and shapes round metal parts.

What Is Blanchard Grinding? 

Blanchard grinding gets its name because the Blanchard Machine Company was the first developer of this technique in the early 20th century. It involves a coarser grinding wheel, which processes a larger, flat metal part when precision isn’t as critical. It’s a less delicate process that quickly affects one surface area. It also leaves a grinding pattern that many people consider attractive and appealing. This machining process is used to grind castings, forgings, plates, molds, and dies. Blanchard grinders will use large magnets to hold the metal in place during the grinding process.

Many projects involve plating, grinding, or boring metal parts, which are treatments that require skill and precision. Having been in business since 1946, R.A.
