Blanchard Grinding | How it works!

Blanchard grinding technically referred to as Rotary surface grinding and/or vertical spindle grinding, is usually used on ferrous metals since it is held by a magnetic chuck as it’s ground, to quickly remove stock from one side of a large part, that is typically too large to be double disc-ground. However, it is possible to use Blanchard grinding on non-ferrous metals and even plastics, but production rates tend to be lower and costs are higher due to added setup time.


Technically referred to as rotary surface grinding, the process is ideal for surfaces too large for disc grinding, such as rotary tables, plate stock, and die blocks. Blanchard grinding leaves a specific finish pattern on surfaces, and from the movement of grinding tools across the surface, produced by the nature of the operation. It uses more horsepower than other grinding services, but the turnaround time is much faster for certain parts. It can be used on multiple parts,  leading to reduced expense and production times.


In a Blanchard grinding machine, the grinding wheel moves in the direction of the magnetic chuck. Surfaces should be even, without any significant protrusions before grinding. The tolerances provided by Blanchard grinding machines can be as little as one-thousandth of an inch. Due to the design and operation of a Blanchard grinding machine, it will grind different work pieces to a uniform size, a benefit for extensive production runs. Tolerances can vary between materials and work pieces, due to manual setup.

Blanchard grinding is an excellent choice for applications requiring high-production rates and moderate finish accuracy.
