Blanchard grinding is used to quickly remove stock from one side of a large part. Typically, ferrous metals are subjected to the Blanchard grinding process, since the part is often held in place by a magnetic chuck as it is ground.
In a Blanchard grinding machine, the grinding wheel is mounted on a vertical spindle, and moves in a direction counter to the rotation of the magnetic chuck. The tolerances provided by Blanchard grinding machines can be as little as one-thousandth of an inch, with similar flatness. Tolerances, however, vary between materials and work pieces. 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.
