Blanchard Grinding


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. Before grinding, surfaces should be relatively even, without any significant protrusions. The tolerances provided by Blanchard 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 machine, it will grind different work pieces to a uniform size, a benefit for extensive production runs.
