Blanchard Grinding

Uses distinct rotary motions: the worktable rotates counterclockwise while the abrasive wheel turns clockwise. This process ensures that every workpiece is treated uniformly, yielding consistent size and surface finishes. The technique can be traced back to 1909 when the Blanchard Machine Company introduced the first vertical spindle rotary table surface grinder. This innovation laid the foundation for what we now recognize as ‘Blanchard Grinding’.

Mattison Grinding

Mattison Grinding, employing a reciprocating technique, is frequently the final step in part production. While not designed for aggressive stock removal, the surface grinder excels in precision. It can achieve tolerances measured in the tenths of thousandths and delivers surface finishes that are notably finer than those achieved with a Blanchard grinder.
