Blanchard Grinding or Rotary Surface Grinding

TMT uses a variety of Blanchard machines for rotary surface grinding of metal plates. The main feature of our Blanchard Grinding operation is heavy stock removal at a fast rate for all magnetic materials. Non-ferrous parts are handled at lower production speeds do to holding requirements. The rotary surface grinding of Blanchard will leave its trademark cross-hatched surface finished pattern, typically within a 32-125 RMS range, although better finishes are possible.
