Blanchard Grinding and Surface Grinding

Our steel grinding services are among the most productive in the country.  We operate (10) large, Blanchard Rotary Grinding machines.  The largest at 250 HP can handle up to 128″ diameter to 45″ tall.  In addition, we have (4) Large Surface Grinders and (3) Large Reciprocating Grinders. Our largest Mattison Surface Grinder reaches 31″ x 36″ x 200″ and can maintain parallelism tolerances to .001. Our largest Mattison Reciprocating Grinder, affectionately named “Big Green” boasts a 400 HP motor and covers plates 48″ X 200″.  This machine helps us to efficiently grind long steel bars and tool steel bars.  Decarbing Tool Steel is a specialty of this Mattison Machine.  Our operators maintain the equipment to meet tight thickness, flatness, and parallel tolerance requirements.  If you have a project that is larger than the sizes listed please contact us about custom step grinding.
