BLANCHARD GRINDING

Nostalgic History behind Rotary Grinding, or rotary surface grinding, commonly referred to as Blanchard Grinding

Beginning in 1909-1910 in Cambridge, Massachusetts, as one of the original, grinding equipment manufacturers with their original "soap stone" grinding wheel machines, Blanchard Machine fabricated over 16,000 Blanchard Grinding machines.  Since then, Blanchard Machine has become synonymously recognized as the quality machining manufacturer of high horsepower, rotary surface grinding machines where maximum production, finest finish, and accuracy of parallelism and flatness are required on raw metal, cast iron, aluminum, bronze or steel parallel surfaces.  The Blanchard Grinders have become so accepted as the leaders in the field of rotary surface grinding that specifications often call for surfaces to be "Blanchard Ground."  Blanchard Grinding is well known for the trademark "cross-hatched" surface finish pattern that comes from the wheel turning motion and the rotational movement of the work piece upon the magnetic chuck, whereby both the leading and trailing edges of the grinding wheel are in contact with the work piece.

Large Surface Grinding

Precision Grinding

Precision Grinding specializes in the surface grinding of steel plate.  For steel plate grinding, including large ground plate, small, specialty ground plates, and precision piece parts, Precision Grinding has two of these most recognized Blanchard grinders. Our No. 54-100, Blanchard Vertical Surface Grinder with 54" head diameter, a 100" magnetic chuck, and a 128" corner-to-corner swing has a vertical height capacity of 47" and can handle up to 14,000 lbs on the table.  Our No. 32-60, Blanchard High Horsepower Vertical Surface Grinder with 32" head diameter, a 60" one piece steel magnetic chuck, and a 61" swing clearance inside the water guards  provides high accuracy and high production repeatability.  We can grind precision proto-types, and we can produce large numbers of parallels, base plates, die plates, quick die change plates (QDC plates,) mold plates, mounting plates, wear plates, liner plates, sub plates, bolster plates and other steel plate fabrication.    We have two 10-ton overhead cranes within this bay in order to move the largest of production requirements, and several more 10-ton cranes within our plant for our steel annealing furnace, for our Avenger II plasma plate cutting machine, for our other plate grinding and plate cutting machines, and for shipping and receiving.  When surface grinding large base plates, machine bases, and large precision ground parts, we can handle your job.  Ground plate is our specialty, and we have some of the largest and most durable precision grinders in North America, along with  some of the most experienced and skilled grinding craftsmen and machinists in Alabama.  Please, call us when you need steel plate processing and custom steel fabrication from beginning to end.

RECIPROCATING SURFACE GRINDING

Mattison Vertical Spindle Reciprocating Grinders

Precision Grinding also has two Mattison 400-S Vertical Spindle Surface Grinders and two Mattison Horizontal Spindle Surface Grinders that are especially ideal for grinding shear blades or shear blade sharpening, for surface grinding machined parts such as cylinder heads or blocks, for small tools, for surface plates, mold plates, stripper plates, die plates, sub plates, and bolster plates, and for general manufacturing and tool room requirements such as regrinding or reconditioning milling machine tables.  Our 36" x 168" Mattison Grinder 400-S has the capacity to produce ground parts up to 24" tall.  Our second, unique, 48" x 200" Mattison 400-S Reciprocating Grinder has further been modified with a 410 HP motor and is fully capable of step grinding up to 240", and in some cases 260".  This 410 hp motor allows us to add pressure while slowing down the feed rate which increases the efficiencies while preventing heat buildup and plate burning.  Again, we produce surface ground parts to incredibly close tolerances near .001, and our production grinders along with our qualified machine operators allow us to grind these surfaces for you right the first time.

GROUND PLATE

With a large in stock steel plate inventory, we can produce most any order of ground plates and ship your order to you within 1 - 4 weeks.  Precision Grinding supplies cut plates, machined plates, ground plates, and finished plates including, die shoes, die plates and quick die change plates, base plates, sub plates, bolster plates, wear plates, liner plates, sole plates, stripper plates, grout plates, and any other kind of steel plate that requires plate cutting, machining, grinding, and/or finishing.  On-site, we have a furnace, specifically for stress relieving and steel annealing.  When you need ground steel plate, including steel grinding or regrinding plate of any type for a new or a reconditioned machine or for any structural plate or any steel part, please, call Precision Grinding at 1-888-We-Grind.  We are a full-service steel plate fabricating facility, and with over 60,000 square feet of space, we can handle your order.
