Blanchard grinding is best suited for single-sided material removal and grinding applications too large for double-disc grinding. Blanchard grinding, also known in the industry as rotary surface grinding, quickly removes stock from one side of a part. DIX Metals uses Blanchard grinding machines for standard surface grinding of large and small sheets and plates, and more.

Some of the advantages of Blanchard grinding include:

• Parallelism and flatness tolerances to .001"
• Elimination of mismatches possible in fly cutting
• Part-to-part thickness consistency
• Ability to re-machine multiple parts for greater economy
• Size versatility
• Surface finishes to 63 Ra

While ideal for large parts like mold plates, rotary tables or vacuum chambers, Blanchard grinding can also be an effective method for simultaneous grinding of multiple smaller parts. Pre-machining costs and turnaround time can be greatly reduced by Blanchard grinding multiple parts, which also serves to eliminate mismatches.

The main feature of our Blanchard grinding operations is heavy stock removal rates for all magnetic or non-magnetic materials. When a substantial amount of material has to be removed, Blanchard grinding proves to be the more cost-effective solution. Using significantly greater horsepower (200hp) than other grinding methods, Blanchard grinding removes large amounts of stock quickly and efficiently. (Non-ferrous parts are handled at slightly lower production rates due to the holding requirements.) A host of materials can be ground using the Blanchard grinding method. Those materials include:

Aluminum Bronze Steel Raw metal Ferrous or non-ferrous

Kirksite Stainless Steel Tool Steels Cast Iron

The Blanchard grinder is known for leaving its trademark cross-hatched surface finish pattern, typically within a 32-125 RMS range, though higher finishes are possible. Items frequently ground are:

Plate stock Rectangular bar stock Die blocks Forgings

Castings Stampings Burnouts and weldments

Dix Metals offers a broad selection of rotary surface and double disc grinders including six Blanchard grinding machines. Each of our six Blanchard grinding machines has the ability to offer dimensional tolerances to ±.001", parallelism to .001", and flatness to .001" in order to meet exacting precision standards. We currently house one 84-inch, one 66-inch, one 60-inch, two 42-inch, and 36-inch Blanchard grinders to meet your needs.
