What is Blanchard Grinding on Metal Alloys
Blanchard Grinding is also known as Rotary Surface Grinding both terms are used interchangeably for the same purpose of a grinding process that is used to quickly remove stock from one side of a large part. Typically, ferrous metals are subjected to the Blanchard grinding process, since the part is often held in place by a magnetic chuck as it is ground. It is, however, possible to use Blanchard grinding on non-ferrous metals and even plastics, but Blanchard Grinding production rates tend to be lower and costs are higher (due to added setup).
Materials We Blanchard Grind
Aluminum – Stainless – Brass – Copper – Titanium – Plastic – Fineblankings – Stampings – Mold Sets – Fabricated Assemblies – Tapered Configurations – Other Ferrous and Non-Ferrous Metals
Faster Than Disk Grinding Depending Upon the Part Required
Blanchard Grinding leaves a specific finish pattern on surfaces, produced by the nature of the operation, and of the movement of grinding tools across the surface. Technically referred to as rotary surface grinding, the process is ideal for surfaces too large for disc grinding, such as plate stock, die blocks and rotary tables. Although it uses far more horsepower than other grinding services, turnaround time is much faster for certain parts; the process can be used simultaneously on multiple parts, as well, also leading to reduced production times and expense.
Fact About Blanchard Grinding:
Blanchard Grinding gets its name from the Blanchard Machine Company, a specialist in Rotary Grinding machines. The Blanchard Machine Company started producing Blanchard Grinding machines in 1909 in Cambridge Ma.
Blanchard Grinding Tolerances and Movements
In a Blanchard Grinding machine, the grinding wheel is mounted on a vertical spindle, and moves in a direction counter to the rotation of the magnetic chuck. Before grinding, surfaces should be relatively even, without any significant protrusions. The tolerances provided by Blanchard grinding machines can be as little as one-thousandth of an inch, with similar flatness. Tolerances, however, vary between materials and work pieces. Due to the design and operation of a Blanchard grinding machine, it will grind different work pieces to a uniform size, a benefit for extensive production runs.
Blanchard Grinding Sizes
The Blanchard Grinding process is an excellent choice for applications requiring high-production rates and moderate finish accuracy. Steel 1 Company LLC uses a wide variety of Blanchard machines for standard surface grinding of large and small plates, washers and rings, etc.
