Grinding Brings Large Metal Pieces Down to Size
February 1, 2024
Blanchard grinding is one of a variety of finishing processes that Titletown Manufacturing employs to deliver cost-effective, high-quality parts and projects for original equipment manufacturers (OEMs). Named for the Blanchard Machine Company, which developed the vertical rotary surface grinding machinery more than a century ago, Blanchard grinding imparts a recognizable cross-stitch pattern on stock.
The Titletown Manufacturing team often uses techniques such as Blanchard grinding and flame cutting to bring larger pieces of metal stock into target dimensions. While not as exact as precision grinding techniques, Blanchard grinding can approach tolerances of 0.003" with a typical surface finish of 65 RMS. Higher surface finishes are available on request.
Titletown Manufacturing uses precision grinding machines in its manufacturing assembly services for pieces that require a smoother finish or tighter tolerances. The shop's high level of precision grinding technology can achieve surface finishes of about 10 RMS and tolerances approaching 0.0001".
Depending on the final application, Blanchard grinding may be all that is required to bring some parts into their final size and appearance. Its primary advantage comes in its ability to quickly remove material rather than deliver the ultra-fine finishes common with smaller components.
Blanchard grinding features a rotary table that spins the workpiece beneath an abrasive wheel. The wheel is capable of removing significant amounts of material in a single pass, making it a much more time-efficient choice compared to the multiple passes required of a precision grinder for more intricate pieces.
Blanchard grinding can be used on a wide range of materials, including ferrous metals and nonferrous alloys, even plastics and pieces that feature nonstandard geometries. This makes Blanchard grinding a viable option when our team is working on castings, forgings and other assemblies that require uniformity across diverse surfaces.
