FINE DOUBLE DISK GRINDING

Fine grinding is an operation where abrasive wheels, parallel and facing each other, grind on opposite sides of a 2-dimensional part. At Northern Industrial Manufacturing we have invested heavily into fine grinding technologies that are world class. While manufacturing in the US, we are capable of producing high quality precision shims at automotive volumes. The purpose of the fine grinding operation is to enhance thickness, parallelism, and flatness tolerances, especially for the 2-dimensional parts like thrust washers, precision shims, and precision spacers.

Northern Industrial Manufacturing’s fine grinding operation uses two abrasive wheels instead of one, so we have the ability to remove materials more quickly than the typical Blanchard grinding, which only grinds one side off per operation.

One of the benefits of the US manufacturing footprint of the Northern Industrial Manufacturing fine grinding operation is that it can be effectively used on a wide variety materials. Another benefit of the fine grinding operation is the minimal internal stress that is applied to the part. Because the two discs grind on the part in opposite directions, they apply very little residual stress, which is beneficial for the stability of the part, especially if the part needs more machining operations to be performed to finish the fabrication process.

Another benefit of the fine grinding operation is that this operation can be somewhat automated and able to reduce the thickness of part at a fast rates. The automated aspect of this operation makes it able to create a clean surface finish and maintain tight tolerances. This makes the double disc operation highly cost effective.

Like all machining operations, the double disc operation has many applications. Some of these applications are in the automotive industry, including high quality precision shims. The double disk grinding operation is used to reduce the thickness of the precision shims as well as reinforcing the flatness and parallelism of the precision shims. This is important as precision shims needs to be stacked within the application or in between parts to control quality of assembly.

Ultimately, fine grinding operation improves and allows manufacturers to control the thickness, flatness, and parallelism tolerances on both sides of a part.
