Inside diameter (ID) grinding leaves no room for error. It’s an exacting process that requires a high-precision specialized grinding wheel. 3M abrasives for precision grinding and finishing allow for reliable, repeatable ID grinding. Whether your operation requires superabrasives or conventional abrasives, 3M has a custom precision grinding solution to fit your needs.
Our conventional abrasives for ID grinding are available in ceramic, aluminum oxide and silicon carbide minerals. These minerals are chosen depending on the substrate, material hardness and other factors in your operation.
When exploring a new abrasive wheel for ID grinding, it’s important to understand your current and potential grinding performance. The specific material removal rate, also known under the abbreviation Q’w, indicates how many mm3 are removed per second with a 1 mm-wide wheel. This value allows for a direct comparison between different grinding wheels and grinding processes.
Formula for the calculation of Q’w
Traverse grinding 〖Q'〗_w=(a_(e ) x n_(w ) x d_w x π)/60
Plunge grinding 〖Q'〗_w=(v_(f ) x d_(w ) x π)/60
1.0 mm3/mm/s: Good average
1.5 mm3/mm/s: Target value
5.0 mm3/mm/s: High performance grinding with CBN
0.3 mm3/mm/s: Finishing
