Metal Grinding Sub-Applications

  • After welding, you often need to level the weld and smooth the surface. To accomplish this, we recommend using a Cubitron™ II fibre disc, flap disc, or depressed center grinding wheel. This allows you to quickly remove the weld and create a level surface.

  • Beveling is done to shapes edges of your workpiece prior to welding. This can be done using either a fibre disc, flap disc, depressed center grinding wheel, or even with an abrasive belt. Our selection of metalworking abrasives can help you take the edge off of any metal part or substrate.

  • When precision is not only expected, but required, trust 3M abrasives to deliver. We have the products and expertise to support and improve your precision processes – including centerless grinding, creep-feed and surface grinding, gear grinding, microfinishing and more.
