Metallographic Abrasive Grinding

Soft ferrous metals are relatvely easy to grind with the depth of deformation being a major consideration. 240 grit SiC abrasives provide a good initial start with subsequent use of 320, 400, 600, 800 and 1200 grit SiC. Hard ferrous metals require more aggressive abrasives to achieve adequate material removal.

Why does grinding steel create sparks but aluminium doesn't?

If you are welding aluminium, it is necessary to wire brush the area to be welded immediately before welding (arc welding only on aluminium) so that the electrode can actually contact the metal instead of the extremely thin but strong layer of aluminium oxide on the surface. When aluminium is ground, it will become very hot, just as steel does.

Metallographic grinding and polishing insight |

The basic process of mechanical specimen preparation is material removal, using abrasive particles in successively finer steps to remove material from the surface until the required result is achieved. There are three mechanisms for removing material: grinding, polishing, and lapping.

Grinding of nonferrous metals using loose abrasive grains ...

In engineering industries, grinding is the most common technique used to improve the surface finish of many metals and alloys. Ordinary grinding of some metals and alloys such as aluminum, copper, brass and babbitts is difficult. Wheel clogging on the grinding of such metals causes rapid wheel breakdown and frequent dressing of the wheel is required.
