Metallography: Part Two :: Total Materia Article

The technique for preparing metal sections can be divided into two groups, those processes involving the use of emery papers and coarse abrasives (grinding) and the subsequent operations using fine abrasives (polishing treatments). Compression-type molding is commonly applied to encase specimens in 1 to 1.5 inch diameter plugs of a hardened ...

An important factor throughout the Coarse Grinding and Fine Grinding Stages is that the scratches be uniform in size and parallel to each other in any one grinding stage. Proper grinding involves rotation of the sample by 90o between stages while the grinding angle must be held constant during the grinding at any one stage.

GRINDING PROCESS

Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed

Eight tips for effective grinding - The Fabricator

If the disc is 0.25 inch thick, then a 0.5-in.-wide wear pattern should be showing on the wheel. If the wear pattern is, say, 0.75 in., your approach is too flat, which means too many of the grinding disc's grains are engaging at once. If the pattern is only 0.25 in. wide, your angle of approach is too high. 6. Keep consistent pressure ...
