Grinding and polishing tools Basic principles Finest working processes in tool and mould making The border between grinding and polishing is not clear-cut and a clear distinction often difficult. Generally, three processes for the fine processing of surfaces can be identified: polishing, lapping and polishing/lapping, all of which are chipping processes with loose grit. These achieve the best roughness values (see page 102). The surface quality achieved with these processes is mainly dependent on the following factors: • Grit size of the abrasive • Working pressure • Work movement • Grading...

2. Grinding and polishing toolsa Grinding and polishing tools Basic principles The theoretical definition of abrasives includes all hard material grits, which are used to achieve stock removal. These are usually applied bound in grinding tools. A distinction is drawn made between natural grits such as quartz, corundum, emery, garnet and natural diamond and synthetic grits such as corundum, silicon carbide, chromium oxide, cubic boron nitride (CBN) and diamonds. Corundum (aluminium oxide AI2O3) The most widely used abrasive is classed according to its hardness and toughness: Regular...

Surface roughnessOverview of the surface roughness of the preliminary processing methods and the different grinding medium grit sizes in linear processing When selecting the correct grit size, a surface improvement by 1.5 roughness classes (coarse surfaces) to 0.5 roughness classes (fine surfaces) should be taken into account. The tips of the wedges of preliminary processing are max. attainable values under good working conditions. The stock removal dimensions are usually higher than the absolute surface roughness (errors in the macrostructure and removal of the erosion skin). It may...

Our best-selling diamond compound. Specially designed for the new types of steel that tools are manufactured in. To be used neat or with just two drops of diamond fluid. Normally, diamond compounds must be used with a large amount of fluid. Using a large amount of fluid, however, has the effect of making the diamond compound runny, so that a lot of it is simply projected away during polishing. joke Magic diamond compound effectively creates a precisely calibrated, blocky diamond grit, which guarantees top-quality polishing. The result is an incomparably high level of removal on all...
