Machining process for light metal alloys involves mechanically fine machining surface and setting back softer light metal matrix through thermal rays

摘要

When finishing or machining light metal alloys the surface is machine-polished and then the softer light metal matrix (8) is set back by thermal rays (13) so that the hard material crystals (9) are exposed. The wave length of the rays directed onto the surface being processed lies within the absorption gap of the hard materials.
