R
Remanence or ‘Rest’ Magnetism
Residual magnetism is what is left behind in ferromagnetic materials after the magnetic field is removed. This may be caused by magnetic fields from the immediate surroundings, such as clamping tables, magnetic conveyors or induction heating.
Arc welding, machining processes, cold forming and mechanical vibrations could also contribute to the rest magnetism.
Residual magnetism may have problematic and costly consequences, which can be avoided by the demagnetisation of the material.
Roughness Tester
This is used to check whether magnets and assemblies meet the roughness requirements. It measures the roughness with external probes and gains optimal insight into the surface roughness of grooves and holes in magnet material.
Rumbling
Rumbling is a finishing process that removes oil and burrs off metal parts and components. It can also polish parts to make them shiny and smooth or help remove rust.
