Effective refining techniques, along with a sound sheet metal rolling process should close up vacancies, break up or eliminate inclusions and provide a sheet metal product with a smooth surface. Edge treatment such as trimming, or fine blanking, can improve edge quality. Sometimes cold worked areas can be machined out.

The effects of cold working on metals are summarised below: (i) The grain structure is distorted and resistance to working keeps on increasing due to the lattice distortion. (ii) Residual stresses are set up in the metal which remains unless they are removed by subsequent heat treatment. When reheating is done below the crystallisation ...

The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

Cold Rolling. Like hot rolling, cold rolling involves passing the metal between a series of rollers, some of which are opposite others, in such a way as to make this crosssection of the metal piece become ever smaller. Since cold rolling is done at temperatures below the recrystallization temperature, the product is less ductile. Extension

Rolling bearings. Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.
