Fabrication and Special Finishing Methods
Grinding. In finishing, the dividing line between fine grinding and polishing is not always clear because both involve metal removal. Coarse or rough grinding, like a fine milling operation, removes excess metal from weld beads, flash on forgings, or run-outs on castings. Coarse or rough grinding is also used in centreless grinding of bars.

What is Annealing? A Complete Process Guide - TWI
Alloys are annealed at temperatures of between 300-410°C, depending on the alloy, with heating times ranging from 0.5 to 3 hours, depending on the size of the workpiece and the type of alloy. Alloys need to be cooled at a maximum rate of 20°C per hour until the temperature is reduced to 290°C, after which the cooling rate is not important.
