After trimming of the ingot, the surface grinding of the ingot is carried out. Actually the ingots are slightly oversized. Hence with the help of lathelike diamond tool, the ingot is ground to a precise diameter. After grinding the ingot to a precise diameter, generally two flats are ground along the length of the ingot.
