ATLANTIC :: Double disc surface grinding

Plane-parallel functional surfaces on workpieces are generated most efficiently with the double disc surface grinding process. I.e. two parallel surfaces are machined simultaneously by two grinding wheels arranged in a set. Typical examples include roller bearing rings, piston rings, shims and seals, spacer plates, connecting rods, as well as blades and shearing plates.

The surface lay generated by grinding would cause abrasion to the bearing surfaces if left unpolished. By polishing in the direction shown in either the figure 3 or 4, the surface lay is reversed by the polishing operation removing fuzz created by grinding and leaving a surface lay which will not abrade the bearing surface. Nodular cast iron shafts are particularly difficult to grind and ...
