For example, double disk grinding can achieve surface finishes of up 16 Ra µin (0.41 µm) on aluminum and up to Ra 8 µin (0.20 µm) on ferrous alloys. Flat lapping is another abrasive process often considered an alternative to double disk grinding for tight control of surface finish, flatness, thickness, and parallelism.
As discussed above, conventional surface grinding cannot effectively eliminate the waviness induced by wire-sawing operation. One practically approach to overcome this is to use surface grinding to partially replace lapping, as shown in Fig. 8 …
