Since this process also uses the brittle mode, micro-cracks called chippings are generated on the front and rear sides of the wafer. As a countermeasure for this problem, dicing before grinding (DBG) process is also applied. In this process, as shown in Fig. 2, grooving (half-cut dicing) is performed from the front side before grinding.

Grinding Machining Process : Complete Notes - mech4study
The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
