Low Stress Grinding. For Quality Production,

It has been known for many centuries that grinding can 'burn' metal and reduce its strength. Beginning in the 1940's this knowledge was quantified as seen by the example of the fatigue strengths produced by grinding AISI 4340 steel, quenched and tempered to 50 r sub c: (1) Low stress grinding 102 KSI; (2) Conventional grinding 75 KSI; and (3) High stress grinding …
