ステンレス鋼の重研削の進行に伴う研削特性および砥粒切れ刃状態の変動について

抄録

In this research, a snag grinding was performed on a 410 stainless steel with two different alumina wheel types under constant load, using a specially made grinding machine. The variation of grinding characteristics such as metal removal rate and grinding force with the progress of grinding has been studied. On the other hand, the protrusion height and wear flat area of abrasive grains on the working surface of wheel were measured to discuss the results obtained on grinding characteristics. A close correlation was found among the variation of abrasive protrusion height, metal removal rate and tangential grinding force. Also, it was known that the wear area of grains increases with increasing grinding time. The attritious wear was accompanied with reductions of metal removal rate and tangential grinding force. Self-sharpening recovered the abrasive protrusion height and diminished the percent wear flat; this enhanced to improve the metal removal rate and a cutting action by an individual abrasive grain.
