Procedia CIRP, 2020 Abstract Abrasive belt rail grinding (ABRG) was recently applied to repair the contour of the rail and eliminate the surface damage of the rail. Besides, it is desirable to not only suppress the occurrence of new damage but also to improve driving comfort and reduce wheel-rail wear. The surface roughness of the rail directly affects the contact noise,

Wear Process and Grinding Performance of Coated Abrasive Belts
Journal of the Japan Society of Precision Engineering, 1974 In this paper, wear process and grinding performance of coated abrasive belts are investigated, mainly upon their varying process for grinding time. The experiments are performed under constant force plunge grinding and fixed feed plunge grinding. As parameters expressing the worn state of coated abrasive belts, wear height of grain cutting edges a and

Investigation of the grinding process and infeed control in abrasive belt grinding.
Journal of the Japan Society for Precision Engineering, 1986 定切込み速度の円筒プランジベルト研削実験より,その研削過程の理論的解明を試みた.その結果,切込み初期から加工完了までの半径減少量の変化,ゴムコンタクトホイールの弾性変形回復による研削量などを明らかにすることができた.その研削過程の解明により,初期の段階で切込み速度を速くし,短時間で定常研削状態に到達させ,研削時間の短縮による高能率化を図った.さらに,コンタクトホイールの弾性変形回復による研削量を除去した研削方法を試み,寸法精度を向上させることができた.
