rail grinding performance

Effects of abrasive material and hardness of grinding

The rail grinding experiments were performed using a rail grinding testing apparatus as shown in Fig. 1. The testing apparatus primarily consisted of three parts grinding wheel (8) rail specimen (9) and control system (1). The grinding wheel (8) was powered by the DC motor (4) and the rail specimen was driven by the servo motor (16).
