109 The grinding wheel in a centerless grinding operation has a diameter of 200 mm and the regulating wheel diameter is 125 mm. The grinding wheel rotates at 3000 rev/min and the regulating wheel rotates at 200 rev/min. The inclination angle of the regulating wheel is 2.5°. The through feed rate of cylindrical workparts that are 25 mm in diameter and 175 mm long is equal to Parts/minute. (Correct to one decimal place)
