Grinding Surface Finishing

The surface finishing our customer requested is between Ra 12 to 18 microinch without grinding defect (such as feed line, barber pole etc.). Currently we can only achieve surface finishing is Ra10-12 even less than 10. I seek recommendation on what is the best type of grinding wheel, grinding parameter and coolant should be used
