MACHINING TIPS: Critical Aspects to Grinding Surface
Jan 11, 2017· For a cylindrical or surface grinder, the feed-rate is determined by the speed of the table. For a centerless grinder, the feed-rate is determined by the angle and rpm of the regulating wheel. For the grinding of most plastics, a suggested feed-rate is fourteen to thirty-two ft/min (4.27 to 9.75 m/min).
