markb Posted June 28, 2009 Share Posted June 28, 2009 grinding mild steel, 36 grit ceramic, 50 grit ceramic,about 3700 fpm using push stick med. pressure. I have maybe 6hr.s on these belts. They grab like they are sticky and vibrate. Are they just worn.? Quote Link to comment Share on other sites More sharing options...
Glenn Posted June 28, 2009 Share Posted June 28, 2009 3700 feet per minute (if my math is correct) is just over 42 miles per hour. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted June 29, 2009 Share Posted June 29, 2009 I have never had one last 6 hours but I press into them to get er Done. Vibrations are not good, changing speed can normally resolve that, OR you may have a bearing problem. Swap a belt and see if another belt vibrates, if it does you may have to change a bearing, but most likely a belt and/or speed change Quote Link to comment Share on other sites More sharing options...
