Bridgeport Puck Ring Mill Grinding Machine

Grinding On Bridgeport Millgrinding On Milling Machine Jun 09 2005 I didnt have anything resembling a proper grinding wheel so I used a couple of mounted stones for a die grinder These were pitiful things around an inch in diameter with 14 inch shanks Naturally my mill couldnt begin to spin these stones up to speed since the max RPM is around 3200
