surface speed of grinding wheel

The wheel speed, in terms of peripheral speed, is commonly in therange of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

    Feb 03, 2017· The Doc Replies: If you want more consistent grinding, maintain a constant surface speed. The basic equation is: new rpm= original rpm × original diameter ÷ current diameter. So, if you were happily running your new 18" wheel at1,800 rpm, once itgets down to 15",run it at 2,160 rpm (1,800 × 18 ÷ 15).
