A grinding wheel consists of an abrasive that does the cutting, and a bond that holds the abrasive particles together. There are two types of abrasives. Natural abrasives Artificial abrasives. The number indicating the size of the grit represents the number of openings in the sieve used to size the grain.
it seems to me that mrr in units of volume is a performance parameter and not a grinding condition parameter as eg. doc x feedrate (= specific mrr) or grit penetration depth. 12-10-2021, 04:04 AM #16
For small shops with one grinding machine, it may take time for the knowledge gained in a grinding course to pay for itself. For companies with 50 grinding machines running three shifts, the return is quick. Those companies might consume $40,000 in grinding wheels a month, with millions spent on labor. ...

The correct way to measure concentricity on a grinding machine is 180º from wheel (back side), if the roll is supported on grinding seats. For example, if the grinding seat is out of round this form will be transferred to the roll shell by the grinding wheel. Run-out will not be seen on the wheel side but when a
Grinding Machines Grinding Machines are also regarded as machine tools. A distinguishing feature of grinding machines is the rotating abrasive tool. Grinding machine is employed to obtain high accuracy along with very high class of surface finish on the workpiece.
