    What is Cylindrical Grinding - Steps in Cylindrical Grinding

    In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel

    What is the formula to find out RPM of cylindrical grinding?

    What is the formula to find out RPM of cylindrical grinding? As the wheel diameter gets smaller, the grinding arc length gets smaller, meaning fewer grits are in the action. If you want to maintain exactly the same chip load, the equation is: new rpm = original rpm (original diameter current diameter)1.5
