Mar 15, 2003· In short, never overspeed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine''s speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.
In the equation of Time for Cylindrical Grinding Cut Length of Cut = Length of job + OverTravel where, OverTravel equals to cm. And Feed/Rev. = w/2 (for rough cut) or w/4 (for finishing cut).
You can use physics to calculate the amount of torque needed to accelerate (or decelerate) the speed of a spinning disc. Without the ability to change the speed of a disc, it would be impossible for you to watch a movie on your DVD player. Here''s an interesting fact about DVD players: They actually change [.]
