    PLUNGE RATEThis is the speed at which the bit enters the wood. Keep in mind that End Mills are meant to cut from the side whereas drills are meant to cut vertically. You can not plunge an end mill into material like you would a drill bit. For most woods I usually set the Plunge Rate to 10 mm/sec or less.

  • Grinding Media Wear Rate Calculation in Ball Mill

    In any mill the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball
