in one pass at a roll speed of 50 rev/min. The work material has a flow curve defined by K = 275 MPa and n =, and the coefficient of friction between the rolls and the work is assumed to be Determine if the friction is sufficient to permit the rolling operation to be accomplished. If so, calculate the roll force, torque, and horsepower.

E/One's low speed, high torque, (133 mm) wheel has an inlet velocity of 2 feet/sec ( m./sec), which slowly introduces the debris into the cutter and is less likely to jam, bind, or suffoe. The paddles on E/One's cutter wheel stir the wastewater, which helps keep the tank clean and prevents sediment build up.

Grinding Tool Bits When you purchase a new lathe tool bit, it might have an angle on the end, but it is not properly sharpened for turning. Grinding lathe tool bits is a bit of an art. It takes some practice to get good at it. You need to create a cutting edge that is sharp, extends out so that the cutting edge and not the side of the tool contacts the work, but that still has enough support ...

Roll diameters are constantly changing, so torque and speed must be constantly adjusted relative to changing roll diameters. Tension and speed in the internal zones is much more stable since roll diameters in these zones does not change. However, some control is required to set and maintain desired levels. Web defects, splices, desired machine speeds, machine defects and other variables .

Torque required to provide a certain level of tension to a web is total tension measured across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the
