Metal Workpiece

Metal Workpiece. metal rollers typically consists of a set of three steel rollers that are arranged with the long rolling axes parallel and the rolling centers of the three forming a triangle (See Diagrams/Illustrations) Often the operator can adjust the spacing between the rollers to engage the workpiece and adjust the amount of.

This metal fabrication process works by manipulating metal to bend at an angle The most common means is with a brake press that creates creases in the metal by pinching it The workpiece is held between a punch and a die and forced to crease with pressure from the punch This process is usually used to shape sheet metal.

The rollng of hot metal workpieces in a rolling mill including a roughing mill a finishing mill and a mandrelless coiler located between the former two components is accomplished by first rolling the workpiece in the roughing mill then coiling the workpiece in the coiler uncoiling the workpiece from the coiler delivering the workpiece to the finishing mill and rolling it in the finishing mill Author W SmithCited by Publish Year 1972.
