Drawing is usually performed at room temperature, thus classified as a cold working process; however, drawing may also be performed at higher temperatures to hot work large wires, rods, or hollow tubes in order to reduce ...
The machine is capable of planning the drill procedure, optimizing its electric power usage, changing drill bits and automatically returning to a charging station when necessary. In addition to the potential for higher productivity, workplace safety is an area where this kind of technology may bring significant improvements.
Rods and bars were either sold, or rods were used to make wires up to 0.0056 inches thin. The wire train started with nine 8 and 10-die tandem drawing machines, followed if desired by one 13-die machine, followed if desired by one of twenty up-to-16-dies machines for the finest wire. Intermediate anneals as necessary.
