Wire drawing
machines
for ferrous & non-ferrous
45
“The successful candidate will have experience in wire
drawing, cabling, bunching, and dies.”
The help-wanted advert posted on an engineering search
engine makes the incidental point that wire drawing is first
among equals. That holds for the plant at large. If the drawing
operation is sub-par, it matters little what else the company
gets right.
That the prospective employer did not construe experience more fully makes
another incidental point. Makers of wire drawing machinery have put so much
technology at the service of the operator that experience has come to mean a
ready familiarity with the equipment as much as with the process.
Drawing wire has always been an exacting procedure. But now, given the control
and reproducibility possible with a state-of-the-art drawing machine, precise
measurements of inlet diameter, bell radius, entrance angle, approach angle,
bearing, and back relief are not ideals – they are realities, every time. The block
rotates evenly, runs true, and pulls the wire at a constant velocity. Elongation is
taken up and any slip compensated for. Automatically.
The interface of man and machine will always call for an experienced person.
The providers of the products and services reviewed here have taken the
guesswork out of the judgment calls.
