Secondary
operations
Secondary operations can be divided into three categories: Secondary stamping
operations, secondary machining operations, and secondary finishing operations.
Secondary
stamping operations can be used to produce very small quantities of simple
parts inexpensively. They can also be used to produce small to moderate
quantities
of parts that could have been produced with a progressive die, thus avoiding
the cost of the large die. Secondary operations are the only option to
produce parts whose geometry is suited neither to a progressive die, nor
a compound die (for an example of such a piece, see case
study 7). Finally, secondary stamping operations are frequently the
most cost-effective method of completing a job consisting of a family
of parts (for an example of such a piece, see case
study 5).
The
most common secondary machining operation is tapping. While there are
dies capable of performing crude tapping within the die, we've found these
methods to be unreliable. We use two floating armature tapping machines
and a Procunier multiple-head tapping machine for our production tapping
requirements.
We
offer several methods of deburring and surface conditioning, including
belt grinding, buffing, vibratory tumbling, and barrel tumbling in a variety
of media, wet and dry, and bead-blasting. Other finishing requirements
that we can provide in a turnkey role include plating, anodizing, heat
treating, and passivating.
