High-Speed Needs for

Stamping Electrical
Components

To meet demands for
exacting tolerances
when processing thin and
exotic-alloy sheetmetal,
stampers need a
high-speed press
designed to overcome
thermal expansion
and off-center loading,
and optimize bottomdead-center repeatability.

o produce parts for the electrical
and electronics industries, stampers
must process thin, exotic materials
and measure production tolerances in
microns. Extremely tight punch-to-die
clearance in the tool also is required.
Without the proper high-speed press,
these exacting conditions can prove
challenging.
To help stampers achieve successful
parts production in this arena, the single most important goal of the press
builder is to design and implement
high-speed press characteristics that
maintain the best possible relationship
between the punch and die. A highspeed press must provide the optimum
environment for the tool, and the stam-

per must have a basic understanding of
these high-speed press characteristics.

Dynamic Accuracy Critical
Dynamic accuracy is the key requirement of a precision or high-speed press
and the essential element that creates
the optimum environment required for
high-quality part production and long
die life. The seven key characteristics of
dynamic accuracy are:
• Elapsed-time die-height variation
• SPM die-height variation
• Start-up die-height variation
• Slide lateral displacement
• Slide tipping
• Component deflection
• Vibration.
