New! Quad-I Forward
Vise
The Quad-I Forward Vise aligns directly to the "X"
and "Y" axes for ++ programming.
It improves all
workholding operations on precision CNC machines and manual
equipment.

What
is the NEW Quad-I Vise?
by
the designer and inventor of the original Quad-I Vise, Stanley
Dornfeld
The
Quad-I Vise was redesigned for the Machinist. Why? Because
all of the earnings coming into the machine shop, come in through
the hands of the machinist first; and Quad-I is here to help
him.
 The
Clamp
The
first order of business was to build a very good clamp. The “Straight
Line Clamping” feature employed in the Quad–I
Vise applies all of the clamping force to hold the part. The
vise is very sensitive to feel. When needing a light
force, a light touch can yield one. When needing a
strong force for holding, the extra clamping force developed
by “Straight Line Clamping” will supply one. The
box way design of the moving jaw has a very close running
fit, less than one thousandth of an inch, yet it still has
a free running slide.
The
Fixed Jaw
The
second order of business was to have the fixed jaw in front,
to align the vise to the machine’s coordinate system. This
is a big advantage in helping the machinist keep his mind
clear of work-a-rounds and confusing extra steps needed to
make accurate parts.
The
fixed Jaw in front enabled other advantages to emerge. The
Acme screw passes through the fixed jaw. The Capture nut
which is attached to the screw applies the clamping force to
the fixed jaw. This same force is also pulling the moving
jaw in to clamp the work. These opposing forces neutralize
each other and create a balance between the two jaws. This
system offsets the pressure against the fixed jaw allowing it
to remain a stable zero reference for repeatability.
