Operating Instructions
Standard and StandardFLEX Series vices
STANDARD
and
StandardFLEX
series vices can be aligned on the
machine table horizontally or vertically mounted.
Accurate
positioning
and
alignment
within centesimal tolerances is made
through 16 H7 longitudinal or crossway keys.
It is also possible to align the vice through calibrated ground screws
(Not for 1-2 types)
.
POSITIONING
ALIGNMENT BETWEEN THE CROSS KEYWAY AND
THE FIXED JAW PLATE
Set the vice vertically ensuring that it is perfectly parallel to
the table
A
in both sides.
Then with an indicator check the parallelism of the
keyway and its alignment with the fixed jaw plate.
The clamping
on the machine table can be made through screws from the central groove or through side clamps.
Ideal clamping is through side
clamps
(
Art. 296
).
Two vices aligned through central cross keys or ground screws or side lateral reference points guarantee the same reference and alignment on the fixed jaw
section with accuracy within
0.02mm
.

INSTRUCTIONS FOR CORRECT WORK-PIECE CLAMPING
2-
Position the movable jaw
Art120 / 120A
loosening the 2 set
screws
Art.410
in order to allow the ground ball
Art.361
to lift
and then move the
Art.258
blocking group to the proper position
on the vice base leaving roughly 5 mm space with respect to the
workpiece to clamp. (

)
1-
Ensure that the vice is properly positioned and clamped to the
machine table and that the fixed jaw
Art.120 / 120A
is properly assembled.

Tighten the 2 set screws

and
ensure that the positioning ball

is properly positioned in a
spherical recess.

Be careful that the positioning ball is not pushed in the hole used for the vice
clamping screws. It is also possible to use a proper insert
Art. 291
with spherical
recess in order to prevent bad blocking of the ball.

INSTRUCTIONS FOR PROPER USE
Hard tightening down of the vice to the machine
table by this method is
NOT recommended
as it can distort gap X and prevent the moving
jaw from sliding

Using
Art.1
vices, if the pull down option is required, loosen
by a 1/4 turn of the screws
Art.381 / 382
(
Pic.4
) in order to allow the
jaw plates
Art.230
to run downward getting a perfect clamping of the
workpiece against the vice base.
By loosening the screws a 1/4 of a turn you get jaw plate

Clamp the workpiece by turning clockwise the main spindle Art.360
through the box wrench
Art.375
without using tubes or hammers.
Attention: for the right clamping operation a 1/4 turn of the box wrench
is enough. (

In order to clamp the work-piece in the correct way we recommend
the use of a torque wrench to be adjusted according
to the vice type and the clamping power desired or needed.
WARNING
For increased machining accuracy and longer machine life use the following
instructions:
Set the right torque through a clock indicator positioned on the
workpiece, then proceed with the machining operations.
Clamp next workpieces with the same clamping power.
