Vice
The shearing vice, which is a standard fitting on the TIGER 370 CNC---MR , is
equipped with an anti---chip device, adjustable cross positioning, and is driven by
a pneumatic cylinder known as the volampress. These elements will be dealt with
one by one in the following.
Adjusting the vice play
Any play which develops between the slideway and the slide gibs on the vice must
be compensated by adjusting the grub screws setting the distance between the gib
and lead screw, proceeding as follows:
"
slacken all the locknuts on the grub screws in the slide, holding the screws still
using an Allen key.
"
move the vice to its fully open position.
"
adjust the slight pressure exerted by the grub screws on the gib, starting with
the first two in contact with the lead screw.
"
adjust these two grub screws and tighten the relative lock nuts, keeping the
screws still with an Allen key.
"
close the vice until the other two grub screws coincide with the lead screw.
"
repeat this adjustment on the gib grub screws for the entire length of the
slideway
"
at the end of the operation, use the handwheel to move the slide backwards
and forwards, identifying the zones where the grub screws exert greater pres-
sure on the gib.
"
repeat the adjustments if necessary.
"
tighten or loosen the upper nuts on the supports according to the reading ob-
tained with the standard ruler on the machine work table.
