CENTERLINE & GIBS ADJUSTMENT
Centerline Adjustment
T he SCD430 is equipped with a feature that allows for centerline
adjustment. It might not be necessary to adjust the centerline unless
more than one vise is used. If using more than one vise, following the
procedure below to have the centerlines of all the vises in line with one
another:
1. Lightly clamp a parallel block between the jaws.
2. Loosen the lock screw in both of the threaded shaft collars near the
handle end of the vise.
3. Holding the lead screw from turning, rotate each collar until the
centerlines have been adjusted.
4. Tighten threaded shaft collars to holding block while preventing the
screw from turning.
5. Tighten lock screws in both threaded shaft collars.
Adjusting Gibs for Accuracy
The SCD430 also has adjustable gibs in each movable jaw to allow for
maximum accuracy. There are two gibs in each movable jaw and can be
adjusted to provide a close running fit with the center way. For most
applications, one movable jaw should be adjusted to have a close
running fit with the center way; this will become a reference surface.
The other movable should remain loose so it can pivot and adjust for any
non-parallelism of the work piece. The procedure for adjusting the gibs
is as follows:
1. Remove the two slotted head set screws located on the top surface
of the movable jaw. These are just plugs and allow access to gib
adjustment set screws
2. Pressure on the gib is accomplished through the use of a set screw
in the movable jaw. By tightening or loosening the set screw, you
can increase or decrease the amount of pressure applied on the gib.
3. Adjust gib as desired.
- Too much pressure on the gibs will make the screw hard to turn.
- Too little pressure on the gibs will result in a loose movable jaw
that is able to pivot.
- Both the front and rear gibs on each movable jaw should be
adjusted with the same amount of pressure.
4. After the gibs have been properly adjusted, reinstall the two slotted
set screws.
