Rockford Slide & Swing-Aside Shields - SSA-200

INTRODUCTION

These shields protect operators when machining
either small workpieces or large castings that
sometimes overhang the milling machine table. At
the same time, they can provide immediate and
complete access to the workpiece or casting being
machined by sliding or swinging aside the door(s),
as illustrated.



THE SHIELD

The transparent portion of the shield is constructed
of impact-resistant polycarbonate. The
frame of the shield is made of 1" x 2" extruded
aluminum. The shield has front sliding panel(s)
and two side fixed panels. The side panels are
attached at both ends of the table.
These assemblies can be mounted or removed in
a matter of minutes by using two locking T bolts
with nuts.
Each of the front panels can slide to the right or
left and swing aside on their own axis out of the
way (see drawings).
The advantage of the slide and swing-aside movement
is that you can obtain immediate access to
the whole length of the table for loading and
unloading large workpieces. Although the panels
slide aside, they will not take up any more room
than the actual length of the table itself, because
the sliding and swing-aside action takes place in
one movement by simply lifting a latch.



THE SHIELD CONSTRUCTION

The parallel sliding bars enable the shield to be
adjusted to the distance required from the front of
the table to the shield. The adjustment on these
bars caters to castings or large components which
overhang the table. This adjustment is achieved
by loosening the two socket cap screws at either
end of the table. This permits the complete shield
assembly to be moved backwards or forwards to
the position required.
Where the two front panels or the front and side
panels come together, a safety latch is provided
which holds the panels in place. Prior to opening
the panels, the latch has to be released manually.



There are three sizes of shields available which
cover table sizes up to a maximum length of 76".
On bed-type milling machines, where the table
length is well in excess of 76", it is still possible to
use the SSA-300 shield. In many instances, only
part of the maximum length of the table is used.
If this is the case, the SSA-300 shield would be
suitable as long as the longitudinal traverse used
does not exceed the maximum length of the
shield. For a table length of less than 36", the
SSA-000 shield may be used.



These shields have been generously designed to
give protection to the operator; this will be noted
in dimension H, which gives the height of the
shields. Special height panels are available upon
request.
The standard shield does not provide protection on
the back of the table. The rear shields (below) are
used to minimize coolant splash and flying chips
that may fly out of the back of the machine.



REAR SHIELD ASSEMBLIES

These shield assemblies can be used to protect personnel
from swarf and chips at the rear of the table on both sides
of the machine column. They can be used on milling
machines or other equipment that require these types of
shields. The two 3⁄16" thick polycarbonate panels are
mounted to the frame of the machine with mounts (see
illustration). Each panel has extruded aluminum framing
to hold the polycarbonate in place. The mounts are also
attached to this frame. The assembly is available in two
sizes and includes two shields, one set of mounts, and
connectors. Special sizes are available upon request.
