OPERATING GUIDELINES
Refer to Figure 2.
•
Do not attempt to take heavy cuts. It
may “grab” and ruin your workpiece,
break cutter, or damage equipment.
The choice of cut must be proportional
to rigidity of set up, capability of equip-
ment, choice of milling cutter, and
hardness of workpiece.
•
Direction of feed should always be
against direction of cutter rotation.
•
Avoid vibration during milling opera-
tion. Correct this by using a cutter with
a different number of teeth, by chang-
ing speed of cutter rotation, or by
adjusting feed of cut.
•
Covering the opening over cross feed
screw (Ref. No. 21), in front and back, is
recommended to prevent any chips
from dropping on threads of screw and
on table base.
•
Tighen central set screw (Ref. No. 15) to
secure position if required.
U-CLAMP
•
U-clamp can be used to clamp thick-
nesses up to two inches.
•
Position workpiece; it should rest flat
on table prior to clamping.
•
For clamping, use edge of U-clamp
which is closest to ball joint because a
greater force is created at this edge.
•
Make sure U-clamp can rest on work-
piece and table, with hole in ball joint
over a slot in table.
•
Slide stud with T-nut into slot.
•
Slide U-clamp over stud and into posi-
tion to clamp on as much of the work-
piece as possible.
•
Screw the flange nut onto stud.
•
Make sure T-nut is properly shouldered
in slot and the stud is perpendicular to
table.
•
Tighten flange nut to securely clamp
workpiece.
T-NUT
•
For a proper clamping configuration, T-
nut should be shouldered within T-nut
slot or open slot of work table.
•
T-nut must be connected to threaded
stud. T-nut has thread stops; screw stud
into T-nut until thread stops.
•
With a T-slotted table, studs should be
connected before inserting stud with
T-nut into table.
•
With an open slotted table, studs can
not be connected until after stud with
T-nut is inserted through slot.
MAINTENANCE
•
After completing each milling opera-
tion, clean all chips off table and out of
T-slots with a hard bristle brush.
•
Keep threads of cross and longitudinal
feed screws oiled and free of foreign
matter.
•
Keep table top, all machined surfaces
and moving parts lubricated.
•
Periodically turn handwheels to move
table right and left, back and forth, and
full length of travel. This will keep the
Milling Table in good working condi-
tion.
