Do not remove more than one setup finger at time as this can allow the
machine to slip in the flange and fall out of the workpiece, causing injury
or death.
Setup fingers should only be removed if the mill cannot perform the
necessary machining operations on the workpiece with them still
attached to the chuck feet. Removing the setup fingers reduces stability
of the machine.
In addition to this minimum torque of 325 ft-lb (441 Nm), as many of the follow-
ing securing methods as possible should be used in combination. Vertical and
inverted mounting applications must use either the weld plate or the flange
clamp, in addition to locking the jacking feet. See Section 3.8.3 on page 41 and
Section 3.8.5 on page 43 for more information on vertical and inverted mounting.
• Internal locking nut: An internal locking nut is provided with each
jacking screw, and it should be tightened when the machine is centered
and the jacking screws are torqued to spec. The intent of using the
internal locking nut is to help prevent back-off of the jacking screw due
to machine vibration during operation. See Section 3.5.2 on page 29.
• Weld plate: These four plates must be thoroughly welded onto the
workpiece (with a fillet weld the length of each end and a couple short
fillets across the front) with the machine in place, and bolted onto the
adjustable leveling chuck foot.
• Flange clamp: The flange clamps are provided with the adjustable lev-
eling jacking bolts and are composed by the setup finger and the inter-
nal flange clamp. These elements will clamp onto an interior surface of
the mounting flange.
Do not remove the crane until the jacking screws are tightened to the
specified torque (325 ft-lb [441 Nm]) and at least one of the securing
methods is in place.
3.11 INSTALLING CABLES
Falling or rotating machinery can seriously injure the operator. Make
sure the machine is secured to the workpiece before connecting power
cables.
