Two range simple
transmission
12,000 lbs table load
Automatic lubrication
Constant surface cutting
Power indexing turret
head
75 Hp DC table drive
All heads are DC drive
Rail head AC drive with
self leveling
feature
and automatic locking
There is a box full of
gears I suspect
are for
thread cutting and drum
scoring
1st I swapped the 5 HP
DC
drive control
for the
ram with the drive on the
on
the turret
head. I
chose to swap drives rather
than repair. 2nd
the
clutch slips on the turret
head when
raising/lowering the head.
We just put it
into the
fastest feed to get where
we
are going in a
hurry.
The machine has operated
like this for at
least 8
years and has never
bothered
us.
Everything else works as
it should i.e.
table,
rail, lube pump, way lube
feeders etc
I believe the machine was
made to be floor
mounted and we installed it in
a pit to lower
the overall height of the
machine for (1) hoist
rail bridge clearance and (2)
to keep the table
height lower. Currently our
hoist rail will not
clear the operator station
counterweighted
davit arm on top of the
machine
but it really
does not need to as we only
lift machining
parts – not the Gray’s parts.
The pit depth is
20.5” and the table height to
the floor is
17.5”. If floor mounted it
would put the table
at 38”. Not a bad working
height. The 75 HP DC
motor is mounted on the
working
floor and is
belt driven to the table drive
sheave in the
pit. The DC motor is on a
separate frame so I
would think it may just be a
matter of some
shorter belts if both machine
and motor were on
top of the floor.
