1st I swapped the 5 HP DC drive control
ram with the drive on the on the turret
chose to swap drives rather than repair. 2nd
clutch slips on the turret head when
raising/lowering the head. We just put it
fastest feed to get where we are going in a
The machine has operated like this for at
years and has never bothered us.
Everything else works as it should i.e.
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.
