Do the following for standard shaft mounting with the KM4000:
1. Use a hoist to set the key mill on the shaft. Because the key mill has sealed
lubrication, it can be mounted in any position.
2. Mount the chain clamp assemblies to the clamp blocks on the side of the
base.
3. Secure the key mill to the shaft by tightening first one chain clamp nut and
then the other chain clamp nut. Torque the clamp nuts to 60 ft-lb (81 Nm).
Under-torquing the chain clamp nuts may allow the machine to slip off
of the workpiece, resulting in death or severe crushing injury.
4. Center the cross slide by aligning the zero mark on the back of the slide
with the zero mark on the back of the base.
5. Level the machine. Place a level on the machined upper surface of the base
to be sure the key mill is level. This is crucial when cutting in-line key-
ways.
Careful centering and leveling of the key mill will ensure that all
keyways will be in line.
6. Adjust the tension of the cross slide gib screws by cranking the cross slide
leadscrew to move the cross slide along the dovetail of the base. When the
slide is centered over a gib screw, tighten that screw until there is notice-
able drag on the slide. Unscrew the setscrew slightly. Repeat until all gib
screws are adjusted.
7. Adjust the tension of the top slide gib screws by cranking the top slide
leadscrew to move the top slide along the dovetail of the cross slide. When
the slide is centered over a gib screw, tighten that screw until there is
noticeable drag on the slide. Unscrew the setscrew slightly. Repeat until all
gib screws are adjusted.
