Page 36 KM3000 KM4000 Operating Manual
Always make a visual inspection of the entire machine paying particular attention
to cables, hoses and their connectors, that they are clean and functional. Repair or
replace any parts that show signs or wear or damage.
Mount the machine as described in Section 3.4 on page 23.
With the power source disconnected, move the machine around its entire travel
range to ensure that it is free of obstacles.
When the mill is set at an extreme angle, metal chips created from
machining the workpiece can foul the leadscrew.
4.3.1 KM3000/KM4000 electric machines
Do the following:
1. With the end mill properly mounted on the shaft, set the speed control to
the desired spindle rpm.
2. Lower the end mill to cut a flat on the shaft equal to the diameter of the end
mill.
3. Set the depth dial to zero. The dial is calibrated to move the spindle and end
mill 0.100" (2.5 mm) per revolution.
4. Plunge the end mill by cranking the vertical adjustment clockwise until the
end mill is at the required depth.
5. Operate the traverse drive to cut the full length of the keyway.
6. After the keyway has been cut, raise the end mill clear of the work piece.
4.3.2 KM3000/KM4000 pneumatic machine
Securely mount the key mill to the work piece before connecting the air
supply.
The air filter and lubricator supplied with the machine must be used or the machine
warranty is void. Set the lubricator to deliver oil at a rate of 20–30 drops per min-
ute at full throttle.
Using air that is not filtered or lubricated can damage the air motor.
Avoid damage by routing incoming air through the filter and lubricator.
The air line should be at least 0.5" (13 mm) in diameter.
