Climax LM5200 Operating Manual page 31

What is the maximum length and travel of bed? The length of bed available varies in 2 feet
(609.6 mm) increments. The maximum bed length is based on the maximum ballscrew length
available. A shorter ballscrew can be positioned at multiple points down the length of the bed
but one end of the ballscrew must be at one end of the bed in order to use the electric feed.
The travel available takes into account the width of the saddle and is 12 inches (304.8 mm) less
than the bed length for the LM5200, and is 16 inches (406.4 mm) less than the bed length for
the LM6200. The max bed length and travel based on the ballscrew and in increments of 2 feet
(609.6 mm) is as follows:
LM5200 bed – Max bed length of 96" (2438.4 mm) with 84" (2133.6 mm) travel, longer
lengths may be available at additional cost
LM6200 bed – Max bed length of 264" (6705.6 mm) with 248" (6299.2 mm) travel, longer
lengths up to 384" (9753.6 mm) may be available at additional cost
What is the maximum length of ram? The standard maximum ram lengths of 44 inches
(1117.6 mm) for the LM5200 and 116 inches (2946.4 mm) for the LM6200 are based on
ballscrew length and machining rigidity. Ram travel for both the LM5200 and LM6200 are 10
inches (254 mm) less than the ram length. If different ram lengths are desired this can be
explored through the specials process.
Can I use a gantry ram for conventional linear milling? Yes, though there is a point at which
the distance the ram hangs out will greatly affect the machining performance. For maximum
rigidity the LM5200 can machine to 12" (304.8 mm) from the side of the bed to the center of the
spindle, and the LM6200 can machine to 28" (711.2 mm) from the side of the bed to the center
of the spindle.
What is the maximum metal removal rate and how does this compare to the LM6000?
Metal removable rates of 10 in
the LM5200/6200 and are equal to or greater than what is possible with the LM6000.
Is the width the gantry can be spread a set distance? No, the gantry rails are infinitely
adjustable and can be spread to any width desired up to the max width appropriate for the
length of ram you would like to use.
Is it ok to only drive the ballscrew on one gantry bed while machining near the other
gantry bed? During testing we were able to machine with acceptable rigidity and performance
at the extreme gantry dimensions. Proper alignment, leveling, and setup are very important
when machining to the limits of the gantry rams. Maximum metal removal rates will most likely
not be possible when pushing the machine to its dimensional limits. Positional accuracy will be
greatly reduced as well in the +/- 0.010" (0.25 mm) range.
Can I tap with the milling head? Yes, by adding a floating tap head.
What are the side plates for? These plates lock the outside of the bed sections together to
provide extra rigidity.
Are the bed sections going to shift if the leveling screws are over torqued? Measures
have been taken to prevent shifting of the beds under unusual loads. There are button head
cap screws that overlap onto the mating bed section and prevent shifting from one bed section
to another. These scenarios have been thoroughly tested.
I am afraid that my linear rails may have shifted, is my machine okay? Extensive testing
was done to ensure that the rails will not shift under normal usage or even under significant
abusive loads. If you still have concerns contact Climax Engineering. The benefit of the
sectioned bed is that in the case that the rail is damaged a single bed section can be sent back
for repair or replacement.
