The MH3D is supported by a
base that is an aluminum casting of
open web design. This construction
provides a structure that is both
light and stiff.
Three isolation pads with adjustable
screws and nuts are fastened to the
bottom of the base and are used for
leveling the machine. The pads also
prevent vibrations from being
transmitted to the machine and the
workpiece.
Two adjustable bolts are fastened to
the bottom of the base and are set
with 1mm-1.5mm (.040"-.060")
clearance above the top of the bench. These bolts prevent the MH3D from
tipping, if it should be bumped or loaded in an unbalanced condition.
Note: These anti-tip bolts Must Not touch the bench under normal conditions.
Three ball-end screws, fastened in the top of the base, provide a three point
support for the work table. These screws are leveled at the factory and do not
normally require adjustment. These screws should only be adjusted if the work
table is not level with the X and Y axes.
The cable track is mounted to the base and houses the encoder cable and air hoses.
The Y axis cable is in a loop between the rail and the base which reduces
hysteresis.
