The
NFX series was developed in response to American furniture and
cabinet designs requiring wider moulding profiles (for crown
moulding on top and toe-kick on bottom of cabinets).
The machine features
a heavy-duty steel frame with cast iron tabletop. The vertical
travel of the cutting head, which is also made of cast-iron, can
be adjusted depending on workpiece thickness, assuring
comfortable and efficient operation.
The machine is
equipped with two cast-iron table extension leaves, which are
bolted to the main table. Steel pins provide accurate alignment.
Mounted on top of the table extension leaves are anodized
aluminum fence rails, which offer material support and are used
in conjunction with flip-stops to position multiple cuts along a
stile or rail. These fence rails are also bolted and pinned to
the table leaves.
A center stop assembly in the middle of the
machine table is used to position the rails for cope cuts. The
solid aluminum center stop bar slides in and out and is locked
in place with a thumbscrew. Interchangeable nylon center
fittings with fine adjustment screws are installed in the center
stop bar and are available in different widths, depending on the
nose knife used.
A nylon chip breaker is installed in the machine
table. The chip breaker protects the cutting edges of the knives
and also prevents any tear-out on the back of the workpiece.
Heavy aluminum blocks with two setscrews act as
“cock-bead" stops. These blocks are mounted on steel guide rails
next to the side knives. Once set, the stops limit the forward
travel of the cutting head and assure accurate notching depths.
Because the stops use the beaded edge of the moulding as
reference point, this design completely avoids to problems
associated with systems using the opposite moulding edge
instead.
Center Fence Details
The main difference
between the NFX and the NF series is the moveable center fence
assembly on the NFX.
Two 5-foot long fence rails are mounted along the back edge of
the table extensions (along the front edge on the NF). The
center fence assembly can be moved in and out, allowing moulding
up to 8” in width to be placed between the center fence and the
nose knife.
The center stop,
which is fastened to the machine table on the NF models, is also
part of the moveable center fence assembly on the NFX.
Four additional
grooves are machined into the cast iron table, the angled outer
grooves holding locking fittings to lock the fence assembly into
place. The straight grooves in the center contain moving steel
channels, which guide the center assembly to assure parallel
alignment to the nose knife and extension fences.
Nose
Knives
The nose knives feature a machined v-groove in
the back to guarantee accurate alignment on the cutting head. In
addition, two counter sunk hex-head screws are used to mount the
nose knives to the tip of the cutting head.
The side knives are bolted to the head with
heavy-duty machine bolts. Slots in the knives allow for lateral
adjustment depending on the width of the nose knife. The side
knives are designed to be compatible with both the small and
large cutting heads for the NF and NEH machines.
All MORSO knives are manufactured with
custom-made Austrian steel and are hardened to Rockwell 64. No
other manufacturer of miter cutting and notching equipment
offers knives harder than Rockwell 58!
Notching
Operation
Upon adjusting the cock-bead stops to set the
notching depth, the moulding is placed on the machine table and
one end is rested against a flip-stop. The hand lever in front
is used to move the cutting head horizontally to and from the
operator. Depending on the width of the cut, the thickness and
hardness of the moulding, two to four cuts are made to complete
the notch. This process takes only seconds and the resulting
cuts are smooth and free of tear-out.
Coping Operation
Upon adjusting the setscrews in the nylon center
fitting, the stop is moved toward the cutting head and locked in
place. The rail is placed on the table and pushed against the
stop. The 45-degree corner cut on the bead is made in one cycle,
multiple cuts are not necessary. The moulding is then flipped
end-for-end and the process is repeated.
