Shortening of Work Piece on a Circular Saw before notching
Before the notching of the work piece it must be cut to the correct length on a circular saw.
It is very important that the saw blade is exactly adjusted to 90°to the machine table
(see B-1). The blade must also be exactly adjusted to 90°to the fence (see B-2).
Discrepancies arising from these cuts will result in gaps in the finished joints.

General Descript
i
on
MORSØ-NXLEH guillotine is the optimum machine to cut window bars, mullions, and cabinet
front frames requiring haunch joints.
MORSØ-NXLEH is a fully automatic, electric/hydraulic machine. The operation is easy.
Activating two push button switches starts the cutting.
MORSØ-NXLEH guillotine is provided with 6 flip stops, fences (1500 mm) on both the right
and left side of the machine, nose knives, side knives, chip-breaker, cock-bead stops, centre
stop, safety guard, and waste chute.
With the MORSØ-NXLEH you are always sure to achieve an extremely smooth, clean, and
exact cut by cutting the work piece in two cuts.
This is done automatically on the MORSØ-NXLEH due to the sensors in the cock-bead
stops.
These stops simultaneously function as a working cycle, because the knife block
automatically goes to the last position to complete the cutting after which it returns to stop
position.
MORSØ-NXLEH therefore works continuously without the horizontal position of the knife
block having to be adjusted manually.
The height movement of the knife block (length of stroke) is adjustable in two positions.

Machine Description
PICTURE C-2:
The MORSØ-NXLEH is constructed as a compact machine with a solid dimensioned frame
(1), with built in hydraulic system (2) and electric equipment (3).
The cutting assembly (4) is placed on top of the machine.
In the slide frame (5) fitted at the cross (6) the knife block (7) is moved up and down. The
cross (6) runs in the guidings of the table.
The knives (8) fitted on the knife block cut not only the notch, but also cope the corners to
complete the joint.
Hydraulic cylinders draw the conveying and the knife block.
PICTURE C-2-1:
The stile is placed on the table (9) against the fixed fences (10). The setting of the moveable
fence (11) to the width of the stile is made by pushing this fence (11) towards the fixed fences
(10) until there is a distance of about 5 mm between the stile and the moveable fence (11)
PICTURE C-2:
The cock-bead stops (12) are adjusted to the required cutting depth. The clamping cylinders
(13) are adjusted to the width of the work piece.
The clamping cylinders are fitted direct on the table.
The adjustment of the flip stops (14) is done by means of a template of the work piece.
The waste is falling via a slide (cover of the hydraulic system) on the floor or in a waste
receiver.
MORSØ-NXLEH can be fitted with nose knives from 12 to 26 mm (1/2” – 1 1/8”).
MORSØ-NXSEH can be fitted with nose knives from 6 to 20 mm (1/4” – 3/4”).

Description of the Hydraulic System
All automatic movements are carried out by means of the hydraulic system.
All the functions of the hydraulic system are adjusted from the factory. This must not be
changed as it can lead to disturbances in the process.
After starting the machine, wait about 1 second before the cutting is started. During this
period the oil pressure for the process is built up.
The hydraulic pump (2) driven by an electric motor (1) gives the hydraulic pressure
necessary to be used in the hydraulic cylinders (3), (4) + (5) for the conveying and the
movements of the knife block and clamping cylinders.
The hydraulic pump (2) draws the oil through a suction filter out of the tank (7) and to the
valves. After the pulse release the electronic control regulates the opening and the closing,
respectively, of the valves (8) so that the controlled cylinders are provided with oil.
Please note: If the hydraulic pump breaks, it cannot be repaired, but must be replaced
by a new pump.
The oil that is not used for the process goes back to the tank through the return filter (9).
WARNING
The built in hydraulic system must not be covered up and must be kept free of waste as
these things can cause extreme heating resulting in the worst damages.
