Application

NE-CUT is suitable for boards up to a width

of 530 mm. The maximum thickness of the

board depends on the material ou want to

cut. You can cut FR4 up to 3 mm, aluminium

depending on the allo up to 2 mm and

sheet steel depending on the allo up to 1.0

mm.

The cut has to be done in one stroke b a

normal strong man. A mechanical or electric-

al aid like a lever or a motor is not allowed.

This might damage the board cutter irrepar-

able.

The thinnest material ou can cut is 0,1 mm

(new board cutter or just sharpened blades

assumed). This enables the cutter even to

cut film material, clichés etc..

Features:

•Cutting width max. 530 mm

•Two knifes made of hardened and

ground steel

•Spring loaded built-in clamping unit in

the front

•Transparent cover hood for user safet

and visual control

•Metric edge scales in the front

•Full adjustable back stop with metric

scale for batch work (0...300 mm)

Security

All dangerous parts are covered as far as

technicall possible and reasonable. The

gap between table and downholder is onl 5

mm, so it is almost impossible to get our

hand into the blade while the downholder is

mounted.

The onl source of danger is behind the ma-

chine. Never pull the lever while ou or an -

bod else is working behind the machine.

Especiall when somebod is tr ing to re-

move the cut boards from behind the ma-

chine.

Alwa s were cut proof gloves when handling

the blades. Secure the loose blades from

being touched or from falling down.

Set Up

Important: Receiving the machine please im-

mediatel check for an transport damage. If

ou notice an transport damage please in-

form us and the carrier.

For transport reasons some parts of the Ne-

Cut are disassembled: the rear counter bar,

the belonging slide beam with scale, the

lever and the hood.

First take out the filling material and then the

disassembled parts. Bring the latter to the

place where ou want to operate the ma-

chine.

Remove the transport screws!!

Because of its heav weight carr the Ne-

Cut onl with two persons. Hold on one hand

to the table and the other under the ground

plate. The Operation place should be solid,

even and not slipper . The room should

have a non-corrosive atmosphere. A good

access to the rear is important to assemble

the counter bar and later on it will enable

ou to remove the cut boards easil .

Make sure to have enough light in the room.

If necessar install a separate light source

next to the machine in order to have a clear

sight over the cutting area.

Mount now the add-on-parts. All ou need is

a set of Allen ke s and a set of jaw

wrenches.

Stick the lever into the opening on the right

side of the eccentric axis, the chamfer point-

ing to the right. Tighten the lever with the

headless Allen ke screw (see picture1).

When ou look from the rear to the upper

blade beam ou see two loosel mounted Al-

len ke screws (see picture 2).

Unscrew them and adjust here horizontall

the flange of the slide beam. Tighten the

screws hand tight.

Set the counter-bar to a deliberate position.

Turn the lever up and back to its home posi-

tion. Take a wide board and scoop it first

against the front counter bar and then

against the rear counter bare.

Pull the lever until the downholder fixes the

board. In this position ou can adjust the

height of the rear counter bar until it lies

smooth against the board. Now tighten the

Allen ke screws.

The parallelit of the rear counter bare was

preadjusted and proved before the machine

left the compan . However it happens some-

times that the rear counter bare does not fit

after disassembl . The reason for this could

be a an unevenness of the finishing coat. If

ou happen to notice a disparallelit after

some test cuts please read chapter adjust-

ment how to scale the counter bare again.

At last mount the hood and tighten it with

four screws. The two notches of the hood

belong to the rear side.

Operation

Adjust the size of the board to be cut with

the rear counter bare: Loosen the orange

knob b lifting and turning. Slide the counter

bare to the rough dimension of the board,

tighten the knob a little bit and adjust the

zero position mark precisel b knocking

against the skid of the counter bare. Then

tight the knob firml . Place the board against

the front counter bare and push it against

the rear counter bare.

Pull the lever to the front and down. The

downholder will clamp the board and then

the blade will cut it. Pull the lever all the wa

back, so the downholder releases the board.

If ou place the board precisel to the scale

of the front counter bare, ou can even per-

form some cuts without adjusting the rear

counter bare. Or ou can trim the rims of the

board b sight. If ou work without the rear

counter bare, it can happen that the board is

pushed back b the blade for about 0,1-0,2

mm. That is a general side effect of the cut-

ting procedure and no defect of the machine.

To reduce this effect we offer as an option a

front parallel counter bare.

Please make sure to take out regularl the

cuts and the oddments from the ground

plate of the machine. If the oddments are

ver small, the might stick underneath the

blade. Attention: risk of injur ! Lower the up-

per blade until the gap between upper and

lower blade is closed before ou remove

these small parts.

Disassembly

Dismount the rear counter bare onl for

transport reason because ou have to go

through the adjustment procedure again

after ou mount the counter bare . This pro-

cedure is described in the chapters Set Up

and Adjustment. The counter bare itself can

be slid off the beam after the knob is loose.

For safet reasons alwa s keep the down-

holder in its position. Nevertheless ou can

remove the downholder b pressing it down

on the side till it comes free from the press

beams which connect the downholder with

the lowering mechanism.

Turn awa the press beams and lift the

downholder. If ou need to have access to

the lower blade ou must remove the table.

Loosen the two screws which connect the

table to the ground plate.

After remounting the table ouhave to con-

trol the perpendicularit of the table and if

needed readjust the scale of the front

counter bare (view chapter adjustment).

After ou removed downholder and table ou

see a square pipe which holds the lower

blade. You can reach the attachment screws

through the big top holes. Loosen the

screws and take out the square pipe with the

lower blade. If ou untight the screw coup-

ling ou can remove the lower blade.

In order to remove the upper blade just

loosen the screws of the upper blade beam.

Please pa attention to the alignment of the

blades: do not change the angles of the

blades when regrinding them and remount

the blades into the same position the were

before. After remounting the blades ou

need to readjust the gap between the two

blades (see chapter Adjustment).

Attention, danger of injur ! Alwa s were cut

proof gloves when handling the blades. Se-

cure the loose blades from being touched or

from falling down.

Under normal conditions it is not necessar

to dismount the upper blade beam, the ec-

centric axis or other parts. Nevertheless if

ou must do so for repair reasons for ex-

ample please get in touch with us.

Adjustment

Rear Counter Bare

After assembling the slide beam of the

counter bare, take a preferable broad piece

of board, push it against the rear counter

bare and cut it. Prove the parallelit of this

cut with a precise caliper gauge on the left

and on the right. If the cut is not parallel, do

the following:

Take a jaw wrench and loosen the backmost

of the two nuts underneath the counter bare.

(3)

To adjust the angle of the counter bare take

an Allen ke and turn the headless Allen ke

screws on the left and on the right of the

counter bare (see picture 3).

On the side where ou turn out the headless

screw, the size of the cut will become smal-

ler. On the side where ou turn in the screw

the gap accordingl will become bigger.

Normall ou will have to do a couple of test

cuts till both sides are exactl equal.

At last tighten the nut from underneath the

counter bare again and measure the size of

the cut. Check if the zero position mark fits

to the size of the cut. If not, loosen the

screws of the metal plate and shift the zero

position to its proper place.

Upper Blade

The upper blade is connected with screws to

the blade beam. The onl possible adjust-

ment is the angle from left to right. This

angles influences the power of the cut. The

cutting goes easier when the angle is as

aslope as possible. We preadjust the angle

this wa and ou should avoid to change this

since it influences the maximum thickness

and width of the board to be cut as well as

the shear forces attacking the boards (dis-

tortion).

Change the angle b first loosening the

counter nut and then turn the hexagon bolt

between eccentric axis and blade holder.

Lower Blade

To disassemble the table and lower blade

read chapter Disassembl . The lower blade

is closel connected to its holder. To change

the gap between upper and lower blade ou

can move the holder of the lower blade

along the ground plate.

To do so use the 5 headless screws which

ou find between the steel bracket welded to

the ground plate and the holder. First mount

the upper blade and lower it down as far as

possible.

For the now coming adjustment ou need a

distance template. You can take foil with a

defined thickness of 0.1 mm or take two

sheets of normal paper. You calculate for

metals a gap of 1/10 of the materials thick-

ness. For pcb sheets ou can reduce the

gap.

(4)

Tighten the attachment screws of the holder

just slightl and move the holder with the

lower blade evenl against the template that

lies before the upper blade. Tighten the at-

tachment screws hand firm. Now loosen the

counter nuts of the headless screws and

turn these screws till the touch the holder

(see picture 4).

Take the template out of the cutting gap.

Now cut small stripes of the thinnest material

ou want to cut (film material e.g.) all along

the blade from the left to the right. At places

where the material was not cut but onl

bend, turn in the nearest headless screw for

some degrees and repeat the cut.

Repeat this action until our sheet was

nicel cut all along the blade. Do not turn the

headless screws too far, thus ou ma dam-

age the blades. If the screws happen to be

too far in, ou have to loosen all screws and

start the procedure once again. When ou

are done do not forget to tighten the attach-

ment screws.

Front S ale

This adjustment is alwa s necessar when

the table was disassembled (change of

blades). To assure a perpendicular cut walk

through the following steps:

Check if the screws between table and

ground plate are tightened.

(5)

Pull the ma-

chine over the

edge of the

table until ou

can reach the

frontmost at-

tachment screw

of the

ruler. Loosen

this screw care-

full (see pic-

ture 5). Take a

perpendicular

test board,

push it against

the upper blade and knock with a small

plastic hammer against the ruler till the hole

side of the ruler touches the board.

Tighten the attachment screw and make a

test cut. Check the angle again. If ou notice

that the scale of the ruler does not fit an -

more ou will have to move the table itself.

Or ou can loose the other attachment

screw of the ruler as well and move the

ruler.

Maintenance

After use clean the machine from dust and

swarfs b vacuuming especiall the blades

and behind the blades. Do not use com-

pressed air to clean the machine from FR4

dust because then the fibre glass fibres are

dispensed all over the room.

You can clean the hood with a smooth cloth

and some non abrasive cleaner.

Clean and grease regularl all moveable

parts, especiall slides of the upper blade

run and the rings around the eccentric axis.

Depending on the amount of cuts and the

material to be cut, the blades need to be ex-

changed or resharpened. We offer blades as

spare part so ou can keep a blade-set in

reserve.
