Intended Use

NE-CUT is specially designed to cut FR4 PCB boards up to 3.0 mm or aluminium up to 2 mm thickness.

epending on customer application cutting of steel (depending on the alloy up 0.8 mm) and plastic (up to

5 mm) is also possible same as paper or film material. The board cutter is preset for board thickness up to

3.0 mm. If you need to cut thicker material you need to adjust the upper blade and the clamping unit.

All other applications require our written consent, or happen at your own risk and peril.

Safety Regulations

enerally

Please read the following text carefully and pay particular attention to information on safety and commis -

sioning.

Keep this folder at a safe place. It contains information which is also for later maintenance and cleaning of

importance.

The machines are not designed to be embedded or interconnection with other machines or systems. They

may only be used in specially equipped rooms and be operated by qualified personnel. Keep away chil -

dren and pets!

Transport

Only use suitable lifting and transport equipment such as forklifts or pallet trucks . Secure the machine

against sliding / tilting

Operation site

The site should be level, site- and slip-resistant. Unrestricted access to the rear of the machine is required

for the installation of add-on parts ; later on it enables you to easily remove the cuttings .

Operating

All dangerous parts are covered as far as technically possible and reasonable. The gap between

table and clamping device is only 5 mm, so it is almost impossible to get your hand into the blade

while the clamping device is mounted.

The only source of danger is behind the machine. Never pull the lever while you or anybody else is

working behind the machine. Especially when somebody is trying to remove the cut boards from be-

hind the machine.

Always were cut proof gloves when handling the blades. Secure the loose blades from being touched

or from falling down.

For very small sections, it may happen that they stick under the knife. Caution, risk of injury! Lower the up-

per knife till the cutting gap is closed before putting your hands into the cutting area.

Set Up

Take over from the transport agent

After receiving and unpacking check the machine for possible transport damages. In case of transport

damage, please inform your insurance, the transport company and the manufacturer / supplier.

Transport to operation site

Only use suitable lifting and transport equipment such as fork-

lifts or pallet trucks . Secure the machine against sliding / tilting

First take out the filling material and then the disassembled

parts. Bring the latter to the place where you want to operate

the machine.

Remove the transport screws (picture 2)!!

Because of its heavy weight carry the Ne-Cut only with two per-

sons. Hold on one hand to the table and the other under the

ground plate.

For transport reasons some parts of the Ne-Cut are disas-

sembled:

1. back stop with metric scale

2. the lever

Operation Site

The Operation place should be solid, even and not slippery. 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 you to remove the cut boards easily.

Make sure to have enough light in the room. If necessary install a

separate light source next to the machine in order to have a clear

sight over the cutting area.

Mounting

Mount now the add-on-parts. All you need is a set of Allen keys and

a set of jaw wrenches.

1. Lever (picture 3): Stick the lever into the opening on the

right side of the eccentric axis, the chamfer pointing to the

right. Tighten the lever with the headless Allen key screw.

2. back stop with metric scale (picture 4): When you look

from the rear to the upper blade beam you see two

loosely mounted Allen key screws. Unscrew them and ad-

just here horizontally the flange of the slide beam. Tighten

the screws hand tight.

Set the counter-bar to a deliberate position. Loosen the

red lever (you can change position of the knob by lifting

and turning).

Turn the lever up and back to its home position. Take a wide board and scoop it first against the front side

counter bar and then against the rear counter bare.

Pull the lever until the clamping unit fixes the board. In this position you can adjust the height of the rear

counter bar until it lies smooth against the board. Now tighten the Allen key screws.

The parallelity of the rear counter bare was pre-adjusted and proved before the machine left the company.

However it happens sometimes that the rear counter bare does not fit after disassembly. The reason for

this could be a an unevenness of the finishing coat. If you happen to notice a disparallelity after some test

cuts, please read chapter adjustment how to scale the counter bare again.

Operating

Adjust the size of the board to be cut with the rear counter bare: Loosen the orange knob by 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 precisely by knocking against the skid of the counter bare. Then tight the knob

firmly. 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 (clamping unit) will clamp the board and then the

blade will cut it. Pull the lever all the way back, so the clamping unit releases the board.

If you place the board precisely to the scale of the front counter bare, you can even perform some cuts

without adjusting the rear counter bare. Or you can trim the rims of the board by sight. If you work without

the rear counter bare, it can happen that the board is pushed back by the blade for about 0,1-0,2 mm.

That is a general side effect of the cutting 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 regularly the cuts and the oddments from the ground plate of the machine. If

the oddments are very small, they might stick underneath the blade. Attention: risk of injury! Lower the

upper blade until the gap between upper and lower blade is closed before you remove these small parts.

Disassem ly

ismount the rear counter bar only for transport reason, because

you have to go through the adjustment procedure again after you

mount the counter bare . This procedure 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 safety reasons always keep the clamping unit in its position.

Nevertheless you can remove the clamping unit by pressing it down

on the side till it comes free from the press beams which connect the

clamping unit with the lowering mechanism.

Turn away the press beams and lift the clamping unit.

If you need to have access to the lower blade you must remove the

machine table. Loosen the two screws which connect the table to the

ground plate (Picture 5). After remounting the table you have to con-

trol the perpendicularity of the table and if needed, readjust the scale

of the front counter bare (see chapter adjustment).

After you removed clamping unit and table you see a square pipe

which holds the lower blade (Picture 6). You can reach the attach-

ment screws through the big top holes. Loosen the screws and take

out the square pipe with the lower blade. If you unfasten the screw

coupling you can remove the lower blade.

In order to remove the upper blade just loosen the screws of the up-

per blade beam.

Please pay 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 they were before. After remounting the

blades you need to readjust the gap between the two blades (see

chapter Adjustment).

Attention, danger of injury! Always were cut proof gloves when hand-

ling the blades. Secure the loose blades from being touched or from falling down.

Under normal conditions it is not necessary to dismount the upper blade beam, the eccentric axis or other

parts. Nevertheless if you must do so for repair reasons for example please get in touch with us.

Adjustment

Upper Blade

The upper blade is connected with screws to the blade beam. The only possible

adjustment 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 pre-ad-

just the angle this way and you 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 (distortion).

Change the angle by first loosening the counter nut and then turn the

hexagon bolt between eccentric axis and blade holder (Picture 7).

Lower Blade

To disassemble the table and lower blade read chapter Dis-

assembly. The lower blade is closely connected to its hold-

er. To change the gap between upper and lower blade you

can move the holder of the lower blade along the ground

plate.

To do so use the 5 headless screws which you find between

the steel bracket welded to the ground plate and the holder

(Picture 8). First mount the upper blade and lower it down

as far as possible.

For the now coming adjustment you need a distance tem-

plate. 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 thickness. For pcb sheets you

can reduce the gap.

Tighten the attachment screws of the holder just slightly and move the holder with the lower blade

evenly against the template that lies before the upper blade. Tighten the attachment screws hand

firm. Now loosen the counter nuts of the headless screws and turn these screws till they touch the

holder.

Take the template out of the cutting gap.

Now cut small stripes of the thinnest material you 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 only bend, turn in the nearest

headless screw for some degrees and repeat the cut.

Repeat this action until your sheet was nicely cut all along the blade.

o not turn the headless screws too far, thus you may damage the blades. If the

screws happen to be too far in, you have to loosen all screws and start the procedure

once again. When you are done do not forget to tighten the attachment screws!

Front Scale

This adjustment is always necessary when the table was disassembled

(change of blades). To assure a perpendicular cut walk through the fol-

lowing steps:

Check if the screws between table and ground plate are tightened. Pull

the machine over the edge of the table until you can reach the front

most attachment screw of the ruler. Loosen this screw carefully (see

picture 9). 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 you notice that the scale of the ruler does not fit anymore you

will have to move the table itself. Or you can loose the other attachment

screw of the ruler as well and move the ruler.

Rear Back Stop

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 parallelity 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.

To adjust the angle of the counter bare take an Allen key and

turn the headless Allen key screws on the left and on the

right of the counter bare (see picture 3).

On the side where you turn out the headless screw, the size

of the cut will become smaller. On the side where you turn in the screw the gap accordingly will become

igger. Normally you will have to do a couple of test cuts till both sides are exactly 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.

Cleaning and Maintenance

After use clean the machine from dust and chips by vacuuming especially the blades and behind the

blades. o not use compressed 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 regularly all moveable parts, especially slides of the upper blade run and the rings

around the eccentric axis. epending on the amount of cuts and the material to be cut, the blades need to

be exchanged or resharpened. We offer blades as spare part so you can keep a blade-set in reserve.

Disposal

The board cutter Ne-Cut is made from recyclable materials and is to be supplied at a later decomissioning

in a proper and environmentally friendly manner.
