2.1 Intended use
Warning
Danger of injury!
¾Use machine only for the processing and materials that are
described under "Correct use".
The TRUMPF Nibbler N 700-2 is an electric hand tool used for the
following applications:
•Slitting plate-shaped workpieces made of a punchable material
such as steel, aluminum, non-ferrous heavy metals, and
plastic.
•Slitting of tubes and machining of edged sheet profiles and/or
press brake bendings, e.g. for tanks, crash barriers, troughs, etc.
•Nibbling straight or curved exterior and interior cutouts.
•Nibbling along scribed lines or templates.
Note
The nibbling process produces workpieces that are free of
deformations.

3.1 Selecting the die
One of three types of dies can be selected for the machining
process, depending on material thickness, tensile strength and
type of workpiece:
Make sure that the X distance is as small as possible so that the
machine is well clamped and does not rattle.

Penetration depth of the punch
The penetration depth of the punch into the die should be 1 to 3 mm.
1. Rotate the eccentric shaft (1) until the punch (3) has reached
its maximum penetration depth.
2. Open locking mechanism (4).
3. Rotate the die carrier (2) by 360° as often as needed until the
punch penetration depth of 1-3 mm has been achieved. One
rotation (360°) corresponds to a height adjustment of 1.75 mm
4. Close locking mechanism (4).

Continuous operation

14 Operation E528EN_03.DOC
1. Do not move the machine towards the workpiece until full
speed has been reached.
2. Machine the material.
–Machine the desired cutting line.
3. In the event that the cutting track ends in the sheet, pull the
machine (still running) a few millimeters back towards where
the cutting track has already been cut open.
4. Switch off machine.
Note
The cutting result is improved and the service life of the punch
increased if the cutting track is coated with oil before machining the
workpiece.
Material Oil
Steel Punching and nibbling oil, Material No. 103387
Aluminum Wisura oil, Material No. 125874
Recommendation for oil
¾Press and release the On/Off switch (2).
4.2 Changing the cutting direction
In situations where space is limited, the tool can be mounted in
such a way as to have a different cutting direction.
•Mount the tool at an angle turned 90° to the right or to the left
(cutting of profiles).
•Mount the tool at a 180° rotation (nibbling to the rear).
1. Open locking mechanism (8).
2. Turn the die carrier (7) in the desired direction.
3. Close locking mechanism (8).
4. Check the depth of penetration of the punch.

4.3 Nibbling with templates
The following requirements must be met when nibbling with
templates:
•The template must be at least 5 mm thick.
•The contour of the template must have a clearance of 11 mm
to the contour to be nibbled out.
•Guide the nibbler in such a way that the exterior cut-out of the
punch guide (5) always remains up against the template.
•Observe a minimum radius of 135 mm.
4.4 Making inner cutouts
Inner cutouts require a start hole of at least 60 mm in diameter.

5. Maintenance
Caution
Damage to property due to blunt tools!
Machine overload
¾Check the tool hourly for wear. Sharp tools cut better and
help keep the machine in good condition. Change the tools as
soon as necessary.
Warning
Danger of injury due to improper repairs!
Machine does not work properly.
¾Repair work may only be carried out by a qualified specialist.

5.1 Changing the tool
If the punch and/or die is blunt or the type of application changes,
the tools must be reground or replaced.
Replacing the punch
1. Release the lock (1).
2. Rotate the die carrier (3) by 45°.
3. Pull die carrier (3) out towards the bottom.
4 Remove punch (2) by rotating it.
5. Lubricate the square part of the punch and die carrier bore
hole with "G1" grease, TRUMPF Material No. 139440.
6. Align the punch to 45°.
7. Check the depth of penetration of the punch.
Changing the die and the punch guide
1. To replace the die and the punch guide, unscrew the fixing
screws (6).
2. Clean the support areas on the die carrier (3).
3. Take care to ensure that the replacement parts are clean.
4. Lubricate the guide surfaces of the punch guide with "G1"
grease, TRUMPF Material No. 139440.
5. Screw the fastening screws tightly when mounting the die and

E528EN_03.DOC Maintenance 19
5.2 Resharpening tools
Punch
The punch can be reground by a total of approximately 10 mm.
•Regrind the grinding surface in accordance with the following
diagram, making sure that it is well-cooled during the process.
•Lightly apply fine-grained oil stone to the cutting edge.
•Observe a minimum length of 89 mm Shorter punches must be
replaced (risk of collision).
Dies
Dies may not be reground.

5.3 Checking/replacing the wearing plate
1 Elevation 2 Depression
Wearing plate
The wearing plate protects the die carrier against excessive
wearing. (Order No. 0119173V.)
1. Replace the wearing plate when the raised part (1) is worn
down.
2. Replace the wearing plate when the depression (2) is no
longer visible.
Note
Excessive wearing can overload the machine and lead to a
worsening of cutting quality.
5.4 Replacing carbon brushes
The motor comes to a standstill whenever the carbon brushes are
worn out.
¾Have the carbon brushes checked and replaced as required by
a qualified specialist.
Note
Only use original replacement parts and observe the specifications
on the type plate.
