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.

3.3 Checking penetration depth

of the punch

1 Eccentric shaft

2 Die carrier

3 Punch

4 Locking mechanism

E Penetration depth

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).

3.4 Selecting the handles

Suitable handles can be used depending on the exact application.

2 handle types are available:

•Bow-handle.

•Compact handle.

1 Clamping lever

¾Fasten the handle to the machine without a tool using the

clamping lever (1).

Indexing means that each handle can be clamped in 2 positions.

1. Turn the clamping lever (1) by approx. 2 revolutions.

2. Swivel the handle.

3. Fix the clamping lever (1).
