VESSEL Air Nippers
for all your needs (5)VESSEL has solved users' problems.
Here are some examples of our solutions.

Problem #1

Cutting edges are bent due tolack of strength.

Workpiece: Copper wire
Blade that was used: Blade for metal (carbide tipped)

Our Solutions
Custom-made thin tip blade
Nipper: GT-NＷS20
Custom-made blade: NＷ20BJ[***]

Causes: Since the blade tip
had to be thin for insert into
the equipment, the standard
blade was grinded by the user
to make it thinner. As a result,strength of the blade tip was
reduced, which caused its
bending and misalignment of
the cutting edges.

Problem #2

Need to retain the copper wire
after cutting.

Workpiece: Copper wire2.8~4.5Φ
Blade that was used: Commercially available robotic hand air chuck

We have designed a blade to meet thecustomer's requirements by asking
about speciﬁcations of the workpieceand restrictions around theequipment.
Some standard blades can beadditionally machined to be thinner,
but in this case it is necessary to
beware the blade tip strength.

Our Solutions
Custom-made wire retaining blade
Nipper: GT-NS20Custom-made blade: N20DI[***]

Causes: A non-slip chuck jaws
will scratch the enameledcoating of the copper wire
when they grip it. With astraight chuck, the copper
wire will be displaced andscratched.

Problem #3

When cutting brass material,
there is a cutting residue.

Workpiece: Brass hoop material (4×0.6mm)
Blade that was used: Blade for metal

Causes: Used to use thecarbide tipped blade and theNS30 nipper. The nipping
blade sometimes did not cut
fully the material, leavingsome that was not cut,because it is soft and thinrather than because of thecapability of the nipper itself.

Quotation is free.

We designed a special retaining bladewith an " hollow" that matches the wirediameter.
Multiple shapes were designed
according to various sizes of the wire.
The place where the wire comes incontact is chamfered, and the retaining
force is adjusted by a decompression
valve so as not to crush the wire.

Our Solutions

Custom-made scissor bladewith carbide chip

Custom-made nipper: GT-NS20
Blade: N20VHAB[***]

Scissors-shaped blade is custom-madeto meet the application so as to cut thematerial while the cutting edges slide
perfectly, and to prevent the wirematerial from remaining between thecutting edges. The model selection for
nippers was reviewed, which reduced
the weight of the whole equipment.

Trial cutting of your workpiece on request.

If you cannot ﬁnd a suitable blade for your work among the standard blades, we will design and manufacture a blade to your speciﬁcations.
We will provide you with approval drawings and pricing after discussing model selection and blade design.

Problem #4

Our Solutions

When cutting a copper wire,
there is a cutting residue.

Workpiece: Copper wire
Blade that was used: Blade for metal (carbide tipped)

Custom-made scissor bladewith carbide chip

Nipper: GT-NR50
Custom-made blade: N50**[***]

Causes: As the blade wears down,
more gap between the cuttingedges is made, leaving the residue
from the cutting. Durability isimproved with the carbide chipthat is brazed, but the increase in
the cost due to frequency ofreplacement of the whole blade
because of wear is also an issue.

Problem #5

To cut a thick copper wire, thenipper must have the N50 typecapability. Considering durabilityof the blade and ease ofmaintenance, the carbide chip of
the same shape is adopted on theupper and lower side of the blade
respectively, which allows easy
replacement of the chips.

Our Solutions

Custom-made bladewith reinforced springThin wire is stuckand equipment stops.

Nipper: GT-NS30
Custom-made blade: N30VHAB****

Workpiece: Thin copper wire, Thin copper sheet
Blade that was used: N30VHAB****
Causes: The soft copper wire
may be stuck in the blade when
it is worn or inserted to thewrong position. When theequipment stops because ofthese, the entire line comes to ahalt and the production isdisrupted.

←Reinforced spring←2-spring type

Problem #6

Equipment does not have enoughspace to have a nipper in it.
Workpiece: Copper wire
Blade that was used: N3BJ

Causes: Since this isfor application to cut
thin wires, a small
nipper is chosen, but
actually it cannot be
installed becauseeven such a small
type interrupts theequipment.

The piston inside the nipper
makes the cutting edges close,
and the blade spring opens them.
If some copper wire that was
uncut gets caught in the gap
between the cutting edges, theblade will not work. In this case,use a reinforced spring to open
the blade by force.

Our Solutions
Custom-made side opening blade
Nipper: GT-NS3
Blade: N3BM****
By using the side opening blade,the nipper can now be placed on
the equipment without problems.
If there is a space for theGT-NF05, the standard model cansupport, and further cost
reduction can be expected.
