The Advantage
of the FASSCO paper
knife...
FASSCO F-3000 18% tungsten
inlaid high speed steel is the world's best made and longest lasting high speed
paper trimming knife on the market today.
The advantages of the FASSCO F-3000 paper
knife:
 Confidence that only the best suited
materials will be used. All F-3000 high speed steel knives are made from a T1
inlay containing 18% tungsten. Expect 3-5 times longer life than standard
knives.
FASSCO F-3000 knife is the only knife
that is heat treated in a thermostatically controlled vacuum furnace. This
expensive method of heat treating ensures that the cutting edge has a uniform
hardness. The results are cleaner, longer lasting cuts between regrind. This
optimal heat treatment also makes the FASSCO F-3000 the easiest high speed
steel knife to resharpen and hone.
All FASSCO
F-3000 high speed steel knives are made per OEM specifications, including the
angle. Most of our competitors standardize all angles at 24°. However, most
European machine builders specify a 22° angle.
We guarantee our FASSCO F-3000 paper trimming
knives to outperform any high speed knife on the market
today.
Compare one FASSCO F-3000
knife to your present brand for:
Length of service between regrinds.
Straightness and
fit.
Accuracy of bevel.
Sharpness and keen edge. |

Schönenberger
tungsten carbide knives last
longer!
Constantly increasing
demands for improved productivity require extensive use of the most
wear-resistant materials available. Schönenberger tungsten carbide is the
ideal material for many applications due to its high hardness, high compressive
strength, resistance to high temperatures, dramatic wear-resistance and
excellent toughness. These and many other useful properties are the results of
the metallurgical structure of this composite material. Cobalt binders for
toughness and nickel alloy binders for corrosion resistance are the matrix for
the wear-resistant grains of tungsten carbide and its alloys. By varying the
binder content and size of tungsten carbide grains, we can achieve a wide range
of qualities for different applications.
The benefits of tungsten
carbide are many. Schönenberger tungsten carbide knives will perform 10 to
25 times longer than standard knives. The quality and accuracy of the products
are greatly improved, thus reducing rejections and increasing yields. With
knife changes reduced, regrinding costs are slashed.
Schönenberger
Megalife tungsten carbide is a new generation of carbide designed especially
for increased productivity.
Megalife carbide is a superfine micro-grain
material which displays an even higher wear resistance than our regular
carbide.
The advantages of Megalife
carbide over regular carbide:
Lasts 3 to 4
times longer between regrinds.
Improves
cutting quality while reducing dust.
Higher compressive strength of the micro grain
structure reduces the tendency of cutting edge nicking. |

Troubleshooting
TOP |
| Paper cutters
must be viewed as complete cuttings systems with many factors contributing to
the quality of the cut. Many cutter operators too quickly blame the knife or
the knife grinder for poor cutter performance when the fault is elsewhere. We
have listed some common problems encountered and their probable causes to
assist you in troubleshooting. |
WAVY CUT (A):
Vertical shading across edge of lift can be seen or felt as
wavy areas. |
| CAUSE: |
CORRECTION: |
|
Heavy print in certain areas causes thickness
differences across the sheets. This produces uneven clamp pressure in areas of
dense print. The knife finds these areas harder to cut since they are packed
tighter and deflect slightly. |
Evenly distribute clamp pressure by applying felt
or foam pad to face of clamp. |
|
Knife burned in grinding causing soft spots that
dull quickly. |
Regrind knife correctly taking off at least 1/16"
width to remove damaged steel. |
|
Knife angle too sharp causing deflection in high
density areas. |
Increase bevel angle by 2°, i.e., 22° to
24°. |
|
Inconsistent paper quality thickness. |
Change paper. |
|
WAVY CUT (B):
Diagonal shaded areas in direction of knife travel can be seen
or felt.
TOP |
| CAUSE: |
CORRECTION: |
|
Knife bevel too sharp and deflects
easily. |
Increase bevel angle by 2°, i.e., 22° to
24°. |
|
Knife burned in grinding causing soft spots that
dull quickly. |
Regrind knife correctly taking off at least 1/16"
width to remove damaged steel. |
|
OVERCUT:
Overcut is when the lower sheets in the lift are longer than
the upper sheets after trimming.
TOP |
| CAUSE: |
CORRECTION: |
|
Dull knife. |
Change knife. |
|
Wrong bevel. |
For soft paper, decrease bevel angle by 2°,
i.e., from 22° to 20°. For hard paper, increase bevel angle by 2°,
i.e., from 22° to 24°. |
|
Too much clamp pressure - as knife gets further
into lift of paper, the density increases causing deflection of
knife. |
Reduce clamp pressure. |
|
Back gauge not set square to vertical. |
Correct back gauge setting. |
|
UNDERCUT:
Undercut is when the lower sheets in the lift are shorter than
the upper sheets after trimming.
TOP |
| CAUSE: |
CORRECTION: |
|
Clamp pressure too low causing sheets to pull out
at bottom. |
Increase clamp pressure. |
|
Wrong bevel. |
For soft paper, decrease bevel angle by 2°,
i.e., from 22° to 20°. For hard paper, increase bevel angle by 2°,
i.e., from 22° to 24°. |
|
Rough or uneven material being cut, such as gummed
labels or embossed stock. |
Adjust clamp pressure. |
|
Back gauge not set square to vertical. |
Correct back gauge setting. |
|
HOLLOWCUT:
Sheets of paper are longer at ends and shorter in the center
(not cut square).
TOP |
| CAUSE: |
CORRECTION: |
|
Lift is clamped only at ends of paper and not in
the middle. |
Check clamp edge and apply felt or foam pad to
distribute clamp pressure. |
|
ARC CUT:
Sheets of paper are shorter at ends and longer in the
center.
TOP |
| CAUSE: |
CORRECTION: |
|
Lift is clamped only at center of paper and not at
ends of sheets. |
Check clamp edge and apply felt or foam pad to
distribute clamp pressure. |
|
KNIFE RUBBING:
Knife face rubs clamp causing scratches on knife face and
clamp.
TOP |
| CAUSE: |
CORRECTION: |
|
Knife dull. |
Resharpen knife more often. |
|
Knife too thick. |
Decrease knife thickness. |
|
Wrong bevel. |
Decrease bevel. |
|
Gibs worn on cutter. |
Repair machine. |
|
Combinations of above plus lifts too
high. |
Reduce size of lifts
being cut and look for
improvement. |
|
KNIFE NICKS
BADLY:
TOP |
| CAUSE: |
CORRECTION: |
|
Knife at wrong bevel. |
Increase bevel angle by 2°, i.e., 22° to
24°. |
|
Knife burned in grinding producing small heat
cracks which chip out. |
Regrind knife correctly taking off at least 1/16"
width to remove damaged steel. |
|
Knife set too deeply into cutting stick or stick
groove has trash in it. |
Rotate to fresh stick surface and set depth of cut
correctly:
(max. 0.1mm/.004"). |
|
Poor cutting sticks. |
Choose better quality stick. Use IKCO cutting
sticks. |
|
Contaminated chip board. |
Try increasing bevel, do not use carbide
knives. |
