BOHLERSTRIP CUTTING RULES
Meeting the requirements of each cutting job in the optimal way, Bohlerstrip offers two basic categories of cutting rules:
through-hardened and edge-hardened rules.
 
Through-hardened cutting rules
Through-hardened rules have the same hardness in body and edge. Our specific tempering and decarburisation process achieves a specific rule structure, with a soft but deep decarburisation zone, which results in excellent bending properties. In general, Bohlerstrip cutting edge and bevels have a shaved finish for highest accuracy.

Hardness values and bending properties

All Bohlerstrip cutting rules show best decarburisation characteristics due to our special process. The amount of decarburisation strongly correlates with bending properties. Narrow angle bending without cracking is the result of a well controlled decarburisation process.

 

 
Bevel Profiles
To cope with the various rule requirements in die making Bohlerstrip offers the complete bevel range.
 
  CF – Centre Face, Centre Bevel
Center Face bevel has become the norm for cutting standard
packaging materials.
Standard edge angle: 53° (others on request)
 
  SF – Side Face, Single Bevel
SF bevels are best suitable for cutting thick materials where
a straight/vertical cut is required.
SF bevel is not available in “G” execution.
 
  CFDB – Centre Face, Double Bevel
This type of cutting bevel reduces the cutting force when cutting
hard/thick materials such as glass fibre reinforced laminates, leather,
cork, rubber, jigsaw puzzles, corrugated board, plastics, plywood.
CFDB bevel is recommended for multi-layer cutting.
 
  SFDB – Side Face, Double Bevel
SFDB profile offers the same benefits as CFDB bevel when cutting
thicker materials. The substrate is left with a square 90° cut edge
and all the distortion from penetration is left on the material waste.
SFDB bevel is not available in “G” execution.
 
Bevel Execution
To cater for the full range of applications, Bohlerstrip offers a large variety of bevel finishes.
 
  Shaved Cutting Bevel (S)
The standard bevel finish of Bohlerstrip cutting rules is a precision drawn
quality surface bevel.
These rules benefit from excellent bendability and height consistency.
 
  Sharpened Cutting Bevel (G)
For the professional cutting of plastics, rubber, laminates and coated materials a sharpened cutting edge has proven the best choice.

For these applications we recommend our high frequency hardened cutting rules in sharpened execution (UNIVERSAL 40, UNIVERSAL 60 and UNIVERSAL 75). The sharper cutting edge results in cleaner cutting faces, less knife wear and easy material penetration, at the same time reducing the cutting force. For thermoforming jobs we recommend UNIVERSAL 60 “G”.
 
  Polished Cutting Bevel (P)
Polished cutting rules combine the benefits of shaved and sharpened
execution in one rule.
– reduced dusting
– less friction when penetrating cut material, thus reducing cutting force
– improved bending properties compared with sharpened bevel
– rounded transition zone between bevel and body prevents material cracking
This execution is also available with polished double bevel (PL)
in CFDB or SFDB.
 
Coated Cutting Rules
Coated cutting rules provide various benefits such as reduced dusting, extended service life, less wear on cutting edge and bevel.
 
Supreme Dust Killer
Initially Supreme coating was developed for die cutting of labels, to prevent
glue sticking on rule bevel.

Many of our customers experience reduced dusting when using Supreme
coated cutting rules due to lower edge/bevel friction. At the same time
knife lifetime is extended.

Product Information:
The cutting bevel of the Supreme rule is coated with a thin anti-friction-film
which fills the microscopically small pores and marks on the cutting edge and
thereby adds to the smoothness of the bevel surface.
Supreme coated rules are offered in Universal and Universal 60.
 
 
Special Characteristics:
– reduces friction between
cutting edge and cut material
– dust-reduced cutting
– reduction of press force
 
Tinit (TiN)
TIN coated cutting rules are coated with a thin TiN layer of approx. 0.002 mm
on the cutting bevel only. The TiN coating hardness with 2,400 HV stands out
in comparison with standard UNIVERSAL edge hardness of  640 HV (4 times
harder).

Bendability, body structure, cutting profile and dimensions remain unchanged
and match with standard UNIVERSAL rules.

TINIT rule benefits:
– significantly increased knife lifetime
– productivity gains due to fewer die changes
– same bendability as uncoated cutting rules
– reduced dusting due to smoother bevel surface
– increased wear resistance when cutting abrasive materials
 
 
 
Generation X –
the new generation cutting rules
 

Label-X / Plast-X
The packaging industry is in permanent search for innovative designs and materials. The trend for UV-laminated and/or metallised boards as well as plastic packs requires new solutions in die cutting. To cope with these demands Bohlerstrip has developed a new series of cutting rules: Label-X and Plast-X. These new rules are processed on a unique prototype grinding machine applying razor blade technology, granting a super sharp cutting edge with superfine ground bevel (RA = 0.08 μm). These properties are important for efficient high quality die cutting of plastic materials, foils and parts in the electronics industry.

X-Press
The packaging industry is very competitive, and production costs are always a priority issue. Bohlerstrip has introduced X-Press, a truly sensational and innovative product:
X-Press is the most effective cutting rule to reduce make-ready time in the die cutting industry. X-Press has proven as very efficient tool to significantly boost productivity by reducing machine down time.

 

Label-X
The perfect choice for label cutting

Label-X – the new generation label cutting rule is perfect for die cutting of
labels due to its excellent cutting performance with superfine cutting bevel and
supersharp cutting edge.
Three versions offer the perfect cutting solution for the label industry.
LXS has the focus on extreme bendability at reduced body hardness while
LXH aims at maximum service life and stability due to its increased body
and edge hardness. LX represents the ideal compromise between
LXS and LXH.

X-Press
First patented self-levelling cutting rule – a worldwide success story

Bohlerstrip X-press cutting rule is a milestone innovation, helping reduce
make-ready time in die cutting operations. The innovative part lies in the back
of the cutting rule. The patented* micro-serrated rule back design serves as
‚pre-programmed‘ compensation zone which leads to quick self-levelling of
rules under pressure.
The rule back deforms, thus reducing the wear on the rule tip which helps
to keep the tip sharp and last longer.
* Patent AT508551B.
