FLAT BED DIE CUTTING
Industrial and consumer goods are delivered to end users and commercial enter-prises in adequate packaging.
Packaging, especially folding carton boxes, offer protection for the product and also ensure that the goods are delivered safely. Over the last few decades we have seen a steady increase in the use of packaging as an advertising media to increase the product image as well as the corporation behind them.
To ensure the required quality of the finished product cartons are processed on high precision converting machines. The applied method of flat bed die cutting allows for high speed converting and accuracy of the packaging material.
Cutting dies are hi-tech tools produced with the help of state-of-the-art automatic steel rule processors as well as laser and water-jet machinery.
Basic requirement for optimum cutting results is the use of high precision cutting & creasing rules.
BÖHLER is your reliable partner when it comes to steel rule competence. BÖHLER steel rules are 100% made in Austria/Europe!

PRODUCTION RANGE
Böhler cutting, scoring and label rules are separated into two main groups, illustrating the optimum properties for the respec-tive applications:
Through-hardened Rules:
These rules have a uniformly high hardness on the cutting edge and in the body. Special heat treatment produces a particu-lar grain structure and a soft, ductile outer skin, which facilitates the required bendability. The cutting edge is usually shaved (longitudinally worked), with a very high dimensional accuracy.
This all-purpose steel rule from BÖHLER offers good bendability and is suitable for low runs.Used for:Cardboard, corrugated board, …
TOP
A very hard rule, which can be bent to 85° due to controlled surface decar-burisation. It offers the highest stability and performance during difficult cut-ting operations.Used for:Gaskets, rubber, plywood, cork, felt, beer mats, …

HARDNESS VALUES AND BENDING PROPERTIES
BÖHLER K-BACK
Cutting rules with flat (rectangular) back eventually create problems when bending narrow angles because of the bulging effect on the cutting rule back.
The unique BÖHLER K-back (compensation back) minimizes this effect and offers various benefits:
• Minimizing of rule back deformation without broaching necessity (height compensation)
• Self levelling of the rule when high cutting force is applied. The rule back is flattened slightly
• Knifes with round back execution fit easier into plywood slots in comparison with square shaped rule backs

TYPES OF CUTTING BEVELS
In order to meet with the various cutting applications, we offer the complete bevel range.
SFDB – Side Face Double BevelThe SFDB profile offers the same advantages as the CFDB when cutting thicker materials. SFDB has the advantage that the substrate is left with a square 90° cut edge and all the distortion from penetration is left on the material waste. Not available in “G” execution.
CF – Centre Face (Centre Bevel)The CF-bevel is the most commonly used symmetric cutting edge for standard cardboard.
Standard edge angle: 53° (others on request)
SF – Side Face (Single Bevel)This type of cutting edge is particularly suitable for cutting hard materials (gaskets, displays and close shapes). The minimum counter bevel facilitates a right angled, straight cut.
CFDB – Centre Face Double BevelThis type of cutting edge reduces the cutting force required when cutting hard and/or thick materials, such as glass fibre reinforced laminates, leather, cork, rubber, jigsaw puzzles, corrugated board, plastics, plywood, etc.

CUTTING BEVEL FINISH
S: Shaved (drawn) Cutting Bevel
The standard finish of BÖHLER cutting rules is a precision drawn quality surface bevel.The prime benefits are excellent bendability and rule height consistency.
P: Polished Bevel
Polished cutting rules combine the benefits of shaved (drawn) and ground (sharp-ened) execution in one rule.
The result is a very smooth (fine grain) surface offering:• dust reduction• less friction when the rule penetrates into the cutting material• cleaner cutting faces• improved bending properties in the rule top edge compared to ground
execution• rounding off the transition zone between cutting bevel and body
This execution is also available with polished double bevel (PL) in CFDB and SFDB.
G: Ground (sharpened) Cutting Bevel: (G)
For the efficient cutting of plastics, rubber, laminates and coated materials, a ground cutting edge has proven the best.For these applications we recommend our induction hardened cutting rules (UNI, UNI 60 and UNI 75) in ground edge finish.Ground finishing guarantees a sharper cutting edge resulting in cleaner cutting faces, less knife wear and therefore easier penetration into the cutting material, thus, reducing cutting force.For thermoforming jobs UNI 60 “G” is highly recommended.

COATED CUTTING RULESIn general coated cutting rules provide several advantages such as reduced dust, longer tool life and less wear on rules and counterplates.

soft, ductile
SUPREME coating
TINIT coating
~ 0,001 mm
BÖHLER CUTTING RULES
The Supreme cutting rule was originally developed for the label industry with the goal to restrict the build-up of adhesive on the cutting edge. This type of rule is now used successfully in a variety of applications. It has gained reputation for dust-reduction for boards with increased recycled fibre content.Supreme-coating significantly reduces mechanical wear and tear on the cutting edge thereby considerably increases the cutting die lifetime.In the same way the required press force is substantially lowered, which contributes considerably to extending the life of expensive automatic platens.
Product Information:By means of a special process 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:• dust-reduced cutting• reduction of press force thus less wear on die cutting equipment• reduction of friction between cutting edge and cutting material• substantially increased service life of the die
Tinit cutting rule bevels are coated with a thin TiN-layer of approx. 1 micron. The unique feature of TINIT coating is its extreme hardness of ~ 2400 HV based on a hardened cutting edge with ~ 640 HV.
Bendability, body structure, cutting geometry and dimensions are compa-rable to our standard Böhler Universal rule. TINIT is available in shaved exe-cution, in CF and CFDB (double bevel) and optional in Universal 60.
TEFLON
For sensitive applications we offer Teflon coated rules on basis of BÖHLER UNIVERSAL. Teflon coating reduces significantly sticking effects in the die cutting process. Teflon also supports anti-bacteria effects. Teflon is available in 1.000 mm lengths.
TINIT (TiN)
TINIT rule benefits:• significantly increased die lifetime• higher efficiency in the converting
process• increase in productivity due to
fewer die changes• higher wear-resistance on cutting
edge • same good bendability as uncoat-
ed rule• less dust in cutting process

Conventional Creasing of Plastics:
• Local reduction of folding resistance by decreasing the material thickness, no creasing matrix is used.
• Creased parts may bulge, which create problems in automatic folding and gluing machines.
• Hot-creasing technology gives better results, but is expensive.• Creased plastic sheets may develop micro-cracks upon folding, visible as
milky shades in the material.
Plastic-Crease:
• Very localised reduction of folding resistance prevents micro-cracks and “whitening” of the creasing track.
• Plastic-Crease creates less material displacement, creased parts therefore remain flat.
