SPECIFICATION of WALDFlex cutting rules

► Wald Bevel Configurator
Which cutting bevel should we use?
Here is the answer!

Characteristics of our rules

Good bendability "flex"-rules
High frequency hardened cutting edge for long runs
Deep decarburization will keep cracks away from the body on sharp corners
We have tried to find a good balance between Baenitic and Martensitic microstructure in our rules
Available in all common bevels C & S & F & SF.

Availability

From 22.80mm to 30.00mm in 2 und 3 Point
Bevel available in 30°, 42° and 52°
Facet bevel in 52/7°
in meter-lengths and coils

Hardness

Product	Body	Bevel in HRC (in HV)
WALDFlex (Standard)	35-36 (350)	57 (650)
Universal cutting rule, very good bendability, suitable for the most purposes (90%)
WALDFlex-SUPER	31-32 (320)	56 (620)
Very flexible cutting rule, for extreme bends, but still long life time
WALDFlex-DUR	37-38 (380)	57 (650)
Harder body structure for hard substrates, at R(min.) = 2.5mm still bendable
WALDFlex-QUATTRO	35-36 (350)	57 (650)
A special cutting rule developed fort hick materials or corrugated with coated surface, with facetted bevel in 42° top bevel, very well bendability

Explanation of our article code logics

WF = WALDFlex, C=Centre Bevel, F=Facet bevel, S=Side bevel

For example:
WFF-23.80-2-C-OP = WALDFlex, Facet Bevel 23.80mm 2pt in coils, opposite wound
or
WFC-23.80-2-GR= WALDFlex, centre bevel ~ ground edge, meter lengths
or
WFC-23.80-2-S-C-OP = WALDFlex-SUPER, 23.80-2pt, coil, opposite wound
and so on.

Bevel

Type C = centre bevel

Bevel type C

Linewidth:	0.71mm	1.07mm
Angle 1: Tolerance:	52° +0/-2°	52° +0/-2°
Centred M: Tolerance in mm:	0.355mm ±0.02	0.355mm ±0.02

Cutting angle: 52°
Top angle: 90°
Back facet: 0.60mm
Angle of facet: 2.5°

Type F = Double bevel with facet

Bevel type F

Linewidth:	0.71mm	1.07mm
Angle 1: Tolerance:	52° +0/-2°	52° +0/-2°
Angle 2: Tolerance 2:	7° +0/-0.5°	7° +0/-0.5°

Height and width tolerances

Height and width tolerances Height tolerance H = ±0.02mm

Linewidth	Width tolerance S
0.40mm	±0.015mm
0.50mm	±0.015mm
0.71mm	±0.015mm
1.07mm	±0.020mm
1.42mm	±0.025mm
2.00mm	±0.030mm

Flatness

Flatness Maximum tolerance:
X = max. 1µm/mm

e.g. H = 23.80mm:
X = 23.8*0.001 = 0.024mm

Twist

Twist Maximum twist
in 1.000mm max. 10°
