Saw Blade Design
The prerequisite of the correct cutting power of the machine is the use of high-quality saw blades. In order to achieve a high cutting
power, it is recommended to use bimetallic saw blades. The main saw blade component is a high-quality heat treated steel with a high
elasticity limit. The tooth edges are high-speed steel of the following quality: M 42, M 51.
M 42
- a saw blade for universal use for cutting metallic and non-ferrous materials within the whole range of quality classes up to the
45 HRC hardness. The saw blade is suitable for cutting full materials of all cross-sections and diameters, profiles, pipes and bundles.
M 51
- with reference to the M 42 saw blade, the M51 is designed first of all for cutting steel up to 50 HRC, steel of higher strength
classes, acid-resistant and stainless steels. Futhermore, for cutting nickel, titan alloys and special grade of bronze.
Carbide
- high cutting power as compared to bimetallic saw blades. Suitable for cutting of steel, non-ferrous metals, material with
high content of chrome, nickel, titan, stainless steel and face-hardened materials up to 62 HRC. The saw blades can be used for all
materials including stainless steel, tool steel, non-ferrous metals, cast iron, plastics and fibreboards. Characteristics of these saw
blades include a high thermal conductivity, high wear and tear resistance and thus longer life, higher cutting speed, less frequent saw
blade replacements and better productivity as compared with carbon steel saw blades.
Design: M 42 - composition: W 2%, Mo 10%, V 1%, CO 8%, tooth hardness: 68 HRC. For cutting of materials up to 45 HRC
Design:
M 51 - composition: W 10%, Mo 4%, V 3%, Co 10%, tooth hardness: 69 HRC. For cutting of materials up to 50 HRC
Design: Carbide - tooth hardness 1600 HV. For cutting of materials up to 62 HRC.
In addition to standard shapes and sizes of teeth, the saw blades are also manufactured with special features, such as saw setting,
tooth angle and tooth face shape, which are used particularly for cutting of specific materials. Please contact your saw blade supplier
to get more information about these features.
Saw Blade Tooth Arrangement
a)
Constant
- tooth edge spacing always equal
b)
Variable
- the tooth edge space is different, repeating periodically. This modern saw blade design enables a bigger cutting range in
one saw blade type. It is able to eliminate vibrations caused by the tooth edge touching the material and thus to achieve a clean
smooth cut and longer service life.
