Choice of blade
The different types of blade that can be used for the
TIGER 370 CNC---MR
must
in any case respect the following general characteristics:
H
“Fine tooth pitch”: for thin wall materials such as sheet steel, tubes and profiles;
H
“Coarse tooth pitch”: for large cross--sections; for soft materials (aluminium alloys
and soft alloys in general).
Tooth pitch
The choice of the most suitable tooth pitch depends on various factors:
H
the size of the section;
H
the hardness of the material;
H
wall thickness.
Solid sections call for discs with a coarse tooth pitch, while small cross---sections
require blades with finer teeth. This is because when cutting walls of small
cross---section (1÷7 mm) profiles, it is important that the number of teeth
actually making the cut should not be too small, otherwise the effect obtained will
be one of tearing rather than of swarf removal, leading to a large increase in
shearing stress. On the other hand, when cutting thick materials or solid sections
using an excessively fine tooth pitch, the swarf collects as a spiral inside the gullet,
and since fine tooth pitches have small gullets, the accumulated swarf will exceed
the gullet capacity and press against the walls of the workpieces, resulting in poor
cutting (same situation with soft materials), greater shearing stress and hence
breakage of the blade.
