MATERIAL
CLASSIFICATION AND
CHOICE OF TOOL

Since the aim is to obtain excellent cutting quality, the vari-
ous parameters such as hardness of the material, shape
and thickness, transverse cutting section of the part to
be cut, selection of the type of cutting blade, cutting
speed and control of saw frame lowering.These specifi-
cations must therefore be harmoniously combined in a sin-
gle operating condition according to practical considerations
and common sense, so as to achieve an optimum condition
that does not require countless operations to prepare the
machine when there are many variations in the job to be
performed.The various problems that crop up from time to
time will be solved more easily if the operator has a good
knoledge of these specifications.
WE THEREFORE RECOMMEND YOU TO ALWAYS USE
GENUINE SPARE BLADES THAT GUARANTEE SUPERIOR
QUALITY AND PERFORMANCE.
9.1 - Definition of materials
The table at the foot of the page lists the characteristics of the
materials to be cut, so as to choose the right tool to use.
9.2 - Selecting blade
First of all the pitch of the teeth must be chosen, in the other

words, the number of teeth per inch (25,4 mm) suitable for
thematerial to be cut, according to these criteria:
- parts with a thin and/or variable section such as profiles, pipes
and plate, need close toothing, so that the number of teeth
used simultaneously in cutting is from 3 to 6;
- parts with large transverse sections and solid sections need
widely spaced toothing to allow for the greater volume of the
shavings and better tooth penetration;
- parts made of soft material or plastic (light alloys, mild bronze,
teflon, wood, etc.) also require widely spaced toothing;
- pieces cut in bundles require combo tooth design.
9.3 - Teeth pitch
As already stated, this depends on the following factors:
- hardness of the material
- dimensions of the section
- thickness of the wall.
