9.2 - Choosing the disk

First of all the pitch of the teeth must be chosen, suitable for the
material 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.

MATERIAL
CLASSIFICATION AND
CHOICE OF TOOL

9

Since the aim is to obtain excellent cutting quality, the various
parameters such as hardness of the material, shape and
thickness, transverse cutting section of the part to be
cut, choice of the type of cutting disk, cutting speed and
con-trol of head descent, must be suitably combined.These
spe-cifications must therefore be harmoniously combined
in a single operating condition according to practical consi-

dera-tions and common sense, so as to achieve an optimum
condi-tion 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 ti-me will be solved more easily if the operator has a
good know-ledge of these specifications.

WE  THEREFORE ADVISE YOU ALWAYS  TO CHOOSE
ORIGINAL SPARE DISKS THAT GUARANTEE SUPERIOR
QUALITY AND PERFORMANCE.

8.6 - Oil disposal

The disposal of these products is controlled by strict regulations.
Please see the Chapter on “Machine dimensions - Transport
- Installation” in the section on 

Dismantling.

8.7 - Special maintenance

Special maintenance operations must be carried out by skilled
personnel. However, we advise contacting THOMAS or their
dealer and/or importer. The term special maintenance also
covers the resetting of protection and safety equipment and
devices.
