foundry for re-smelting after having removed the contents
(classified in point 3);

2) electrical components, including the cable and electronic ma­terial (magnetic cards, etc.), fall within the category of material
classified as being assimilable to urban waste according
to the laws of the European community, so they may be set
aside for collection by the public waste disposal service;

3) old mineral and synthetic and/or mixed oils, emulsified oils
and greases are special refuse, so they must be collected,
transported and subsequently disposed of by the old oil
disposal service.

7.3 - Head return stroke limiting device

It consists in a mechanical adjustment system, mounted paral­lel to the head rise cylinder, to reduce the passive phases of the
operating cycle, in other words to eliminate the idle stroke that
takes place when the size of the part to be cut is much smaller
than the maximum cutting capacity. Practically, you adjust the
starting position of the disk in proximity of the part, independently
of its dimensions.

7.4 - Restoring oil level in motorhead com­pensation cylinder tank

- Braking fluid in the cylinder controlling the head, may consume
through the time.

- It is therefore important to restore the oil quantity inside the
compensation tank by removing the plug and then using a
syringe type injector to fill the tank.

- First, take the head to the upper position and disconnect

airs upply from the pneumatic system (disconnect the air
pipe from the machine). Switch on the machine and push
the Line button.

- Add oil making sure that the selector ( 5 ) is switched to the
right (head downfeed).

- Add oil until the rod, corresponding to the second mark on the
stem, has come out completely.

- Air must be bleeded from the tank by loosening the screw
located on the side of the cylinder (see arrow) until some oil
pours out (always keep the selector ( 5 ) to the right); when
this has been done, secure the screw, remove the injector
and put back the plug.

- Connect the machine to the pneumatic system.

- Use SHELL hydraulic oil 32 or similar.

7.5 - Piece-Counter

To carry out this operation you must:

- slightly open regulator.

- Rotate the selector ( 5 ) either to the right or left to lower or lift
the motorhead.

- position and secure the mechanical stop ( 8 ) against upper
plate of the cylinder, so as to press the upper limit micros witch.

- the lower limit switch ( 9 ) is set during inspection and lim­its the lower stroke of the motorhead. Do not change this
setting.
ATTENTION:

- It is not necessary to adjust the upper end-stroke everytime;
one can bring the disk near to the workpiece by means of
selector ( 5 ) and then start the automatic cutting cycle
wich will take place from the actual position of the disk.
Do notice that, once the cut is completed, the motorhead
will go to the upper end-stroke ( against the relevant
microswitch ).

- operate on regulator to modify motorhead return speed.

- Press Reset (A) and hold to release the Lever (B).

CHOICE OF TOOL

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
control of head descent, must be suitably combined.These
specifications must therefore be harmoniously combined in
a single 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 ADVISE YOU ALWAYS TO CHOOSE
ORIGINAL SPARE DISKS THAT GUARANTEE SUPERIOR
QUALITY AND PERFORMANCE.

9.2 - Choosing the disk

First of all the pitch of the teeth must be chosen, 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.

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.

9.4 - Cutting and advance speed

The cutting speed (m/min) and the advance speed (cm2/min =
area travelled by the disk teeth when removing shavings) are
limited by the development of heat close to the tips of the teeth.

- The cutting speed is subordinate to the resistance of the
material (R = N/mm
dimensions of the widest section.

- Too high an advance speed (= disk descent) tends to cause
the disk to deviate from the ideal cutting path, producing non
rectilinear cuts on both the vertical and the horizontal plane.

), to its hardness (HRC) and to the

9.5 - Running in the disk

9.7 - Type of disks

The disks differ essentially in their constructive characteristics,
such as:

- Tooth shape

- Tooth cutting angle

Tooth shape

The profile of the toothing depends on the size, shape and
thickness of the section to be cut, either straight or at an angle.
It may also vary according to the pitch, but not so distinctly as to
make this an element for classification.

- Fine toothing is to be chosen for cutting small sections with a
profiled shape and tubular sections with thin walls (2-5 mm
depending on the material).

- Large toothing is suitable for cutting medium and large solid
sections or fairly thick profiled or tubular sections (o ver 5 mm).

"A" toothing:
normal fine toothing

"B" toothing:
normal large toothing with or
without shaving breaking inci­sion

“C (HZ)” toothing:
large toothing with roughing
tooth with rake on both sides,
alternating with a finishing
tooth without rake. The rou­ghing tooth is 0.15-0.30 mm
higher

Tooth cutting angle

Each tooth has two cutting angles:

α : front rake angle

γγ

γ : rear rake angle

"AW" toothing:
fine toothing with alternate

"BW" toothing:
large toothing with alternate

Added toothing:
disks made in this way are
used for cutting non-ferrous
metals, such as light alloys,
and plastics, and above all in
wood-working. The teeth are
hard metal (HM) plates brazed
onto the body of the disk; there
are various types and shapes
and, considering the vastness
of the field, the topic is not
developed further here.

When cutting for the first time, it is good practice to run in
the tool making a series of cuts at a low advance speed

(= 30-35 cm
to the cutting capacity and solid section of normal steel with
R = 410-510 N/mm

with lubricating coolant.

9.6 - Disk structure

The most commonly used disks are made of extra high speed
steel (HHS) of normal quality (HHS/DMo5) or superior quality
(HHS/Mo5 + Co5) with a treated tooth, which differentiates them
from the former on account of the high value of structural
resistance, greater resistance to seizing, absence of stress in
the mass and a better holding of lubricating coolant during work.
