5. TYPE OF USE ALLOWED
5.1. MACHINE ADDRESSEE
This machine was design and built to comply a professional use, meaning that, besides the technical knowledge required,
it is necessary to have a specific knowledge to operate the saw to obtain the required goals.
5.2. OPERATOR
The saw operator should have experience on similar type of machine. People with low or none experience must be edu-
cated, followed and watched by a supervisor with enough experience and ability.
Therefore, the operator must be aware about dangers related to the use of this machine, and dangers due to normal han-
dling of metallic materials, similar, or heavy .
This machine cannot be used by people with handicaps or disables.
5.3. REGULATION
Designing and building this machine we respected the following laws and rules :
9UNI rules
9CEI rules
and more in detail, concerning the safety features (type A and B rules):

Material feeding speed Mt./m 30 300
Cutting bridge falling rate (w/o material) Mt./m 3 30
Bars size mm ∅13 ∅530
Bar weight kg. 0 1500
5.5. LIMITS USING THE SAW
The machine has two limits of use due to :
9operator’s inexperience
9material size and weight
The operator’s experience is particularly necessary when the saw runs in manual cycle ;
material size and weight must be within the ones above shown.
5.6. WORKABLE MATERIALS
This machine can cut only metallic bars, pipes and tubing. Every other use will is considered inappropriate use of the ma-
chine.
5.7. WORK AREA
This machine has to work in industrial environment. It is design to make mechanical machining under human control, but
the operator presence is not required continuously.
It is recommended to keep clean and free of interference the area close to the machine.
This machine use a mixture of oil and water as coolant liquid. Thus, the working area could be slippery and dirty.
THIS AREA MUST BE MARKED BY AN APPROPRIATE SIGNAL.
5.8. WORK PLACE
The machine has one work place in front of the control panel.
A second temporary work place is aside the vises, the register them, and to change the blade.
Each work place must be easy to reach when necessary, without interference, even temporary. The machine can work
automatically without operator, who must be present during the manual operations of loading and unloading, and control
the control panel operations.
No specific illumination is required, but the work place must be well illuminated to respect the requirements set by present
safety rules.
Only authorized people and maintenance personnel should be allowed to reach the saw work place.

INSTRUCTION &PARTS MANUAL Pag.17
Edition A
The operator must be equipped with personal protection instruments, like gloves and safety glasses.
5.9. COMMAND MODES,STOP,EMERGENCY STOP AND OUT OF SERVICE.
5.9.1 Command modes
The saw can be controlled in two different ways, turning or pressing a selector switch or a push-button (different ways for
different models). The switch enable a relay which insert the manual mode.
9Automatic mode ; the switch is on the automatic mode. All automatic commands are enable.
9Manual mode, the switch is on the manual mode. All the commands are switched to the control panel push-button
and switches.
5.9.1.1. Stop
The saw stops when the cutting cycle is over.
5.9.1.2. Emergency stop
The emergency stop stops the machine removing tension from the control circuit.
5.9.1.3. Out of service
The saw can be turned out of service removing tension from the control circuit, switching off the main disconnect switch
located on the front face of the enclosure. A signal saying “Out of service” must be placed on the machine, and it is opera-
tor’s duty to verify that the machine cannot generate danger situations.
5.9.1.4. Safety precautions
The machine cannot generate danger situation when it is completely without electric or hydraulic power.
Concerning the electrical power, the machine must be completely disconnected from electrical sources, turning of the elec-
trical socket on the building electrical panel. The machine cannot be considered completely safe if the only main discon-
nect switch of the machine is turned off.

9Hydraulic power unit
9Control Panel
9Coolant system
Pos. Tab 6.1. Base frame
6.1.1. Base frame
6.1.4. Vices
6.1.1. Base frame
The machine frame is welded and machined. The material used is Fe 37. In the weldment there are two reservoirs, one
for the coolant liquid, and the second for the hydraulic oil.
The frame is machined to avoid corners or abrasive points that could be dangerous. It is painted with two layers of paint,
the first of which prevent corrosion.
It is machined to be assembled with other machine components.
6.1.4. Vices
It includes :
9clamping vises, machined. Vises are controlled by hydraulic cylinders.

6.2.1 Cutting bridge frame
The cutting bridge frame is a steel Fe37 weldment; it is machined to be assembled with other machine components.
The bridge was design and built to endure the cutting strength, keeping enough sturdiness.
The frame is mechanically machined and painted with anti-corrosion agents and with nitro paint.
The blade is completely protected where it does not work. Covering the wheels, there are two doors that can be opened to
change the blade. Two safety switches are mounted on these doors, so to stop the machine if the covers are not in position.
The blade rotates on the wheels, one of which is driven, and the other one is idler.

INSTRUCTION &PARTS MANUAL Pag.19
Edition A
6.2.2 Guiding columns
The columns guide vertically the cutting bridge movement. They are made with chrome bars, hardened and grinded.
6.2.3 Columns connection
Made using a Fe37 steel plate, the columns connection connects and makes the guiding columns sturdier. It is fastened to
the columns through two bolts.
6.2.4 Lifting cylinder
This is an hydraulic cylinder, with chrome rod and lapped cylinder. The lifting cylinder is a double effect cylinder. The cyl-
inder head is attached to the cutting head, and the end head is fastened to the machine base frame.
6.2.5 Blade tension assembly
The C-M utilize an automatic band tension system. The proper band tension is assured by the cylinder.
The system has been designed to guarantee a proper tensioning of the band. (see 15.4 Band replacement).
6.2.6 Band drive assembly
The band is powered by an AC motor which automatically regulates the cutting speed. The motor is directly flanged on
the speed reducer: this application reduces vibration while providing best possible torque. On the other end of the reducer
there is the drive wheel, that is fastened to the reducer.
6.2.7 Band brush assembly
A band brush is powered by an hydraulic motor, and it cleans the teeth removing the chips.
6.2.8 Left and right band guides.
The band guides have to straighten the blade coming out the wheel, and keep it vertical helping the blade insertion between
the inserts.
Left guide arm : Moves horizontally on guides machined on the bridge, and it is moved by the movement of the vise.
Right guide arm : Fixed on the cutting bridge. It supports the cutting servo control.
Both the guide arms have carbide inserts.
6.2.9 Feed pressure control
The C-M utilizes a constant feed pressure control. The feed force is adjustable by turning the flow regulator valve, located
on the fix guide arm block.
6.2.10 Wheels
Made using cast iron G26, and lathe machined. They are fastened as follow :
9the idler wheel is fastened on the band tension assembly, and it turns on ball bearings ;
9the band drive wheel is fastened on the reducer shaft.
The wheels diameter is larger then the maximum material height that can be cut by the saw..
6.2.11 Band drive motor
The machine mounts a self-cooling 4Kw, AC electric motor.
6.3. HYDRAULIC POWER UNIT
The power unit is located in an easy to service spot of the machine frame. The valve manifold and solenoids lays on the
right side of the reservoir , over which the motor pump assemblies is installed. The power unit is made by :

Electrical motor and pump are connected by an elastic coupling.
6.3.2 Oil reservoir
It is in the machine frame, and it has a maximum and a minimum level indicators, and a suction filter. On the left side of the
infeed roller table there is a plug which allows to refill the reservoir. The hydraulic system has 2 filters :
9a 250 micron 45 liters suction filter
9a 60 micron 45 liters outflow filter
These two filters have to be removed when changing the oil for the first time (after 500 working hours), washed using tri-
chloroethane and dried blowing air.
6.3.3 Solenoid valves
The solenoid valves are mounted on blocks, and the control the hydraulic movements.
6.4. ELECTRICAL SYSTEM
6.4.1 Control console
The control console is on the upper part of the control enclosure.
6.4.2 Control enclosure
It is made bending metal sheets and it complies the IP55 standards. Inside there is the electrical panel which supports all the
electrical devices (relays, circuit breakers,...) complying the CEI 60204.1 standards.
