Machine presentation
TIGER 370 CNC---MR is an electromechanical pneumatic saw, which cuts metal
profiles and solids. It can operate in SEMIAUTOMATIC or AUTOMATIC
mode. In Semiautomatic mode, after setting the cutting head stroke and the head
downstroke speed on the control panel, position the vice 2÷3 mm from the
material being processed and press the start button on the control panel to
activate the disk (or foot pedal if supplied);

til the cut is made
(FCTA)
3. The head returns to

In Automatic mode, after setting the cutting head stroke and the head downstro-
ke speed on the control panel, position the vice 2÷3 mm from the material being
processed and press the start button on the control panel to activate the disk (or
foot pedal if supplied):

Functional parts
TIGER 370 CNC--MR model
In order for the user to move towards a full understanding of how the machine
works, which is described in detail in the chapter 5, this chapter deals with the
main units and their locations.

Cutting head
The cutter head makes the cut. It is contained inside guards preventing accidental
contact with the tool and moving parts. It is moved by an electro---mechanical
cylinder (step motor), and runs on a twin linear guide with ball---bushing sliding
blocks. This system makes the structure highly rigid, providing a better cutting
finish with less vibration and noise.
Cutting vice
The vice is the unit that clamps the workpiece during cutting; it consists of a vice
support, commonly known as a “lead nut” fixed to the work table on which a
mobile jaw is mounted. The vice is operated manually by a handwheel and locked
by a Pneumatic cylinder.

8Functional parts
Control Panel
The control panel has a protection rating of IP 54 and contains the electronic
equipment. Access to the control panel is protected by a safety panel mounted on
hinges and fastened with screws, specially designed to prevent tampering. The
control panel swivels on two articulated joints so that it can be positioned by the
operator for greater ease---of---use and safety.
Feeder
The material, locked by means of the pneumatic vice, is delivered by a carriage
which conveys it along ground guides. The numeric check controls, with great
precision, the step motor of the infeed carriage, enabling the operator to set, on
the same bar, 32 batches of pieces to be cut, each with different amounts and
lengths.The material, locked by means of the pneumatic vice, is delivered by a

Base
This unit features a large coolant collection surface which conveys the coolant to
the rear tank via the tank cover, and a swarf collection drawer. An electric pump
is housed inside the tank which draws the clean fluid from the filter system.

Safety and accident
prevention
The TIGER 370 CNC---MR has been designed and produced in accordance with
European standards. For the correct use of the machine we recommend that the
instructions contained in this chapter are carefully followed.
Use of the machine
The TIGER 370 CNC---MR circular saw is designed to cut exclusively non---fer-
rous profiles and solid metal sections. Other types of material and machining are
not compatible with the specific characteristics of the saw. The employer is
responsible for instructing the personnel who, in turn, are obliged to inform the
operator of any accident risks, safety devices, noise emission and accident
prevention regulations provided for by international standards and national laws
regardingtheuseofthemachine.Theoperatormustbeperfectlyawareofthe
position and function of all the machine’s controls.The instructions, warnings and
accident prevention standards in this manual must be respected without question
by all those concerned.The following definitions are those provided for by EEC
MACHINES DIRECTIVE 2006/42/CE :
H“Danger zone”: any zone in and/or around a machine in which the presence of a
person constitutes a risk for the safety and health of that person.
H“Person exposed”: any person finding himself either completely or partly in a
danger zone.
H“Operator”: the person or persons given the responsibility of installing, operating,
adjusting, maintaining, cleaning, repairing or transporting the machine.
The manufacturer declines any responsibility whatsoever, either civil or crimi-
nal, should there be unauthorised interference or replacement of one or more
parts or assemblies on the machine, or if accessories, tools and consumable
materials are used that are different from those recommended by the manu-
facturer itself or if the machine is employed in a plant system and its proper
function is thereby altered.
General recommendations
LIGHTING
Insufficient lighting for the types of operation envisaged could constitute a safety
hazard for the persons concerned. For this reason, the machine user must provide
lighting in the working area sufficient to eliminate all shadowy areas while also
avoiding any blinding light concentrations. (Reference standard ISO 8995---89
”Lighting in work environments”).
CONNECTIONS
Check that the power supply cables and pneumatic feed systems comply with the
maximum machine absorption values listed in the “Machine Specification” tables;
replace if necessary.
