2. MACHINE DESCRIPTION

2.1 WORKING PRINCIPLE

The benchtop Frame Assembling Machine Mitre Mite VN
Alpha has been manufactured to assemble any kind of frame.
The Mitre Mite VN Alpha , being of simple construction and
extremely easy to use, makes it possible to join with absolute
precision any kind of moulding by means of special steel V-

(R)

nails

.

It uses V-Nails

(R)

with the “pulling pow er” effect in dif ferent

sizes.

2.2 MAIN COMPONENTS

The main components constituting the machine are:

- Pneumatic clamping device to allow a proper locking

of the mouldings to insert several V-nails

(R)

in different

positions

- Magnetic pressure pads of several types, at quick

replacement, to have the proper clamping of an y profile

- Dual functions foot operating pedal for separate control

of clamping and nail insertion

- Pneumatic opening of the V-nail

(R)

magazine for a very

quick reloading

- Nail heads sizes 7, 10 and 15 mm.

2.3 MACHINE STRUCTURE

The movement directions during the machine working are
the followings:

- X AXIS

Movement of horizontal clamp

- Y AXIS

Movement of vertical clamp

2.4 DIMENSIONS

The overall dimensions are reported on table 2.9-A

2.5 SURROUNDING CONDITIONS

The machine does not need special surrounding conditions.
It has to be installed inside an industrial building, lit, aired
and with a compact and flat floor. The permitted temperatures
go from 41° to 104° F, with a humidity level not higher than
50% at 104° F or 90% at 68° F.

2.6 LIGHTING

Premises lighting must be conformed to the norms in force
in that Country where the machine is installed and has to
guarantee a clear visibility and can not create dangerous
light reflections.

2.7 VIBRATIONS

In standard conditions conformed to the indication of
machine proper utilization the vibrations do not create
dangerous conditions. The a verage quadratic weighed level,
according to the acceleration frequency to which arms are
exposed does not exceed 2,5 m/s2.

2.8 NOISE EMISSIONS

The machine is designed and projected for reducing the noise
emission level to its source. In standard working conditions
the Machine noise power level is:

Acoustic Continuous Equivalent weighed
pression A <70dB
Acoustic Istantaneous weighed
pression <130dB

The noise levels indicated are emission levels and are not
representative of operating levels. In spite of existing a
relationship between emission levels and exposure ones,
this can not be used in a reliable way to def ine if further
precautions are necessary. The factors determining the
exposure level to which the working force is subjected,
include exposure length, working premises characteristics
and other noise sources (number of machines, closed
building, etc…). Furthermore the allowed exposure levels
could change according to the several Countries. At any
rate, the information provided, will allow the Machine
Operator to achieve a better understanding of the dangers
and risks they are submitted to.

The indicated noise levels are emission
ones measured in standard conditions of
use. In case of any machine modification,
the above mentioned levels could be
changed and should be tested on the same
machine.
