2. MACHINE DESCRIPTION

2.1 WORKING PRINCIPLE

The Mitre-Mite VN 42 is a pneumatic frame assembling
machine particularly suitable with large sized frames.
The frame assembling machine Miter Mite VN 42 uses
V-nails with “pulling power” in different sizes.

2.2 MAIN COMPONENTS

The main components constituting the machine are:

• Frontal clamping device to have a perfect joint.

• Position brake to easily insert intermediate V-nails in

any profile

• Adjustable tilting fences.

• Floor stand

• Dual function foot pedal for separate control of clamping

and nail insertion

• 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 the 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 admitted temperatures
go from 41°F to 104°F (, with an humidity 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
situations.
The average quadratic weighed level, according to the
acceleration frequency to which arms are exposed does not
exceed 2,5 m/s2.

2.7 VIBRATIONS

In standard conditions conformed to the indication of
machine proper utilization, the vibrations do not create
dangerous conditions. The average 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 an existing
relationship between emission levels and exposure ones,
this can not be used in a reliable way to define 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 bldg,
etc…). Furthermore, the allowed exposure levels could
change according to several different Countries. At any rate,
the information provided, will allow the Machine Operator
to achieve a better evaluation of the danger and risks he is
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 checked on the
same machine.

4.6.1 Pneumatic connection

The Mitre-Mite VN 42 works by compressed air and is
controlled by a foot pedal & a thumb-button that allows the
activation of the frontal clamp,vertical clamp and V-nail
firing.

4.3 PRELIMINARY ARRANGEMENTS

To install the machine it is necessary to prepare a working
area adequate to the machine’s dimensions and the length of
moulding you will be using.

4.4 UNPACKING

The machin is shipped packed into an appropriate carton
and protected with polystyrene parts.
Remove the external packing and save it for future uses.
Check for any casual shipping damage and report them
immediately. Shipping damages or any other defects must

be reported to ITW/AMP within 3 days from the time
you receive the machine.

4.5 MACHINE POSITIONING

Position the machine in its working area. Adjust the height
of the machine by using the 4 screws. raise it up until you
reach the desired height (see fig. 2).

Attach your airline to the machine by using the provided
fast clutch fitting or a different fast clutch fitting suitable
with your pneumatic system.
Screw the fitting (see fig. 3-4) into the air filter located on
the right side of the floor stand.
Take the pressure gauge out from the floorstand and screw it
onto the air filter. Then connect your air supply line to the
