4. GENERAL DESCRIPTION
OF THE RA17 VB MILLING MACHINE
The main function of the machine is to make grooves
and windows in doors for inserting isolation seals.
The machine is equipped with 2 kinds of guide and a
reversible angle that enable the making of grooves in
various positions as explained in the following sections
of this manual. It also has a centering pivot which faci-
litates the entry of the bit at the start of the operation.
The machine is also equipped with a suction nozzle
which can be used for connection to our AS182K,
AS282K aspirators or any industrial equivalent via the
ASPIRATOR CONNECTION TUBE No. 9 (Fig. 1).
The power cable can be fed through the brackets on
the dust collection tube to make the machine easier
to handle (Fig. 14).
5. TYPES OF MILLING
The grooves can be made in the moveable parts of
doors and windows as well as in the frames, which is
recommended for its simplicity. To control the gradual,
centered entry of the miller in the wood the machine
has a centering attachment F which is activated using
button E, (Fig. 6).
To begin a groove button E is pressed to the bottom,
and the machine is placed over the piece to be grooved,
supported by the rear part of the guide and the end of
the centering attachment F. Next, after starting up the
machine, button E is gradually released until the miller
is introduced in the wood and the guide is completely
supported, at which time we can begin moving forward.
In making the groove in the frame in order to reach into
the corners begin grooving at an intermediate point on
the frame or crosspiece. Make the groove to one end
then repeat the operation from the same starting point
working towards the other end.
5.1 GROOVES WITH 90° GUIDE (Fig. 11)
This guide is used for making grooves angled at 45° in
the cut-outs of frames or in windows.
5.2 GROOVES WITH STRAIGHT GUIDE
(Fig. 12 and 13)
Used for making straight grooves in the cut-outs of
frames or in windows.
It is possible to groove windows without having to
dismantle the fixed ones. (Fig. 12).
Using the angle, (Fig. 13), grooves can be made on smooth
areas such as the side of the hinges on the door at a
distance which can be adjusted from one side.
6. CHANGING THE GUIDES
Changing the guide (Figs. 2 and 3) is easily carried out

All manuals and user guides at all-guides.com
by removing screw B which holds it in place and pulling
it back as shown in (Fig. 3) until it has been removed.
The new guide is inserted in the same way.
On changing the guide, the depth of the groove is
maintained, which means that re-adjustment of the
tool is not usually required.
7. MOUNTING THE REVERSIBLE ANGLE
The reversible angle can be used for both sides of
the machine. For its assembly the 2 screws C must be
removed, (Fig. 4). Insert the reversible angle in the side
openings on the machine and secure it where desired by
supporting it against the body of the machine between
screws C and D. (Fig. 5).
8. CHANGING THE MILLER
Disconnect the machine from the mains
before carrying out this operation.
To change the miller (Fig. 7) block the motor shaft using
key H, unscrew the bolt with the key G and remove
the bit. Insert the new miller until its tip is within 43
± 1mm from the face of the bolt and re-tighten this
using the key.
The millers supplied by VIRUTEX are sharpened at both
ends.
9. CONTROLLING THE DEPTH OF THE GROOVE
Loosen screw K (Fig. 8) until the motor can be moved
by hand. Next turn the eccentric I with the service key
until the required measurement is obtained with the
help of the gauge J. When obtained re-tighten bolt K.
10. JOINTS
The use of VIRUTEX SILICON RUBBER JOINTS is recom-
mended for their high resistance to bad weather and
elasticity under load at temperatures between -60° C
and 200° C.
Types of joints:
