3. Table rotating arm inclination adjustment
Loosen the three nuts nº11 (page 9) and adjust the rotating arm inclination, as per the necessary degrees,
which are shown in the arm ruler.
Once finished the adjustment, loosen again the three nuts.
4. Table turning adjustment (Extra equipment).
Unlock the locking command nº12 (page 9) of the rotating arm and adjust the table rotation. Lock again the
locking command nº12 (page 9) of the rotating arm.
It is important to make sure that the spindle is completely stopped before changing the speeds, not to
damage the driving gears.
5. Speeds
change.
The commands showed with nº3
(page 9) are the commands to change the speed. The different speeds are
shown in the plates, placed at one side of the above commands.
Advise
: Before the speed change, make sure that the spindle is completely stopped.
6. Drilling
depth.
To adjust the drilling depth, loosen the locking nuts nº25 (page 9) and turn the adjusting command of the
depth index nº18 in one or another direction. The indexing arrow nº18 (page 9) will show us in mm. or
inches, the drilling depth.
Once the regulation is over, re-tighten the locking nuts nº25 (page 9).
7. Automatic feed (Mechanical clutch).
Lt. is carried out by means of a light lateral displacement of any of the four-command nº2, as per drawing nº3
(page 4) clutching the power feed automatically, displacing the lever nº1 to the “C” position, as per drawing
nº3 (page 4). To obtain the different feeds, we will use the feed selector nº13 (page 9). The different feeds
are shown in the plate. There are two ways of disconnecting the power feed of the main spindle:
-
Manual release:
By means of the lever nº1. Place it in "D" position as per drawing nº3 (page 4).
-
Automatic release:
By regulating the drilling depth indicator arrow (see point 6).
8. Automatic feed (Electromagnetic clutch).
The automatic feed by electromagnetic clutch is released by pressing the push-button at the end of any of
the four-lever nº2, as per drawing nº3 (page 4) engaging the working feed automatically. To obtain the
different feeds we will use the feed selector nº13 (page 9), as per indicated on the plates. There are three
ways to release the automatic feed of the main spindle:
-
Manual release:
pressing the push-button at the end of any of the four-lever nº2, as per drawing nº3 (page
4).
-
Manual release:
pressing the “RELEASE” “STOP”, in the push-button plate nº17 (page 9).
-
Automatic release:
by regulating the drilling depth indicator arrow (see point 6).
9. Fine sensitive manual feed.
Place the feed selector nº13 (page 9) in "O" position (dead point). Clutch the power feed as per stated in
points 7 and 8 (depending on the machine, whether it is mechanical or electromagnetic). In this way, by
manual rotation of wheel nº23 (page 9), we can work with the fine sensitive manual feed.
10. Pair limiter
To avoid breaking in the mechanisms (for example in over loading cases), the machine is provided with a
pair limiter in the feed box. If for any reason we need to adjust the pair limiter, we have the
nut nº25 A/583
(page 11A).
11. Automatic tool ejector
Pull from command nº3 and place in "B" position, as per drawing nº2 (page 4), adjust the tool with your left
hand and with your right hand give a dead blow in clockwise sense with command nº2 (page 4) in the upper
part of the main spindle stroke. As per drawing nº3 (page 4).
Advise:
It is important that the command nº3 (page 4) is always in "A" position for working operations (See
drawing nº2).
12. Shank locking
Loosen with an Allen key the screw nº25 (page 9).
Advise:
We recommend you to use it only for milling operations.
