Changing The Cutters - Virutex EB135 Rapid Manual De Instrucciones

The working cycle of the edgebander for this type of edging is identical
to that set out in EDGEBANDING EDGES UP TO 1 mm, as explained above.
• EDGEBANDING EDGES OF 3 mm
Position of the controls:
Lever A (Fig. 6) in position 3, for edges of between 2 and 3 mm
Switch CM1 (Fig. 6) in position 4, cutting the edging with excess at
front and back
Switch CM2 (Fig. 6) in position 1, feeder and temperature control on
1. Place the board on the machine. Press on front panel S (Fig. 5) of
the control box and move towards the feeder so that it will take in
the board and convey it automatically.
2. When the board presses on micro-switch B (Fig. 21), automatic
feeding of the edging begins.
3. When the board reaches micro-switch E (Fig. 21), automatic feeding
of the edging is interrupted. This continues being dragged by the board,
and the trimmer and dust collector AS382L (if connected) start up.
4. When the board triggers micro-switch G (Fig. 21), blade H (Fig. 21)
of the end cutting unit retracts to let the board pass through without
front cutting.
5. When the back end of the board releases micro-switch B (Fig. 21),
being switch F (Fig. 21) pressed, the rear end of the edging is cut.
6. The trimmer stops when the back end of the board releases micro-
switch F (Fig. 21), and the dust collector also switches off after a few
seconds.
When micro-switch G (Fig. 21) is released by the back end of the board,
the blade of the front cutting is free to return to its initial position
when the board has passed through. The edgebanding cycle is complete
when the board has fully exited the feeder.
• FRONT AND REAR COMBINED CUTTINGS
Never try to raise the protector when the machine is
carrying out a front cut. The blade is very dangerous
and could easily cause an accident.
Front and rear cutting flush with the board: (For edging of up to 2
mm thick)
Switch CM1 (Fig. 6) in position 1.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut at
the back, flush with the board. Rear cutting.
If the rear cutting is not flush with the board, see Regulating the excess
at the back of the edging to correct the fault.
2. When board front reaches the blade H (Fig. 21), it moves it forward
and the excess edging at the front is cut flush with the board. Front
cutting.
Front cutting flush with the board and rear cutting with excess: (For
edging of up to 2-mm thick)
Switch CM1 (Fig. 6) in position 2.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut at the
back with a slight delay and an excess is left at the back of the board.
2. When blade H (Fig. 21) of the front cutting unit is reached by the
board, it moves it forward and the excess edging is cut flush with the
board. Front cutting.
Rear cutting flush with the board and front cutting with excess: (For
edging of up to 2 mm thick)
Switch CM1 (Fig. 6) in position 3.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut flush
with the board at the back. Rear cutting.
If the rear cutting is not flush with the board, see regulating the excess
at the back of the edging.
2. When the board presses micro-switch G (Fig. 21) blade H (Fig. 21)
of the front cutting retracts and lets the board pass through, without
cutting the excess at the front.
Front and rear cutting with excess: (For edging of 2-3 mm thick)
Switch CM1 (Fig. 6) in position 4.
1. When the back end of the board releases micro-switches B and C
(Fig. 21), being micro-switch D (Fig. 21) pressed, the edging is cut at the
back with a slight delay and an excess is left at the back of the board.
2. When the board presses micro-switch G (Fig. 21), blade H (Fig. 21)
of the front cutting retracts and lets the board pass through, without
cutting the excess at the front.
10. MAINTENANCE AND CLEANING

10.1 CHANGING THE CUTTERS

Before changing the bits, disconnect the machine from
the mains and lock the switch using safety cover K (Fig. 7).
The upper carbide cutter turns in a counterclockwise direction (-) and
the lower, in a clockwise direction (+), as shown on shavings collector
C4 (Fig. 9). Always keep this in mind when changing the carbide cutters.
Changing the upper cutter: Loosen the lever L1 (Fig. 22) and open
the feeder. Remove screws G1 (Fig. 17), take out copying device H1
(Fig. 18) and, using rod S1 (Fig. 19) to lock the spindle of the carbide
cutter, remove screw I1 (Fig. 19) which holds the carbide cutter in place.
Replace the old carbide cutter with a new one and put copying device
set H1 (Fig. 18) back together again, adjusting the height to suit the
finish of the edging with the carbide cutter inserted, as explained in
Adjusting the trimmer.
Changing the lower cutter: Gaining access via rear door F1 (Fig. 13),
loosen knobs B1 (Fig. 11) of the lower trimmer. Acceding now through
front door F3 (Fig.14) bring the head all the way down, with the aid
of knurled knob X (Fig. 9 and 11). To change the carbide cutter, pro-
ceed in the same way as described in the previous section, but bear in
mind that screw I1 (Fig. 19) has a left-hand thread. Once the carbide
cutter has been changed, raise the head fully once again, with the aid
of knurled knob X (Fig. 9), and regulate the copying device set to suit
the finish of the edging with the carbide cutter inserted, as explained
in Adjusting the trimmer.
Sharpening the carbide cutters: The carbide cutters should be shar-
pened, reproducing the original shape axially, without altering the
diameters (Fig. 24). To replace a carbide cutter that has been sharpened,
place as many 0.1-mm 7080013 washers as are necessary on the seat
at the back of the blade to compensate for the axial displacement
caused by the sharpening process.
10.2 CHANGING THE FEEDER BELT
Before changing the belt, disconnect the machine
from the mains and lock the switch using safety cover
K (Fig. 7).
Remove three screws T1 (Fig. 22) and take off the cover.
Loosen jockey wheel U1 (Fig. 23).
Replace belt V1 (Fig. 23) with a new VIRUTEX S.A. original, ensuring
that it engages correctly with the toothed wheels. Tighten the jockey
