17.5 HEAD POSITIONING FOR LINE BORING
POINT 1
: to position spindleheads from zero position (A reference stop), do as follows: Position counter of
head n°1 at desired height by operating on (B) crank and likewise set height of head n° 2 by operating on (C)
crank. Make sure the heights correspond to heights of piece to be bored.
POINT 2 : insert the chosen drills on the spindles and monitor the direction of rotation of each spindle.
POINT 3
: set holes depth by operating on the devices of each head (refer to paragraph 16.3).
HOW TO POSITION THE STOP TO START THE WORKING CYCLE
This boring machine comes with an extension fence with millimetrical scale related to drills, which makes it
possible to determine the starting edge for line boring. Position the extension fence stops in the predetermined
points, taking into account piece height. Positions can by obtained by calculating the overall distance from one
point to the other or by using instruments. The extension fence can be equipped with a separate instrument
(Fixed gauge) to bore longer rows of holes than the ones the boring machine can usually bore. Also refer to
paragraph 16.7 – HOW TO USE REFERENCE PIN.
HOW TO POSITON HOLD DOWN CLAMPS
Once the machine is ready, hold down clamps units must be positioned exactly over the boring points before
starting boring operations. To position hold down clamps manually move the bars (A+B) in the desired position
and lock them by clamping the handles (C). Hold down clamps are then laid on the piece to be bored by oper-
ating on each handle (D).
BORING OPERATIONS
Position the piece to be bored on the working table and lean it against references. Make sure electric and
pneumatic connections are operational. By pressing the pedal (E) it is possible to simultaneously lock the
piece into position, start the engines and feed drills at working speed. Each time you reset your boring ma-
chine, it is advisable to simulate a working cycle with a scrap wood panel to make sure size is correct and that
the machine is in good working order, without damaging a good wood panel.
