4. DESCRIPTION OF THE MACHINE
Our Boring Machines have been manufactured to make a series of holes at a fixed 32-mm distance be-
tween centres on wooden pieces (with maximum precision).
The head has its fulcrum on the machine table and it can be tilted until a 90-degree angle. The pieces to
be bored are fed by the operator, who places them on the machine table. The operator will carry out the
required adjustments by pressing the control pedal before locking the pieces into place with the relevant
hold down clamps and starting boring operations.
The following parts make up the machine:
•
A steel frame structure
•
Spindlehead unit with transmission and drill spindles with quick-change seat (standard).
•
Hold down clamps unit to clamp the piece to be cut in a vertical position.
•
Pneumatic system for head positioning and head feed.
•
Back stops so as to obtain the same vertical and horizontal boring distance
•
Crank mechanism to adjust spindles height, equipped with mechanical counter and quick-depth de-
vice to adjust hole depth from 0 mm to 100 mm.
4.1 APPLICABLE TOOLS
Quick-change spindle drills with a 10mm-diameter shank L=20mm.
Drills up to 40mm-diametre outside the rack can be used; 100 mm maximum working length (attachment
is not taken into account).
REMOVING OR TAMPERING WITH SAFETY DEVICES MAY CAUSE SERIOUS ACCIDENTS. IT IS
FORBIDDEN TO REMOVE, EXCLUDE OR MODIFY SUCH DEVICES. PERIODICAL CHECKS
