GENERAL FEATURES
Multiple 1-head boring machine, dedicated to workings of horizontal, vertical and 45º boring, for the working of wood and materials with similar physical features.
Base and worktable
Structure in rolled steel sections, welded among them to create a large and rigid base of piece support.
Upright
Structure in steel of great thikness, adjustable in depth, that can support easily working stress. Pneumatic cylinders for the locking of pieces while boring.
Operating group
Boring head with quick connection chucks pitch 32 mm, with aluminium structure and motion distribution through gear cascad. Head boring movement through pneumatic piston..
Motion of piece and operating group
Automatic head motion for turnover (horizontal – vertical) of the operating group, with locking at 45°.
Bottom stops, side stops and extensions for long pieces, for the maximum working precision.
SAFETY RULES
In the basic standard composition, the machine already includes the safety guards for the countries where required.

STANDARD EQUIPMENT

Boring head with nr. 21 quick connection chucks and 5 tool-holder tins diam. 10 mm
Integrated suction system in the boring head, to keep the machine ambient clean from boring dust.
Operating group locking at 45°
Manual motion for turnover (horizontal and vertical) of the operating group.
Adjustment in height of the operating group through handwheel and mechanical digital indicator.
Adjustment of boring depth from 0 to 60 mm by 5-position revolver WITH AUTOMATIC DIFFERENTIAL OF HORIZONTAL/VERTICAL DEPTH TO AVOID PANEL BREAKING DOWN.
Adjustment of the descent speed of the boring group while working.
Group of adjustable side guides with cast iron support, supplied with metrical bar.
Side guide (length 3000 mm) with sickle stops for great panels. Installable instead of the existing guides, positioned at 90° as to the boring line and equipped with 4 excludible sickle stops (it can be also used like back guide).
Compass device – It allows to position quickly the opposite guide to that one used without reading the metrical rule.
N°2 upper pressure cylinders for piece clamping and n° 2 adjustable depth stops on millimetric scale

OPTIONAL
