MONOBLOCK AUTOMATIC BRIDGE SAWING MACHINE
NEW GENERATION 180° ROTATING HEAD FOR BLADE UP TO 625 MM DIAMETER AND TILTING TABLE

Monoblock sawing machine that does not require foundations. The ideal machine for small series works in all types of workshops, easy to use, compact and efficient. It can be manually operated or it can perform automatically parallel, perpendicular and diagonal cuts using head orientation and the interpolation of fast movements on recirculating ball slide guides, without requiring the rotation of the table inserted in the single body and equipped with tilting table to facilitate material loading.

The main structures of the machine - head-holder bridge, lateral shoulders and slab holder table - are all in electrowelded steel structure, hot dipped zinc plating and stabilized to guarantee a perfect dimensional stability and long life. The blade-holder head is in hot zinc-plated steel with a large size and very thick spindle carrier sleeve. The blade cover casing and the protections of the guides are all in zinc-plated or stainless steel for longest duration. The superficial protection cycle of the machine consists of sandblasting and hot zinc plating of surfaces to guarantee perfect long-lasting corrosion resistance.

The horizontal motion cut/return of the blade-holder slide (axis X) operated by a pinion/rack couple is performed on hardened guides with recirculating ball pads specially covered by dust protection guard. The cut and return speeds of the blade-holder head have a separate electronic setting. The cut and return end of stroke are adjustable.

Bridge transfer (axis Y) is performed on oil bath roller guides, protected and positioned on the supports made in electrowelded steel structure; the motion is operated by a couple of pinions and racks synchronised and without clearance. The shifts are operated by brushless motors with variable speed controlled through the relative buttons or automatically with an adjustable program. The position of the bridge is displayed in tenths of millimetre on the display of the control panel.

Blade upward/backward motion (axis Z): the operating head slides vertically on a chrome-plated sleeve. The upward and downward end of stroke are adjustable.

Head orientation by 180°; from -45° to +135° operated by brushless motor and precision reducer gear without clearance.

The small size flanged spindle power unit directly connected to the blade has an efficient system of cooling water distribution. The machine computer processes all calculations to perform the cuts oriented in any direction on the slab, shifting at the same time the blade-holder head and the bridge on the guides (axis X and Y). This machine automatically performs longitudinal cuts, rotates the head and performs transversal or diagonal cuts according to the settings.

Tilting table in hot zinc-plated steel with wood or PVC covering. The pneumatic tilting system of the table allows easy loading of the slabs.

The electric panel is connected to the base on the right side of the bridge with the panel enclosing the basic controls, remote control switches, heat protections, general switch with door-lock and electronic control system.

The pendant pushbutton station containing the automatic cuts programmer, the display unit with 5" TOUCHSCREEN and the main controls, held by a hinged arm; easy to handle in the area between the panel and the table during the preparation of the work and it displays the programming steps and positions of the axes in motion. Possibility to set up to 9 different cutting measures that can be repeated up to 99 times with orthogonal and oblique direction.

Laser collimator for easy positioning of the blade on the cutting line, installed on the blade cover guard and rotates with the blade itself.

Machine safety: the devices comply with CE standards with a metal cable barrier and a micro-switch controlled by an intrinsic safety circuit protecting the danger area around the operating head. The blade-cover guard is internally soundproof coated. The power and water supplies are carried and protected by nylon cable-holding chains from the connection to the base of the machine to the electrical panel and from the latter to the operating head.
