Used bridge cutting m/c, Gmm’s brand / mod.: BRIO Top
Mfng year: 2009
The ideal machine for small series works in industrial and small firms’ workshops, easy to use, compact and efficient. It can be
manually operated or it can perform automatically parallel, perpendicular and diagonal cuts using head’s orientation and the
interpolation of fast movements on recirculating ball slide guides. The TOP is a monoblock sawing machine that does not require
foundation, equipped with tilting table inserted in the structure to facilitate material loading.
The main structures of the machine – head-holder bridge, lateral shoulders (and slab holder table for the TOP) – 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 cast iron with a large size and very thick spindle carrier sleeve. The blade cover casing is in stainless steel with
plastic cover and the protections of the guides are all in zinc-plated 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 (X axis) of the blade-holder slide 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 (Y axis) is performed on guides with wheels permanently lubricated with grease, protected and positioned on the
supports made in electrowelded steel structure; the motion is operated by a couple of pinions and racks synchronized 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 (Z axis): the operating head slides vertically on a chrome-plated sleeve with inverter for the
optional copier. The upward and downward end of stroke are adjustable.
Head orientation (W axis) 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 axis X and Y. This machine automatically performs longitudinal cuts, transversal or diagonal
cuts according to the settings.
– TOP version: tilting table in hot zinc-plated steel with wood (or plastic on request) platform. The pneumatic tilting system of the
worktable allows easy loading of the slabs.
Otherwise the customer can create a working surface with a marble slab or concrete slab.
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 with twin function of
display and control and programming keyboard, USB key holder. A hinged arm holds the pushbutton station allowing the operator to
approach the table during work preparation. The software allows setting up to 9 different cutting measures that can be repeated up to
99 times with longitudinal, orthogonal and diagonal direction.
Optical collimator for easy positioning of the blade on the cutting line, installed on the blade cover guard, swivels with the blade itself.
Machine safety pursuant to EC standards with a photoelectric cut out barrier placed on closing gates controlled by an intrinsic safety
circuit protect the danger area around the blade. The blade-cover guard is internally soundproof coated. Safety pressure switch to stop
the machine in case of blade refrigeration water failure. Under-head sensor to stop the machine in case of overload due, for example, to
high forward speed or excessive stroke depth. Electrical and water supplies supported and protected by nylon cable-holder chains from
the connection point to machine base down to the electrical panel and from the latter to the operating head. The refrigeration water
supply system of the tool is automatically triggered.
