Breton offers the Spiderbreton FR/PC 800 and FR/PC 1200 bridge saws, which are fully controlled by a personal computer, while the innovative control panel with touch screen display offers the simplest possible command interface, according to the company. The Spiderbreton FR/PC 800 can hold a diamond blade with a diameter of up to 800 mm, and all movements of the machine are powered by drives that are actuated by inverter and controlled by encoder. The sawing spindle is manually inclinable from 0 to 90 degrees, and the inclined cuts are plunged cuts or can be done by step cutting.
The Spiderbreton FR/PC 1200 can hold a blade with a diameter of up to 1,200 mm. All movements of the machine are powered by drives actuated by an inverter and controlled by encoder. The sawing spindle is automatically inclinable from 0 to 60 degrees in any position for cutting bevels by plunge cutting or step cutting.
Both machines can be supplied in versions with one or two worktables. In the double worktable configuration, a centrally located entrance to the work area is situated underneath the bridge guides. The hanging control console is located externally, and it can be turned toward the two worktables. A small, portable push-button panel enables the operator to control the movements of the axes from inside the work area of the machine.
With basic software, the Spiderbreton FR/PC bridge saws can saw slabs in an automatic cycle into rectangles and squares by using a series of transversal cuts (each one spaced as required), 90-degree rotation of the table and a series of longitudinal cuts (each one spaced as required). The shape of the slab gets â€œdefinedâ€ using a laser tracer, and the slab is displayed on the monitor along with the programmed sawing pattern, according to Breton.

The Record Due/600/36/200 gangsaw from Simec S.p.A. of Italy has a usable working width of 6,000 mm and 210 blades.
According to Simec, the company has invested heavily in the development and design of a product that would be a leader in the sector of gangsaws. â€œThe results are fully validating the achievement of that goal by obtaining a high rate of production,â€ the company stated.
Simec reports that there are several advantages to this type of machine, which can house three standard-sized blocks of granite under its blade-holding frame (or four slightly smaller ones). These are not limited to production increases, as they also make it possible to save on personnel and reduce the consumption of blades, metal grains and power, thanks to the entire redesign of the masses and dynamics of the gangsaw. Simec Record Due gangsaws are the only machines in the world equipped with curved columns and a double connecting rod transmission system, according to the company.
The curved geometry of the columns adopted by Simec on the entire line of granite gangsaws has the advantage of accompanying the blade-holder frame on its cutting run in a perfectly natural manner with respect to the length of the connecting rods.
On the Record Due model, considering the large size of the blade-holder frame, a double connecting rod transmission system has been used. In this specific type of configuration, the curved columns offer a further very important advantage: the two connecting rods - with their fixed dimension - are, by nature, perfectly synchronized with each other and do not require any complicated and often unreliable mechanisms to compensate for their movement.
â€œWith masses of this size, the smallest displacement of movement of the two connecting rods would cause dangerous vibrations of the blade-holder frame and tremendous stress on the entire structure of the machine,â€ Simec states.
In view of the results obtained with the new machines, Simec is already thinking of future models with a cutting width up to 10,000 mm.

Bergman Blair Machine Corp. carries the Montresor Lara 60-S2, an automatic edge polisher that has been specifically designed to meet the needs of companies looking for high production of straight, slanted and bullnosed edges up to 60 mm in thickness. The machine has a very sturdy steel structure that has been fully machined, sandblasted and then given an epoxy-based undercoat and enamel paint. Six mobile frontal heads programmed by accurate and synchronized mechanical transmission enable the Lara 60-S2 to produce all types of profiles, reports its manufacturer.
The machine can process bullnose profiles between 15 and 60 mm in thickness, which are obtained by the use of standard plane diamond wheels and do not require the use of profiled tools. The engagement and disengagement of the abrasive on the edge to be polished can be programmed even in the presence of irregular work pieces, and polishing of straight edges has been improved by the introduction of gentle rocking movement of the heads (plus or minus 2 degrees). With the use of a special diamond tool, a light bushhammering type finish can be obtained on straight or bullnose edges up to a maximum thickness of 60 mm. The frontal bar is no longer required, and the forward and reverse pressure controlling the abrasives is independent and does not require counter pressure. The conveyor belt slides over an interchangeable wear-resistant stainless steel surface and is fitted with a square cross-section guide way recessed into the work surface near the pressure units, thereby avoiding belt displacement during processing operations.
The Lara 60-S2 is supplied fully assembled and tested under working conditions.
