Whether a fabricator is operating a large- or small-scale operation, the bridge saw serves as the backbone of their processing operation. The bridge saws on the market today are continuing to advance, offering new features and benefits for fabricators that speed production time while offering optimum quality in fabrication. Some of these introductions are new variations of existing machines, while others are completely new models.

Here is a look at some of the new innovations in bridge saws currently on the market.

AGM's new CNC saw, the Optimaster, is fully automated and uses a CAD-CAM system to write and store programs. According to the manufacturer, this saw represents a true breakthrough for the industry since it allows fabricators to design and operate a truly automated shop. The CNC saw also increases productivity because of its highly automated nature; it is programmed similarly to a CNC router and uses a CAD-CAM system to locate and optimize cuts on slabs. The unique advantage of AGM's CNC saw is the seamless connection between its CNC saw, routers and waterjet as each machine uses the same CAD-CAM system. This simplifies operator training and streamlines production since only one CAD-CAM system is needed, reports AGM. The Optimaster also uses a camera system, which helps operators to optimize cuts and material, saving time and money. For special cuts and small quantities, the saw can also be operated in manual mode.

AGM also offers a turnkey solution that includes the Template Master templating system, the Intermac Master 33/43 CNC router and the AGM Masterjet 3600 waterjet. By combining the templating system and the Optimaster, fabricators will be able to reduce templating errors, reduce production times and increase overall production efficiency, the company reports.

The Achilli MBS 3000 CE offered by Braxton-Bragg Corp. handles full-sized slabs with a useful cut of 10 feet, 2 inches. It comes standard with a control panel and pendant control with a 20-foot cord. An optional water-recycling tank with pump is available. Weighing in at 3,916 pounds, the MBS offers a table size of 12 feet, 8 inches x 7 feet, 3 inches that consists of a replaceable marine plywood bed with electrically driven hydraulic pop-up rollers to facilitate slab positioning. Because the MBS does not need a turntable, tremendous space is saved in the shop, allowing for better use of floor space. The special engineered design of the saw has proven to be extremely strong and sturdy, guaranteeing straight X and Y cuts. Additionally, the design took safety into consideration, as visibility is 70% greater than that of saws placed on block wall foundations. The wood base is very durable, allowing for hundreds of slabs to be cut before exchanging. In most cases, the wood boards can be turned over for double life. Once the life of the boards are spent, they can be exchanged in 1⁄10 of the time that it would take to redress or re-pour a standard concrete-based bed or turntable, according to the manufacturer.

The Sierra can process full slabs up to 7 cm (2 3⁄4 inches) thick over its generous 12 feet of gantry travel. The Sierra is sized at 15 feet, 10 inches long x 16 feet wide x 6 feet, 6 inches high, and it features heavy-duty construction and proven industrial-duty components to assure extended saw life and superior cutting accuracy.

The Sierra uses either a 14-inch diameter blade for granite sawing or a 16-inch diameter blade for sawing marble. A powerful 10-hp electric main motor (15-hp option available) directly drives the saw arbor for more efficient energy transfer to the blade. Variable speed cutting motion abilities, combined with the rack and pinion drive, provides cleaner cuts and extended diamond life in the blade. The 6-inch powered variable speed rise and fall of the blade allows for precise cutting and accurate vertical blade positioning. The entire bridge may be indexed from 0 to 47 degrees with hard stops for mitering, without the need for repositioning or jig fixtures.

The new bridge saw Thibaut TC 04 Numeric, available from EuroStone Machine is part of the new generation of “intelligent” machines. Simple to use and “comfortable,” the TC 04 Numeric is a step towards greater autonomy and creativity, according to the manufacturer. Sawing is considered a critical and complex phase requiring excessive time (precision, multiple handling operations, waiting time between cuts). The TC 04 Numeric makes processing easy, with menu-driven programming and logical icon selection. Rectilinear, orthogonal or curved cuts are made automatically.

A 360-degree rotating head replaces the rotating turntable and permits automatic (or manual) sawing in all directions. This means not only quicker cut-to-cut sawing, but also a smaller and more compact footprint. The operator may also program internal cuts (cook-top cut-outs and similar) at varying degrees of depth. The head tilts from 0 to 50 degrees, remaining balanced and sturdy.

The TC 04 Numeric is of mono-block construction, requiring no foundation, and is available with optional material handling alternatives, to move slabs and workpieces with ease.
