In addition to new machines, equipment and tooling, manufacturers around the world are also making improvements to existing product lines. Again, these developments are being made with an eye on increased pro-ductivity in the fabrication shop.
The following is a roundup of some of the more recent developments for stone fabricators.
Marmoelettromeccanica USA/Regent Stone Products of Virginia Beach, VA, introduced its newest line of bridge saw equipment, such as the Dynamica, which is equipped with the most accurate guide system available. The high-quality linear slide with roller and ball bearing system is equipped on all axes (X, Y and Z). This new system guarantees precision, vibration-free cuts, increased blade life and reduced maintenance, the company reports. The design of this saw allows it to have a smaller footprint, reducing the space required in the shop while still allowing it to cut full-size slabs - due to a rotating enlarged bed and rotating head that can cut in multiple directions. The twin beam bridge structure optimizes the speed and accuracy of the saw.

Terzago Macchine of Italy has upgraded its line of bridge sawing machines, produced in its Italian facilities. The newest version is the Omega, which has a blade capacity of 850 mm. The machine now is offered with some useful options, such as a head for tooling (electomandrel), brushless motors and computer numerical control. All these options change this automatic saw into a fully equipped milling machine. Terzago designed these features to allow for the production of countertops, vanities or other worked items with improved production.

Pedrini has introduced the M940 CN bridge saw. The cast-iron bridge and shoulders constitute an extremely rigid assembly withstanding, without any deformation to trolley weight and cutting stress as well as allowing for the use of fixed covers for the protection of transversal sliding guides all along their entire length, the company reports.
The coupling surfaces for the shoulders and the housings for rack, guide rods and synchronization shaft have been machined directly into the bridge structure.
The large diameter, hardened, ground and chrome-plated guide rods, are fastened along the two distant bridge edges.
The pinion/rack couplings guarantee movement precision of the bridge, while the compensation elastic devices assure the perfect operation of the disk when carrying out slow lateral travel of "spatula" cutting.
Spindle supports, tilting slide, main slide and saddle - with relevant guides and motors - form the powerful assembly of the tool holder trolley. The trolley allows the "step cutting" with up to 90 degrees tool tilting. The electrical panel protected in the accordance to IP54 is equipped with an air-conditioning unit, which maintains a safe internal temperature.
The control panel mounted in a convenient and safe position on a revolving support, comprises the industrial PC. The machine is operable both with the automatic cycles supplied as accessories and with externally obtained ISO code programs (for example from CAD-CAM), transferable from floppy disk or through local net connections.
Proper software will enable carrying out curved trajectories on XYZ triad, by splitting them into interpolated linear sections.
Through the "Touch-Screen" or DXF files (AutoCAD), it is possible to insert the drawing of the shapes to be carried out.

Alpha Professional ToolsR of Wyckoff, NJ, introduces the AWS-110, Alpha Wet Circular Saw, the most powerful saw in its class. Designed for use by the stone, tile and glass trades for cutting perfectly straight edges, this saw accepts blades up to 4 1/2 inches and has a 20mm arbor.
The AWS-110 features an in-line GFCI and double insulated wiring for safety. The 11.2-amp, 1200-watt motor is powerful enough to easily cut through various hard materials. It weighs only 6.8 pounds with an arbor speed of 13,000 RPM. The built-in water feed system eliminates harmful dust particles common with dry cutting applications and increases the longevity of the blade. The AWS-110 also features a reversible guide which can be used in one of two ways. With the face down, the guide can run along the edge of the stone; with the face up, it can be used in conjunction with a straight edge. The saw can also be used free hand.
In addition, the AWS-110 will accept the carriage assembly designed for use with the Alpha Guide Rail System. By attaching this carriage assembly, the AWS-110 is capable of cutting straight and true with minimal effort. Afterwards, one can easily transition to the polishing phase by attaching the Alpha Edgecrafter to the guide rail system.
Manufactured with the highest quality parts and workmanship, the AWS-110 is competitively priced.

The Blue Ripper stone rail saw is available from Granite City Tool Co. This saw was fully manufactured in the U.S. for optimum performance. This portable rail saw is designed for cutting stone slabs in fabrication shops, or on-site locations. It has a 2-hp, 15-amp, 110-volt Lesson induction motor and takes a 14-inch blade. This saw uses an 8-inch stainless steel flange to hold the blade into place, which provides blade stability and prevents flexing when taking deep cut plunges into the stone. The 8-inch flange also reduces noise. Using a 14-inch blade increases the average speed of cut to 9 1/2 feet per minute, according to the company.
The Blue Ripper rail saw was designed for simple operation. Because the blade cuts right next to the rail, set-up is easy. The direction of the cut is counter-clockwise, which allows for faster gliding and reduced chipping, according to Granite City Tool.
The weight of the saw is 79 pounds, making it possible for one person to lift and move. The reduced weight also minimizes risk of cracking narrow or thin pieces of stone.
Standard items included with 110-V saw are a 25-foot industrial cord and GFCI; a drip-proof Lesson true 15-amp 2-hp motor; standard 3/4 quick disconnect water fittings with a 25-foot hose; and 12 feet of aluminum-anodized rail with quick disconnect at 6 feet.
Saws with a true 220-volt, single-phase, 15-amp, 3-hp motor are also available. Continuous length and stainless steel rails are available up to 24 feet. One-piece lengths over 6 feet are not anodized and will require truck freight.
This new rail saw is available exclusively through Granite City Tool Co. of St. Cloud, MN, and Barre, VT; Euro Asia of West Palm Beach, FL; and Omega Diamond of Loomis, CA.
