The bridge saw is the most basic piece of equipment in a fabricators shop. However, the needs of fabricators vary greatly when considering a bridge saw, depending on the market they serve and their production requirements. For this reason CMS has designed a wide range of sawing solutions. From the basic Flexa Saw, an extremely robust semi-automatic bridge saw to the SPRINT / FALCON CNC saw which are fully automated, to water jet / saw combination such as SprintJet.
ABWQ-3000A granite bridge saw machine is developed from ABWQ-3000 bridge saw. The main difference is in the table. Pop up rollers are used in the table of ABWQ-3000A. So the operator can easily move the slab on the table before or after stone cutting.
ABWQ-3000A overall dimension is much smaller than heavy duty bridge saws, because stone fabrication shops usually don’t have enough space to stand a huge heavy duty bridge saw. The compact but strong structure design has greatly reduced manufacture cost. This makes the small bridge saw affordable for most of stone fabricators.
The manual bridge saw is the entry-level bridge saw for standard stone shops. This saw is powered and moved using joysticks. Laser positioning lines are standard, also a small programmable cutting system. Tables rotate manually with hard stops every 22.5 degrees. Horsepower ranges from 20 – 40 hp, blade size diameter between 14 inches to 48 inches.
Concrete polishing is not a new concept. Machines and technology that are used today for polishing concrete were originally made to polish stone and marble. It's only recently been discovered by the manufacturers of these tools that the same concepts can be used to polish concrete.
Why would one want to polish a concrete floor or anything concrete? Concrete is a very stable and sturdy material to make floors from. With the ability now to polish concrete and wax it making it shine just like marble, showroom floors that used to be dull and lifeless now take on a new quality of their own. Especially useful in car showrooms, concrete is easier to clean that stone or marble and with the polishing can look just as good as stone or marble.
Polishers work basically the same way on concrete as they do on stone or marble. The effect that the polishing tools have on the surface varies with weight, rotation of the tool and speed of the tool, as well as the polishing pad being used. Things such as cleaning between grit, density, direction of rotation and the speed at which the operator moves the machine also change the effect of the polisher on the concrete.
The final finish of a concrete floor will depend on the mix of gravel, sand, water and concrete in the mix. But for the most part, concrete surfaces can take on the luxurious glow of marble or granite, just at a lower cost.
Buffers and polishers for concrete surfaces are the same as those used for marble or stone or granite. Some concrete floors require a different grade of pads to polish and buff the surface, but the bridge saw machine is the very same one as used for other fine stone, marble or granite surfaces.
Bridge saw machine is mainly used for cutting and processing marble and granite slabs.For it’s one-piece structure，it has several advantages,such as small size,convenient to transit,install and adjust,high precision,also easy to operate.What’s more,it saves time and cost to build concrete cement base，especially suitable for customers in small plant and always work with moving plant.

Getting granite countertops installed in your home is a relatively simple process when looked at from the perspective of what you as the consumer can see from beginning to end. Simply put, you call us, select your slabs, & agree on the particulars, then a couple of weeks later they are installed.
There is however a lengthy process involved in getting the stone from its natural state in the earth all the way to your kitchen countertop. The process of turning stone into decorative and functional building materials has been more or less the same for centuries. On the other hand, the equipment has changed dramatically in that time, and the production time greatly reduced.
The process starts at the stone quarry where large blocks are cut from the earth often in a stair-step like pattern. Various types of sawing & cutting methods are used. There are wire saws which are long steel cables with diamond sections embedded in them. These cables are passed through "core holes" which have been drilled horizontally and vertically to a meeting point in the invisible corner of the "bench" to be removed. Then the cable is run through a drive, continuously going deeper into the stone. Core drilling, as mentioned above, coupled with "blasting" is another method of freeing large blocks of stone in this first step of the process. Some quarries use expanding liquid rather than explosives in the core holes-this is for the more fragile stone to keep from fracturing the blocks.
This first step of the process requires very large and heavy equipment to get the granite blocks from the earth and ready for shipping to the "gang" saws. When the blocks arrive at the gang saw operation, the entire block is cut into some 40-60 slabs simultaneously. These blocks are not a standard size, however a rough average would be 6 feet by 6 feet by 10 feet. This would yield 72 one inch thick slabs less the cutting blades, so around 60 slabs. The blades on a typical gang saw are not really blades, they are flat steel material 3" x 3/16 inch thick. They have no teeth or diamond in them. They are mounted on a large rack 2cm or 3 cm apart depending on the desired slab thickness. The rack is wider than the 6 foot wide slab. This rack in turn is mounted to an arm that is attached to the outer side of a massive flywheel creating a back and forth motion of the rack as the wheel is turned by powerful motors.
Once the block has been turned into slabs, the cart holding the 60 slabs is driven on its rail cart to the polishing line. The polishing line is another massive machine with multiple heads driving various grits of grinding and polishing wheels progressing from rough to polish. These heads drive horizontal grinders as the rough slab goes on a horizontal plane slowly through the machine on a conveyor belt. When the slabs come out the other end of the polishing line, they have become polished from their rough state. They are then loaded onto A frames for shipping to the wholesale warehouses throughout the world.
At this point the slabs enter our world here at Alpha StoneWorks, and our turn in the process begins. We come to your home and make an accurate template of your countertop areas. This can easily be done on new cabinets or on top of your existing countertops without disturbing them. After we have made the template, we like to meet with you at our shop for a layout review so we can agree on which portion of the various slabs will go on the different sections of your counters.
Once we have agreed on the layout, we go to word cutting and polishing your countertops. The surface has already been polished or honed, or brushed as the case may be. We cut the counters to match the templates on what is known as a bridge saw machine. This is a large "upside down" table saw. The sawing motor with the diamond blade are suspended above the saw table on the "bridge". This bridge in turn is sitting on two rails some 18 feet apart with rack and pinion drive to move the entire bridge east and west. The motor with blade runs north and south on the bridge via another set of rack and pinion gears. This entire apparatus allows the blade to be positioned anywhere over the 6 foot by 12 foot slab of granite. The saw motor only moves in one straight line, so the table beneath that the slab is laying on rotates in order to allow cuts at any angle needed. The rotating table has positive lock stops at 90, 45 and 135 degrees, and can be locked in any other degree for other cuts as needed. The table on our saw tilts up to nearly vertical via hydraulic cylinders. This makes loading easy and safe for both our workers and for your material. Once the countertop pieces have been cut to size, the edge polishing process begins.
Depending on the configuration of the piece and the desired edge detail, we have several different methods of shaping and polishing them. If they are straight line edges with a flat, beveled, or bull nose shape, they go one our "Pro Edge" machine. This is a machine some 18 feet long, 6 feet wide and around 6 feet tall. It is massively heavy and does the work of two to three men in terms of its output capabilities. You will see both the bridge saw and the Pro Edge in action in the video. If the edges are curved or have jogs in them, these are shaped with routers and grinders. Ogee edge details and other complex shapes of edges are done with large routers.
All through the process we have water spraying on the diamond tooling doing the cutting and grinding. Once the cutting and grinding is done, we proceed with the polishing process. This is done with a series of polishing pads on hand polishing grinders. There are 4 to 8 steps involved in the polishing process depending on the stone type and finish desired. The polishing grits start around 50 grit and go up to 8000 or 10,000 grit. In the case of antique finishes, stiff brushes are used on the grinding machines in place of the polishing pads.
Now that we have your countertops fabricated, it is time to bring them into your home and install them in place. This requires a little brute force and a little experience doesn't hurt a thing! We have learned to work smarter, not necessarily harder, to get the pieces into place. Granite countertops are very heavy to bring in. We use a combination of wheels, ramps, tables and other devices depending on the particular job. The slabs are test fitted then we adhere them to the cabinet tops with the appropriate stone adhesives. Joints are put together with epoxies formulated for stone work. Once the epoxy cures, we dress up the joints and other final details, leaving you with new gleaming granite countertops!
Wire sawing was first used by hunters and those living in the outskirts of the city as a survivalist gear to cut off branches in order to clear pathways. In the past, wire sawing is done by just a simple wire that is rotated manually by the person to cut wood or branches. Today, it has been developed as an indispensable method to cut and shape a number of things from crystals to steel; it is used by all industries. Through years of research and development, the wire saw has also been developed from just a wire into an intricate power machine that is composed of hydraulic motors and wires beaded with diamonds to cut through steel and other sturdy construction materials.
Through the years, wire sawing has been used by all industries as an established method of cutting various materials. It is heavily used in the construction industry, walls, dams, bridges, road and highway construction, docks and marine construction rely heavily on the use of wire saws to be successful. This type requires a diamond beaded wire that is powered by hydraulic motors. Using advanced tools such as the diamond beaded wire saw can help speed the process of cutting down steel or heavy stone block during construction or demolition. Construction industry has even developed the use of this type underwater during construction of bridges, retrofitting of pipes and wharf and pier revision.
Although it is commonly used for heavy civil construction, it is also used by other industries for precision and speed cutting. It is used in the semiconductor industry to cut silicon wafers for semiconductors. Gem makers and miners also rely on wire saws to cut and shape gems, minerals and other precious stone with precision. This type of wire saw that built solely for the purpose of cutting and shaping gems are also used in the glass industry to shape and cut stained glass to various shapes and sizes.
The use of bridge saw machine or wire sawing is more preferable to the use of blades in several occasions. The above mentioned industries for example prefer using wire saws to blades for various reasons. It produce less dust or other reputed companies have the technology to use them without producing dust during the cutting compared to the use of blade which produce a lot of dust when used. In the cutting of gems, they are more preferable because they produce less wasted materials compared to blades that have a lot of wasted materials.
Granite beautiful, durable, very hard. In ancient times, if there is mining, processing equipment and technology, it is certainly more popular than marble.
Granite because often contain other minerals such as hornblende, and mica, and present a variety of colors, including: brown, green, red and black and so common. Because it is the crystallization process is very slow, it's like a Rubik's cube crystal intertwined as one, so it is very hard. It is the same house as durable, can not afford debris, easy to scratch, not afraid of high temperatures. Regardless of color or light, as long as there is some common sense conservation, will not fade or darken. He almost free from contamination, high gloss polished surface, bringing a variety of weather almost all impurities not adhere.
Mining granite general use rope sawing. The emergence of new technology-intensive row eye and flame spray method. Flame spray method mined stones kerf neat, not born invisible injury, high production efficiency. Picked stones called after crude whole blocks, and then hit a wedge or artificial drilling and bridge saw machine, material specifications to obtain the desired block size, the plate; stone with milling machine or lathe machining, becoming cylindrical or arc; finally cut chisel artificial coarse and fine rock-like pattern, or by machine grinding, polishing, the surface of the crystal bright. Granite does not pollute the environment. Synthetic materials is often accompanied by bad or even toxic byproducts, period of use in the building needs to be replaced several times (each time back there handling problems). Granite without replacement, because it is very durable.
In addition, the granite is very practical, can be made into a variety of surfaces - polished, honed, fine grinding, fire, water knife handle and sandblasting. Because granite often containing radioactive material, the use of granite when the need to measure the radiation level, and then confirm it using the occasion.
