What is Gang Saw and Frame-saw? What is the difference?

There are two kinds of machine called Gangsaw, one is frame-saw, use gangsaw blades with its gangsaw segments to cut, the other one is big gangsaw, use abrasive slurry and steel bits to cut. Usually frame-saw is commonly called gang saw, but another kind of big stone cutting machine is called gang saw too. Both of them are made in Italy mostly, Italy quality is always trustiness. Please see the photos of two kinds gangsaw at the bottom.

Frame-saw and Gang saw are used for cutting stone block, like granite and marble. It can also cut through thick concrete and slabs of other quarried blocks of stone such as soft stone limestone, or travertine into desired sizes.

Frame-saw is composed of diamond segments, or small bits of diamonds that are embedded onto the edges of gangs saw blades. Here, in order to assist in the cutting of stone blades, water is used as an abrasive medium to help cooling down the blade instead of steel bits. As the gangs saws blades cut through the blocks of stone, the gang saw that is used may not cut into a straight path because of its abrasive action causes vibration to the gang saw. As a result, the stone slabs that are cut using these types of gangs saws blades differ in thickness within one stone slab. These types of gangs saws blades are economically used for granite cutting, or to cut any other hard stone that does not require even sawing finish. The purchase of diamond gangs saw blades cost more, but produces quicker sawing action.  This type of gangsaw(frame-saw) is normally used for marble and concrete cutting, which is popular in developed countries and the area  abound with marble.

BIG GANGSAW is another type of gangs saws, which is used for cutting stone blocks by using a form of solution called abrasive slurry. The working units are abrasive slurry and steel bits. The abrasive slurry contains tiny steel grits that are injected on the surface where the cutting is to take place. these steel bits that creat friction when it makes contact with the surface that is to be cut, and assists in ensuring that the blocks to be cut are trimmed evenly. The steel bits eventually lose its abrasiveness as it is applied its strength to the gangs saws blades. When this happens, more abrasive slurry is added along with the old portions of abrasive slurry. Careful attention must be placed when adding abrasive slurry: too much or too little slurry may lead to uneven cuts on the stone’s surface, then the cutting result won't be satisfactory. This type of blade is normally used for granite and limestone cutting. The abrasive process used by these gangs saws blades are cheaper than other type of blades; however, it takes more time in block sawing. Most of Chinese granite factory use this kind Gangsaw to cut the slabs.



Gang saw blades(Frame saw) and its diamond segments, steel bits can be customized by professional diamond tools manufactureres, so that your gang saw produces a better stone slabs with good action. ChinShine has been occupied in researching and manufactureing of diamond diamond segments according different hardness of stone and cutting materials, different formula will be designed accordingly. By providing information on the surface that you will be cutting on, the size and type of steel gang saw blade you wish to use and the length, spacing and width of the segments, we can customize made to order gang saws blades for you. Even steel blades that you currently own can be embedded with these gangsaw segments, so that you can gain better cutting efficiency.

You should pay more attention to the following items.
1. Be careful during the gang saw working, if abnormal condition happens like vibration, noise or lose material on the cutting face, the equipment must be stopped and adjusted, keep it sharp.
2. To avoid momentary hot or cold, changing the customary angle from the gang saw blade is forbidden.
