gang saw

A head saw, framesaw, gang saw or head rig, is the saw that makes the initial cuts in a log at a sawmill, turning a log into cants, or planks of wood.

The original powered head saw was composed of long, narrow blades that used an up-and-down motion, a reciprocating saw. Each blade was set at a fixed width meaning each log was cut identically, regardless of flaws. This design was not energy efficient and around 1860 sawmills began to adopt the more efficient circular saw. In the 1870s,
the limitation of log size due to the radius of the circular saw was improved with the introduction of the double circular saw- with one blade atop the other. In the 1880s, the band saw was introduced and was able to allow the head saw to handle logs of nearly unlimited size, ideal for the Californian redwoods.

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.

Gang Saw,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.
