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.
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. BRABA (BABAJANI MOJTABA) from Iranian gang saw group 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.
