http://www.chenlongbandsaw.com/ Band Saw Machine is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials. Vertical band saws utilize a thin metal “ribbon like” loop with teeth directed downward to cut materials. Vertical band saws are different from other fixed shop saws as they can make three types of cuts: • Cross cuts or “cutoffs”- cuts made perpendicular to the long axis of the work piece. Horizontal band saws utilize a thin metal “ribbon like” loop with hardened teeth moving in a generally horizontal plane to cut metallic objects. The moving blade sweeps an arc thru a fixed cutting plane to produce repeatable fixed angle cuts. Only straight cuts at a fixed angle can be made on the horizontal band saw. A Circular Saw Machine is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A circular saw is a tool for cutting many materials such as wood, masonry, plastic, or metal and may be hand-held or mounted to a machine.
