There are a wide range of automatic band saws to suit every application depending on the size of the bar or billet you wish to cut and the hardness of material you wish to process with bandsaws that have been designed for non ferrous material such as aluminium, brass, copper or other non ferrous material and band saws designed to cut ferrous material, such as normal steel and the harder stainless steel and nimonic steels.
The design of the automatic band saw will depend on the application with the most common band saws being of pivot design and the automatic feed system being a shuttle or vice feed mechanism or the more cost effective rocker feed automatic system.
With a vice feed or shuttle type automatic band saw the required component length is programmed into the machine and the rear vice moves to this programmed position and indexes the stock material forward to be cut. This will continue until the number of pieces programmed has been achieved or the band saw has run out of material.
With a roller feed automatic band saw the number of components is again programmed into the band saw and vertical powered rollers propel the bar through the band saw until it reaches the programmed length with the length being measured by an encoder in the powered feed rollers.
When cutting harder steel such as stainless or nimonic steel, or when cutting larger diameter steel, twin column automatic band saws are considered a more efficient and productive machine. These band saws are by design, more rigid and usually are fitted with a wider band saw blade to give higher performance and better blade life and usually are only supplied with the vice feed or shuttle feed automatic style of indexing the bar through the machine.
