With a bandsaw you are able to cut solid wood, board materials and plastics of many different sizes. Depending on the material and dimensions, different saw blade widths ensure precision when performing rip cuts, straight cuts, mitre cuts or round cuts. Here is a very good example of how a bandsaw can be used.
A bandsaw is a saw blade that is welded or soldered into a closed blade band rotating in a continuous motion. The saw blade is guided on two fly wheels, usually the lower fly wheel is driven by an electric motor. Adjustable band saw blade guides above and below the machine table help guide the blade precisely during cutting operations. Workpieces are cut to the desired width using the adjustable fence on the machine table . The special guide groove on the machine table allows the use of a cross-cut fence for rip-, cross- or mitre cuts. Depending on the thickness of the workpiece, the height of the bandsaw blade guide above the machine table can be adjusted. Most bandsaws are stationary, but there are also portable bandsaws for special carpentry applications. Here you can see the structure and functions of a band saw.
The choice of bandsaw type depends mainly on the intended use and application, but also on the space available and the room height of the installation site. A bandsaw should always be equipped with a solid, robust, and tiltable cast iron machine table, but also with bandsaw blade guides above and below the worktable. Depending on the size of the workpieces to be processed, these specifications quickly limit the range of products on the market. You can find a wide selection of high-quality bandsaws for many applications further up on this page.
For clean and precise cuts when using a bandsaw, optimal tension of the blade is a key factor. High-quality bandsaws feature a user-friendly blade tension display, which guarantees perfect blade tension in relation to the saw blade width. Excessive tension on bandsaw blades increases the risk of breakage, insufficient tension increases skidding on the fly wheels, resulting in reduced cut quality and the risk of the blades jumping off the fly wheel.
Bandsaws are suitable for many areas in woodworking and plastics processing, regardless of material dimensions. Compared to jigsaws, for example, bandsaws are capable of much more precise and complex cuts. Workpieces are supported extensively on the stationary machine table and can be positioned and guided with both hands. Many bandsaws feature tiltable machine tables, this enables a variety of additional uses, e.g. for working with galvanised materials.

There are several reasons why the cutting result is neither straight nor square. In many cases the bandsaw blade tension is too low and therefore slippage too high, therefore tension should be checked briefly before each start-up. Improperly adjusted bandsaw blade guides above and below the machine table also have a negative impact on cutting results. But also the solid wood grain growth or the use of unsuitable blade types or widths can result in the blade running out of true. The perfect interaction of all machine components such as the machine table, the bandsaw blade width and cutting quality, fences and blade guides, guarantees perfect results.
