Metal cutting bandsaws are an indispensable part of a fabrication workshop. It is a faster, more versatile tool than a powered hacksaw. But how do you select the right one?The first thing you should consider is the amount of power the machine will need. Depending on the materials you cut, you will need a different set of speed controls. You may also need to change the cooling system, depending on the material you are cutting.
One of the most important features of a metal cutting bandsaw is the blade. There are various materials that can be used, including alloyed steels, mild steel, and bi-metals.Some machines have a built-in blade welder. This feature allows an operator to quickly repair a broken blade without having to wait for a replacement.In addition to the aforementioned features, metal cutting bandsaws come with adjustable horizontal and vertical positions. Many machines also have a tension control device, which eliminates saw breakage caused by improper tension.
A blade that has too many teeth will strip rather than pull out chips. Teeth that are too coarse can cause heat buildup. To prevent this, you can use a high strength, heat resistant blade.Choosing the right blade depends on the amount of cutting you need to do. If you are unsure of what to look for, consult the manufacturer's catalog to find out what they recommend.Using a Vari-Raker tooth sequence can help provide a smooth, fast cut. This tooth pattern is also a good option for general metal cutting tasks.
