Bandsaw Newbie-Refresher Course

A preventive safety course for bandsaw operators new to the machines as well as for those quite familiar with them. All bandsaw operators should possess adequate knowledge of mechanics, materials, and most important — safety — prior to any cutting procedure. Lack of experience combined with lack of knowledge will jeopardize not only the materials but the machine and worse, the machine operator. Every bandsaw machine offers various operating features, and before using any particular machine, it is important to be familiar and possess a minimum of confidence prior to operating. Aside from possessing thirty+ years of experience in a variety of shops and …

Feed and Speed Rate Factors

Running saw blades at the correct feed and speed rates is important if the goal is to achieve desirable output. There is an optimum balance between blade speed and feed rate for every saw blade and every material to be cut. Proper adjustment of feed and speed rates will help to maximized blade life and assure a satisfactory cut. Feed rate is determined by the bandsaw, material size and shape, guide spacing, cutting fluid, and tooth size and shape. The greater the blade speed, the greater the feed rate — up to the limits imposed by the above-mentioned production factors. Blade Speed Bandsaw …

Tube Cutting

Cutting tube is more difficult than sawing solid bars. The bandsaw blade is performing two types of cut, sawing solid as it enters the material then entering the hollow tube. The blade is now cutting two thin solids with a space in between — an interrupted cut. To achieve the best result in cutting tube, blade variables and bandsaw settings have to be carefully selected. Tooth pitch (TPI) is an important variable as well. The number of teeth engaged with the material determines both blade performance and durability. A few teeth in contact with the material can lead to stripped teeth, bending, or premature …
