Factors that determine the proper band saw for the application
Material - different types of materials determine the kind of band saw that is necessary. For example, in cutting aluminum, a much higher blade speed will be required compared to other materials. Most band saws Canada are available with variable speed motors that can match the blade speed, blade type and material type to gain the best results. In some instances, the blade speed has to be adjusted to optimize blade life.
Shapes of material – different band saw blades in Canada can be applied in cutting shapes. For example, in cutting large I-beams, a true structural band saw will be required while cutting round stock that has to be fed into a chip machine. It needs a good dual column band saw to achieve the best cut. Aside from the single and dual column band saws, there is a vertical and scissor-style band saw available that will provide high levels of performance.
Blade and material sizing – these are some of the most important considerations in the choice for the band saw blades in Canada. It is very essential to properly size the dimension of the part or bundle to the blade. It is not suggested to max out the band saw’s capacity as well as that of its blade. As the material increases in size, the guide arms spread apart and the beam strength becomes critical which requires that the blade be sized to approximately 80% of the work. Beam strength tends to affect both the squareness of the cut and production rates. The length of the blade must also be considered since longer blades have more teeth and therefore lasts longer. Longer blades also have larger blade wheels that will put less stress on the blade because it wraps around the wheels.
Bundling – one of the techniques used in increasing production rates is to bundle cut. If you are considering this technique, make sure to use bundling clamps and to weld the ends of the rounded tubing to prevent the spinning of parts that quickly destroy the band saw blade. Another strategy that can improve production rates is to increase blade size and motor size so that they can pass through the materials more quickly.
The number one reason for the failure of band saws is the repeated shocks and impact that it is put through and not because of excessive use. Band saws are made to be durable and strong but one blade does not work well for all purposes. It is therefore important to have different kinds of blades for every application and they must be durable enough to withstand all forces that it might be put through.
