Laguna LT18 3000 Series Bandsaw

Uses a blade consisting of a continuous band of metal with teeth along one edge to cut various workpieces. Bandsaws are used for woodworking, metalworking, or for cutting a variety of other materials, and are particularly useful for cutting irregular or curved shapes, but can also be used to produce straight cuts. The minimum radius of a curve that can be cut on a particular saw is determined by the width of the band and its kerf.

  • Blade Selection:
    • Blades differ in three ways: the width of the blade, the number of teeth, and what the teeth are made of (this usually being the least important factor if the blade you are choosing has the right width and number of teeth for what you are cutting).
    • The right blade will depend on the kind of material being cut (hard or soft wood, aluminum, plastic, steel, stainless steel, brass, etc), the thickness of the material (how many teeth per inch (TPI) you will need — as a general rule: more TPI are for thinner materials, harder materials, and where finish is most important, while fewer TPI are for thicker materials, softer materials, and where the speed of the cut is most important), and how tight the turns and curves you will need to cut into the material will be (the width of the blade, the radius of your cut).
    • For general usage, have 3 teeth in the material you are cutting.

Also note that wider blades resist shock and wobble less while cutting.

  • Machine Speed:
    • The Bandsaw has a Variable Frequency Drive, allowing you to ‘tune’ the speed of the bandsaw. As the major difference between a bandsaw for metal and wood is the speed of the blade, this allows our bandsaw to be used for both metal and wood, with a dial setting the speed.
    • For wood and aluminum, a fast cut is best. Turn the dial all the way up.
    • For plastic, medium speed is best, but will require some playing around — too slow a cutting speed will result in a rough edge where the blade passed due to the teeth actually chipping the material away. Too fast a cut will heat up the material and will cause the plastic to melt slightly.
    • For steel a slow speed is best. Running the bandsaw at too fast a rate will damage the blade.
  • Usage:
    • Make sure you have the right blade on the machine (if not, let a staff member know and they will change it), and that the right speed is dialed in.
    • If performing a straight cut, or a miter, measure your material against the guide rail.
    • Hold the material down firmly against the table, your hands on either side of the blade (but making sure your finger tips are away from it).
    • Work the material through the blade.
    • For curved cuts, feed the material into the blade and have the blade trace out the curve you are looking for. Do not force the material into the blade as this can damage the blade, the materials or you.
    • See the chart for minimum cutting radius to make sure you are able to get the curve you need with the blade you are using.
