SECTION 6: METAL CUTTING

Workpiece

Inspection

Some metal workpieces are not safe to cut with a vertical metal cutting bandsaw; instead, a differ- ent tool or machine should be used.

Before cutting, inspect the material for any of the following conditions and take the neces- sary precautions:

•Small or Thin Workpieces: Small or thin workpieces are dangerous to cut if held by hand—avoid cutting these workpieces if possible. If you must cut a small or thin workpiece, attach it to or clamp it between larger scrap pieces that will both support the workpiece through the cut and keep your fin- gers away from the blade. Some thin sheet metals will not withstand the forces from this bandsaw during cutting; instead, use a shear, nibblers, or sheet metal nippers to cut these pieces.

•Round/Unstable Workpieces: Workpieces that cannot be properly supported or sta- blized without a vise should not be cut on a vertical metal-cutting bandsaw. Examples are chains, cables, round or oblong-shaped workpieces, workpieces with internal or built- in moving or rotating parts, etc.

•Material Hardness: Always factor in the hard- ness of the metal before cutting it. Hardened metals will take longer to cut, may require lubrication, and may require a different type of blade in order to efficiently cut them.

•Tanks, Cylinders, Containers, Valves, Etc: Cutting into containers that are pressur- ized or contain gasses or liquids can cause explosions, fires, caustic burns, or machine damage. Avoid cutting any of these types of containers unless you have verified that the container is empty and it can be properly sup- ported during a cut.

•Magnesium: Pure magnesium burns eas- ily. Cutting magnesium with a dull blade can create enough friction to ignite the small magnesium chips into a fire. Avoid cutting magnesium if possible.

Cutting Tips

•Keep the upper blade guide assembly adjust- ed to within 1⁄4" of the workpiece.

•Avoid overheating your blade. Keep an oil can nearby and squirt the blade near the cut- ting area when it gets hot or you see a small amount of smoke. Different metals require different types and amounts of lubrication.

•Replace, sharpen, and clean blades as nec- essary. Make adjustments periodically to keep the saw running in top condition.

•Use light and even pressure while cutting. Light contact with the blade makes it easier to follow lines and prevents extra friction.

•Avoid twisting the blade when cutting around tight corners. Allow the blade to saw around the corners.

•Misusing the saw or using incorrect tech- niques is unsafe and results in poor cuts. Remember—the blade does the cutting with the operator’s guidance.

•Never start a cut with the blade in contact with the workpiece, and do not start a cut on a sharp edge.

•Pay attention to the characteristics of the chips when cutting—they are good indicators of proper blade speed and feed rate. Page 38 shows the basic chip characteristics and what they mean.

•Use the right blade for the cutting task.
