Band saws are not suitable for cutting very thin sheet metal; a rule of thumb suggests the metal to be cut should be thicker than the depth of 3 band saw blade teeth, however they are excellent for cutting thin walled profiles such as box and angle. Blades with a higher tpi provide a smoother cut edge whereas blades with a lower tpi make light work of cutting through thicker metal stock. For cuts using a cordless band saw; ensure the workpiece is secure, line up the blade to the intended cut line and lower the blade into the metal.
Keep hands away from the saw blade of the hacksawing machine or bandsawing machine when in operation. Since the diameter of the drive wheel of the bandsaw machine establishes a fixed ratio between the motor or transmission speed in RPM to the blade speed in FPM, it is not necessary to convert RPM into FPM as with most other machine tools. Bring the two ends of the blade together at the butt welder of the bandsawing machine and weld the blade into a continuous band as described in the pertinent operation manual for the machine.
Even an old band saw that has been properly operated and maintained can achieve a high-quality cut approaching that of a modern band saw. Your saw blade vendor can supply charts for materials, blade speeds, and cutting rates and has access to the blade manufacturer’s technical department for answers to specific questions. In most cases, crooked cuts can be traced back to improper saw operation such as too much downfeed pressure, too slow a blade speed, or the guide arms are too far away.
On a typical wood or metal cutting blade the hook or of point of the blade should be pointing down for a vertical blade bandsaw, or for a horizontal blade saw the hook of the teeth should be pointed such that they enter the workpiece first as the blade moves. During regular cutting on a well set up bandsaw the blade will move or bow backwards a bit as you press the workpiece into it. The side guides will assist in keeping the blade cutting straight, but they are not an iron lock on the blade forcing it to cut straight.
I wanted to experiment with cutting metal on my bandsaw, so I bought some metal cutting bandsaw blades. The problem is that metal cutting bandsaw blades need to run at less than a tenth of the speed of wood cutting blades. With metal cutting, the blade only lasts so long, so between the shorter life and lower speed, the metal cutting blade doesn’t have to bend and un-bend as much in its lifetime as wood cutting blade does.
how to use metal cutting band saw Related Question:
Can I put a metal cutting blade on my band saw?
Salem Straub. Typically if you run a metal blade on a wood bandsaw the excessive speed (2000 sfpm+) of the wood saw will knock the teeth off of your metal cutting blade in a hurry. You could make it work, but you would have to slow the blade drive wheel way down. Think 250 sfpm to 80 sfpm.
What speed should you cut metal with on a band saw?
To cut steel, you’ll need to run the machine at a much slower speed — about a hundred feet per minute. A machine running at this speed might look like it’s running too slowly, but running it any faster almost guarantees that you’ll damage the blade.
What is the difference between a wood and metal band saw?
A metal cutting bandsaw is typically built more solidly than a saw designed for cutting wood, so there are no issues with the machine itself. As for the blade, the wood fibers could clog the metal blade’s teeth more quickly, and the blade will probably cut through the wood more slowly.
Can a bandsaw cut hardened steel?
Carbide band saw blades provide high wear resistance and toughness when cutting a variety of applications such as: case hardened steels, spring steels, high speed steels, nickel based alloys, case hardened steels, composite graphite, high nickel alloys, titanium, inconnel, and other exotic metals.
What is a metal band saw used for?
A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and lumbering, but may cut a variety of materials.
Can you cut wood with a metal cutting blade?
You can use a metal blade to cut wood. A circular saw blade cut metal in a sluggish rotational speed of 25m/s. They are driven by a motor having high power and an A/C vector drive. They are long lasting and non-reusable.
How do you cut a bandsaw straight?
Blade is Installed Incorrectly Typical bandsaw blades can be flipped “inside out” to make the teeth point the other direction. On some knife edge style blades and grit edge blades you can get a fresh sharp cutting edge from a blade this way, just by flipping it inside out.
Which of the following should be worn when operating a metal cutting bandsaw?
Wear safety glasses when operating the metal cutting bandsaw. 2. Never wear loose clothing, or jewelry when operating the metal cutting bandsaw.
How much tension should a bandsaw blade be?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
How many teeth does a bandsaw blade have?
The general rule of thumb is: For wood and soft materials aim for 3 – 6 teeth in the workpiece. For metals and harder materials aim for 6 – 24 teeth in the workpiece.
What RPM should a bandsaw run at?
Bandsaws always use 1725 rpm. The 3450 rpm are way too fast. From contributor R: Depending on the size of the wheels bandsaw blade speeds can vary between 2000 SFPM to over 4500 SFPM.
Can you use a band saw to cut wood?
With the correct blade, a band saw can cut wood or metal, in either curves or straight lines. Blades come in a variety of widths and tooth counts. Narrower blades are good for tighter curves, while wider blades are better at straight cuts.
Can I cut wood with aluminum blade?
Aluminium is relatively soft as metals go, and by comparison many woods although softer are weirdly more wearing of cutting edges. Also, clearance angles are different so it’ll cut some wood or board materials well and others much more poorly but this is also true of some wood blades!
What can you do with band saw?
A band saw can be used to cut curves, even in thick lumber, such as in creating cabriole legs, to rip lumber and to crosscut short pieces. The most common use for the band saw, however, is in cutting irregular shapes. The second most common use is in resawing or ripping lumber into thinner slabs.
How do you cut spring steel?
Re: Need some help cutting spring tempered steel! Use a cutoff wheel in a mototool or die grinder and cool the metal every 4 to 5 seconds in water. The other way is don’t worry about the temper and re-heattreat it afterwards.
