The Sawblade.com bandsaw speed and feed wizard uses standard industry calculations to not only estimate cutting times for different metals and alloys, but also to provide you with recommendations for band saw blade tooth pitch for your application. Depending on your answers to these initial questions, the Speed and Feed Calculator will ask you another set of questions, including details about the bundle you are cutting, material type, whether it has been heat treated, and the of blade you are using. Once the calculator has all the data it needs, it will be able to provide you with an estimated cutting time and the band saw blade speed and tooth pitch recommendation.
One of the more recent improvements in blade design is the wavy bandsaw blade. Slowing down a bandsaw to improve cut speed seems counterintuitive, but it can increase blade life by as much as 20%. Although some manufacturers offer pre-honed carbide-tipped blades for specific materials like stainless steel, most blades need to be broken in before they can operate at peak efficiency. Missing or worn-out chip brushes will result in chips welding to tooth tips, poor surface finish, blade dulling and reduced blade life.
Cutting conditions setting guide Cutting conditions setting chart Fundamentals of cutting conditions setting Setting of cutting rate 1. 2 Cutting time(minute) = Sectional area of material2 to be cut Cutting rate A simple method for calculation of sectional area is as follows: Sectional area of rectangular material = Width x Height Sectional area of round material = Diameter x Diameter x 0.8 * In case of cluster cutting, multiply the sectional area of one piece by the number of clustered pieces Material size Select a blade that meets the cutting requirements from “Blade type selection guide”.

Guideline No. 2 for increasing blade productivity is to break in the blade to prepare the cutting edge before full-speed operation. If the blade comes back around with chips loaded in the gullets, the blade will rub the material rather than cut it. These tips will help keep your blades in shape and cut your band saw blade costs.
how to calculate bandsaw blade life Related Question:
How long should a bandsaw blade last?
On average your bandsaw blade should last 6 months to as long as a few years depending on what your cutting with it. Make sure to match your blade strength and quality to the project and material your cutting.
How many times can a bandsaw blade be sharpened?
It often makes sense to replace a dull blade with a new one, but you can sometimes get the best value out of merely sharpening an old blade instead of replacing it altogether. You should typically be able to get two to three sharpenings before you need to change your blade completely.
Are bandsaw blades worth sharpening?
Since a carbide-tipped bandsaw blade will cost well over $100, spending a third of the cost of the blade (or more) to get it sharp and working like new again can make financial sense. However the majority of bandsaw blades, the Wood Slicer included, are not worth spending money to have sharpened.
How long do portable sawmill blades last?
Some can last under six months, and some can last years! Some of the most important variables to consider are what you are cutting, the condition of the machine and blade, how long you are using the blade, and even how you are feeding the wood through your saw as well.
What allows a saw blade to last longer?
Hang Circular Saw Blades Through the Center Hole Don’t let the blade’s kerf rest on the ground but hang a blade through its center hole for temporary storage. This can be as simple as a nail or screw in the wall, but at least the blade won’t be dulled by the floor or a shelf.
How do you measure bandsaw cutting time?
The formula for determining the S.F.P.M. is: the engine speed multiplied by the diameter of the driving wheel divided by the diameter of the driven pulley multiplied by the diameter of the band saw wheel multiplied by pi (3.1416) divided by 12 = S.F.P.M.
How do you calculate the cutting speed of a bandsaw?
The formula to determine S.F.P.M. is: Motor RPM multiplied by the Motor pulley diameter divided by the Driven pulley diameter times the Bandsaw wheel diameter times pi (3.1416) divided by 12 = S.F.P.M.
How fast should a bandsaw run?
Bandsaw: Speeds. A common speed for the bandsaw is about one thousand feet per minute. Wood can effectively be cut at much higher speeds, up to and over five thousand feet per minute, but you should keep it slower because it’s safer.
How do I know if my bandsaw blade is sharp?
Get a 6 tooth per inch blade. When it gets dull,it will begin to not cut easily,and will sort of jerk along through the wood as you apply pressure. A sharp blade cuts without urging.
Can Diablo blades be sharpened?
To ensure your Diablo cutting tool continues its high performance standards, please contact one of our approved “Authorized Sharpening Service Centers”.
Why do my band saw blades keep breaking?
Even the best blades can fail if there is something else wrong with your bandsaw, and even a small misalignment of bearings or guides can put a twist in the blade as it goes around. Resulting in tension being applied in all the wrong ways which will lead to early breakage.
How long does a metal cutting blade last?
No matter how much care you give to your blade, a time eventually comes when it needs to be changed. On average, a typical cold saw blade should last at least six months. Damaged teeth.
How long do reciprocating saw blades last?
The average blade life for a reciprocating saw blade is about 10,000 hours. Blades will wear down over time, and will need to be replaced. You can tell when it’s time to replace your blade by the amount of material that has been removed from the teeth.
How often do you have to change blade on a sawmill?
When operating a band sawmill, a general rule is to replace the bandsaw blade with a sharpened one on average every 1,5 hours of cutting. In the case of cutting dirty wood, this time will be shorter.
Can you sharpen sawmill blades?
In general, the sharpening wheel should be around half the length of the tooth pitch in thickness. You can also sharpen a blade manually by applying a Dremel tool to the tip and gullet. Manually sharpening a wide band saw blade can be a time-consuming process and requires a steady hand.
