What is the cutting action of a bandsaw?
When the saw is set up for a cut, the operator raises the saw, positions the material to be cut underneath the blade, and then turns on the saw. The blade slowly descends into the material, cutting it as the band blade moves. When the cut is complete, a switch is tripped and the saw automatically turns off.

What is a common cause of accidents with the band saw?
Infections from ingestion of fresh, unpasteurized goat’s cheese or untreated milk are the cause of nearly a half-million cases worldwide each year. Evidence suggests that in the meatpacking industry, occupational exposure to powered saws is closely associated with amputation injuries to the hand and fingers.
Does a bandsaw have kickback?
There’s essentially no risk of kickback, however, as the motion of the blade tends to drive the work-piece against the worktable.
Why is a bandsaw called a bandsaw?
The bandsaw, although widely considered French in origin, was invented by the Englishman, William Newberry. In 1808, Newberry patented “a machine for sawing wood, in which an endless band or ribbon saw, strung over two wheels, was used”.
How important is a band saw?
That being said, a quality band saw will do a lot more than just cut curves. They are great for cutting tenons and some smaller rabbets, for ripping small pieces of stock, and for resawing thin strips from larger pieces of wood.
Where is the safest place to stand when operating a band saw?
Keep upper and lower doors closed and all guards in place. Cutting cylindrical or irregular stock on the band saw may be done only with a special jig, such as a V-block (special setup). Never stand or allow others to stand to the right of the band saw when it is running.
Is a bandsaw safe?

What causes a bandsaw blade to break?
Machine Defects 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.
What are the causes of breaking of hacksaw blade?
Sudden failure of saw blades, due to breakage of teeth (carbide) or breakage of the saw blade itself (HSS) is generally caused by:
- Too many teeth on the saw blade for the application.
- Excessive feed rate.
- Material movement caused by clamping problems.
- Incorrect choice of cutting parameters for the application.
Are bandsaws safe?
Which type of blades are better for curve cutting on a bandsaw?
For cutting tight curves (less than 5⁄ 8 ” radius) and delicate, thin materials, use a 1⁄ 8 ” or 3⁄ 16 ” 10–14-tpi standard-tooth blade. To cut curves greater than 5⁄ 8 ” radius, or when cut quality matters more than speed, use a 1⁄ 4 ” 6-tpi standard- or skip-tooth blade.

What are the dangers of using a band saw?
Contact with a blade can quickly lead to lacerations, and amputation. This hazard is especially significant on band saws due to how close an operator hands come to the blade during some operations.
