how to operate a horizontal band saw Related Question:
What is the use of horizontal band saw machine?
Generally the Horizontal saw is used to saw steel and other hard materials, while the Vertical Band saw is used for soft plastics, wood, and non-ferrous metal alloys. Always use the widest blade possible for the job being done. Blade guide must be set to just clear the top of the work piece.
How should you hold the stock while cutting it with a band saw?
Hold stock firmly and flat on the table to prevent the stock from turning and drawing your fingers against the blade. Use a push stick when you remove cut pieces from between the fence and saw blade or when your hands are close to the blade.
How many band saw teeth should contact the workpiece at once?
TPI is measured from gullet to gullet, not tooth tip to tooth tip – this is known as pitch. 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 should you do if the blade breaks while operating the band saw?
If blade breaks during operation immediately stop the saw, leave the stock where it is, unplug the saw and report the incident to the teacher.
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.
Can a band saw cut curves?
Whether it’s a tight curve or a closed opening, you can cut it on your band saw with a couple of easy tricks. Cutting on the band saw can be the same thing. The narrower the blade, the tighter the spots you can cut; in fact, some band saw blades rival a scroll saw for cutting tight curves.
When using a horizontal band saw you should adjust the blade guide as close to the work as possible?
The upper guide and guard should be set as close to the work as possible, at least within 1/4 inch. If the band breaks, immediately shut off the power and stand clear until the machine has stopped. Examine blade before installing to see if it is cracked, do not install a cracked blade.
Why is my horizontal band saw not cutting straight?
Make sure the blade is running in the correct direction. On machines powered by three phases power so it is common to get the wiring reversed and have the blade running the wrong direction. On all vertical blade bandsaws the working portion of the blade should go down. This forces the workpiece down into the table.
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.
What is the difference between power saw and horizontal band saw?
The horizontal band saw can cut the hardest metals but a vertical band saw can only cut pliable soft metals. The horizontal saws use a lot of power to cut hard metals while vertical saws only use less power.
What is the name of the part used in horizontal band saw?
The blade of the machine is held either by guide blocks or bearings. The saw blade is secured between two wheels or pulleys. One of the wheels called the driven wheel is fixed in place and it provides the power to the saw. The other wheel is the idler wheel which is used to make the blade in the saw tight or loose.
Which side of the line should you always make cuts on?
Always cut to the outside of your mark line because you will have to round off your edges regardless. For thinner wood, a jigsaw can provide better results.
How far should fingers be kept away from the blade of a band saw?
1. Set the saw guide to within 1/2 inch of the stock before turning on the power. 2. Do not put your fingers closer than two inches from the blade.
How can you tell if you are using too much pressure or twisting the blade excessively?
you feed the material too hard or twist the material too much, you will hear the saw slow down. This is a cue to ease back the pressure. Too much pressure or twisting can break the blade.
Which way should the teeth face on a bandsaw?
The teeth on the bandsaw blade should face down so that the cutting action is from the top of the material to the bottom.
