The band saw is the circular saw used to cut a wide range of materials like meat, wood and metal. A blade with sharp edge teeth rotates in the circular motion in the fixed frame. The band saw blade is made of stainless steel, which comes in a variety to complete a majority of cutting works. It is generally used to cut large stocks in to smaller pieces. However, you need to take care of the beast to get better results.
The blade of the saw is the most important and delicate part of the machine. You need to take care of its tension, alignment, its rotating speed, teeth, and temperature. The blade can be made up of several materials. A heavy duty blade is made up of carbon and can last ten times more than a stainless steel blade. There are many ways to create circular saw
To have a perfect woodwork plan or even the metalwork plan, you need to create a circular saw experience. As a rookie in this field, controlling the band saw is not an easy task, especially the saw blade.
The blade never lasts forever. You should know how to change the blade and when to change the blade.
Old blade: The blade which you are using creates much friction even if it is the new brand. To keep it in good condition, you should change the blade with another one after a frequent time, which depends on the wood type. And again you can use that old blade after the certain time when the performance of the blade declines. Use them in a cycle. When cutting a metal, you generally need to pour water as a coolant on the blade to reduce the temperature of the blade. High temperature can lead to broken teeth or fully broken blade as it becomes more flexible.
Broken blade: A broken blade should be changed immediately for the long life of the saw and decreases the chances of any accident. If the blade breaks down, you should immediately switch off the saw and stand away until the saw has completely stopped revolving. If some teeth are missing, you need to change the blade. If the blade is not enough sharp, you should replace it with a new or should sharpen it manually.
For different purposes: When you need to cut soft wood like the soft pine. It I is better to choose a blade with fewer teeth that are the teeth number per inch (TPI). The cuts made by this blade will be rough but will give a great speed. In the other hand, when you want to handle any hardwood, you need to choose a blade that is a more suitable band saw blade and it needs to have more teeth number per inch, which will give you smoother and slower cuts.
It ultimately depends on what you are going to slice and which blade your saw appreciate with. You need to know the length of the blade in your saw as you will get it of several sizes in the market. When dealing with metals, you need a tougher blade with more teeth and while ripping the woods apart, you can get it less costly.
The blades used for cutting down metals are likely thinner and have more teeth per inch than wood cutting blades. You also need to check the requirements of your saw first. Use the appropriate size of the blade that can enter into your saw.
The band saw that you are using if is a speed regulating one like Dewalt DCS371B, you need to choose a blade with more teeth like 14 -18 TPI and it easily holds up the metal as well: steel and iron pipe. It can enhance or limit the speed of the blade and you are not required to change the blade especially for the material you are going to cut down.
The band saw takes in charge of having a single speed function, so it is vital to determine the speed of your saw. You need to buy the blade by checking the FPM (foot per minute) of your saw. For the greater speeds, you need to choose fewer TPI blades such as 3 – 6 TPI for SFPM 3000. If the operating speed of your saw is low, then go for the blades with more TPI. The normal cutting speed of the saw differs from 40 to 5000 feet per minute.
Your purpose: We cut a variety of material with a saw. It can be the meat or the iron pipe. This whole thing matters when choosing a blade for your saw. A tougher blade is required for iron cutting with a number of small teeth.
Choose the blade width: It differs from 1 to 3 inches. The blade width is determined by the stock cut and the blade that can fit into your saw.
There are some factors to be noticed daily to make your saw blade durable. You need to check them before getting started to work.
Pay attention to set up before use: The first thing to do when you approach the saw is to check its alignment and the moving parts of the saw. To increase the durability of the blade, you need to check its tension and sharpness every day and after every heavy duty work. The alignment of the blade is most important to check. With the wrong aligning, the blade can get off the path in the working condition and can cause a serious injury to the saw or the worker.
Check the tension of the blade: The tension of the blade means how tight or lose your blade is on the opposing wheels. The blade should be neither tight nor too lose. The extremely tight blade will exert more pressure on the bearings and can result in malfunctioning. The lose blade can get removed by slipping on the wheels. When you use the blade for a long time, it gets heated up and tensioned by contracting and relaxing subject caused in the solids. As a result, you need to slightly distension the blade.
Apply lubricant: You need to apply lubricant to the moving parts like bearings of the saw daily. It will decrease the friction and force on the blade, and increase the durability of the motor. The lubricants should be applied regularly to the most tensed parts of the saw like wheels. It will keep them free moving and will create less friction with the metal.
Speed and pressure: The speed of the saw also determines the durability. You should choose a right blade according to the single speed saw or you need to adjust it according to the material to be cut in the saw with more speed levels. The pressure should not be excessive on the stock you are cutting. It should be optimum for the blade at which it runs smooth and the motor does not change its noise much.
The right blade choice can save time for you. You need to get the blade with the requirement you have. If you are using a normal blade with less and bigger teeth to cut metal, the blade will break easily and you work will be interrupted.
For softwood: The blades with less tooth per inch can do their job perfect in cutting the soft wood. The width of the blade should be the maximum your saw allows as it will keep the cuts straight. The blade with skip tooth type should be preferred as they increase the cutting speed and do not clog with the softwood particles.
For hardwood: The blades used for hardwood should have more teeth than softwood blades as it is hard to cut, and more spacing will put more force on the blade and the motor. The hook type tooth blades should be used for this purpose as they have more deep spacing and 10 degree rake angle for better penetration.
For metals: The blade used to cut metals should have more teeth per inch than other blades. They need to be made up of strong metals like bi-metals or carbon. These usually require a running coolant on them to cool them down by the high temperature created by the friction with the metals. They are usually thinner than wood cutting blades.
The band saw blades are very delicate to use. You need a lot of practice to learn the skills to use the band saw effectively. Choosing a right blade for the band saw can be a challenging work for a very experienced carpenter too. The above listed basic tips are expected to assist you to choose a long- lasting blade. We wish that the information provided to you will guide you better. Have a nice and happy day.
