Sometimes, when buying a new tool, certain doubts arise about the correct way to use it. It’s the same thing while purchasing a portable band saw.
Have you ever wanted to know what’s it, and how exactly it works? We have a brief guide on it for you then. To know more, continue reading.
What Is A Portable Band Saw?
As for the definition of this phrase, it is electric, pedal, or automatic saw that has a long, narrow, flexible and serrated metal band on one of its edges, that slides on two wheels with a space between them and that is in the vertical plane to said tape.
This type of saws can be used both in carpentry and in metallurgy and also for cutting different materials in other activities. It is often used to cut irregular shapes. One of its uses is for curved and complex ways of wood.
When cutting metal, saws are used that require a coolant that cools the blade. In this way, overheating is avoided, which could cause a defect in the cut and, above all, would reduce the life of the saw.
As for automatic band saws, it is a brand that is guided by a laser. They have a preset feeding speed. It also has reverse and clamping of the parts.
These types of saws are used in areas where one operator can handle multiple saws. Some also work through numerical control by a computer, which facilitates the precision of the cuts.
How to Use A Portable Bandsaw?
1. Read the Instructions of The Machine
Although many people skip this step, it is essential to read the manufacturer’s instructions and recommendations to know how to use a band saw correctly.
Follow all their instructions to the letter, set the tool to a working height that is comfortable for you (generally, above the waist), and make sure that you are going to work with sufficient lighting.
2. Choose the Appropriate Cutting Blade for The Job You Are Going to Do
To know how to use a bandsaw correctly, it is necessary to choose the correct width of the blade, its thickness, and the DPP (teeth per inch) based on the work that we are going to do.
The thinner, thinner blades have a smaller turning radius, allowing you to make more intricate curved cuts.
However, if you are going to work with not very sharp curves, the somewhat broader and thicker saws are more recommended, since they are more durable.
Compared to DPP, a blade with many teeth per inch results in a much smoother cut but will take longer to do than a blade with less DPP.
3. Adjust the Saw Blade
Important! From this step to the moment of cutting, the machine must be unplugged.
The blade needs to be adjusted so that it is taut enough so that it does not deviate from the cut but loose enough so that it does not become damaged.
You can check it by pressing the ends of the blade and applying several kilos of force. If it is tight, it will move about 3mm in this experiment.
4. Check the Alignment of The Saw Blade
First, open the cover to gain access to the adjustment wheels. Turn the upper wheel at least 15-20 turns and check that the blade does not deviate throughout the process. If it does, use the adjustment knob to set the blade in the correct position.
5. Check the Workplace and The Piece on Which to Cut
Confirm that the work area is adequate for the realization of the same and that you have enough space to rotate the material as many times as you need without a problem.
Also, you mustn’t forget to mark the piece that you are going to cut with a pencil or marker that is easy to distinguish.
Now plug in the machine and cut the material you want to work with, always keeping your fingers as far away from the blade as possible.
If you see that the sheet deviates from the cut or you notice some strange movement, stop and check the settings.
How to Keep Yourself Secure While Using A Bandsaw?
- Secure the machine tightly and to the bench or floor.
- Read the user manual and understand the characteristics of your particular machine.
- Wear safety glasses or face shield.
- Ensure that all the protections and guides are in place and well-fixed, never operate the saw with the wheels exposed, in this case, the blade may run or break and eject some of its pieces.
- Adjust the top guide 1/8 “above the material being cut.
- Ensure that the cutting belt is adjusted to the correct tension and that it runs correctly on the guide wheels.
- Hold the cut piece firmly, taking care to keep it flat on the table.
- Please keep your hands to the side of the sheet, not in line with it. Do not force the material on the sheet.
- Use a Fence and Push Stick to cut narrow pieces.
- Keep the ground clear of obstacles around the machine.
- Do not handle the cut piece until the tape stops completely.
- Use the right blade for every job, a narrow blade for cutting small radius curves, broad blade for cutting straight lines.
- Never leave the saw running unattended.
