For a good owner, the presence of all necessarytechnology - this is happiness. It is especially important to have various adaptations to those people who live in their own home. For example, a self-made band saw will make it much easier to work with wooden products. At the same time, as it is already clear, the device can be built most from improvised materials.
In principle, the device is used in sawmills in industrial or domestic environments. It has certain advantages and disadvantages, but it is applied very widely.
The device of this unit is quite simple.On a stable frame mounted motor and pulleys. The cutting cloth joins them. Thanks to the engine operation of the device is provided. Depending on the type of canvas, you can cut not only wood, but also metals, alloys, polypropylene.
Tape saw do enough with their own handsquickly. Naturally, it is necessary to comply with all the requirements of the drawing and be precise. However, you should first decide whether to do it. To do this, be sure to consider all the pros and cons of the unit. So, among the advantages can be identified as follows:
- High level of performance.
- Low heat output.
- Excellent accuracy of work, as well as high speed.
- Ability to produce blanks for individual parameters. In this case, you can cut not only in a straight line, but also curved bends.
- For the manufacture and use of the tool you do not need a large amount of money.
- Band saw, which you can do with your own handsnot so difficult, leaves a cut a small width. Because of this, you get a minimum of waste. This is very important for the production of various wood products.
Naturally, band saw, do it yourselfwhich can be done in a few days, is not without flaws. For example, with such a device you can only make longitudinal cuts, as its design will not allow you to do something else. In the process, the machine can produce a strong noise and vibration. In addition, the device has a large size. If you decide to make such a machine yourself, then you will have to use special equipment.
If you are not afraid of flaws, then such a device can bring a lot of benefit to the owner.
The band saw can be made with your own handsfrom those materials that can be found at home. However, the canvas will have to buy. Before this is to decide exactly what it should be. To do this, you need to know what you are going to cut. So, there are such canvases:
1. Bimetallic. They are used for cutting sufficiently strong alloys, stainless steel. At the same time you can be sure that the tape will not burst.
2. Diamond. They are used if it is necessary to process marble, granite, quartz and other hardest materials.
3. Carbide. They can be used to cut such alloys, which are quite difficult to operate.
4. Made of tool steel. Such canvases are most often used at home or in small workshops. They are most suitable for working with simple materials.
Before you start making band saws, you should understand their types. There is such a classification of devices:
- Toothless.They have high performance and can work with metal. A feature of such devices is that they still have small teeth. They work due to friction and additional heating.
- Gear. They can be used to cut wood or plastic. A feature of the paintings in such devices is that they are closed.
- Electroiscus. Most often they are installed in large-scale industries where a large amount of material needs to be processed.
It should be noted that not all the construction can be built from improvised means. Therefore, before you make a band saw, you need to collect the necessary details:
1. Wooden boards, chipboard, MDF or plywood. From these materials, the frame and the bollard for the saw, as well as pulleys are made.
2. Sheet steel for the production of cutting blade or ready-made part, which can be purchased at the store.
3. Channel and steel bar. These parts are used for the manufacture of the support frame and the axis on which the pulleys will be mounted.
4. Sheet rubber. It is used to protect wood.
5. Durable belt that will ensure the rotation of the wheels on the machine.
6. Polyurethane adhesive for joining some parts.
7. Fasteners: screws, brackets, bolts, washers and rubber gaskets.
8. Sleeves.
9. Electric motor. You should not buy a very expensive model. Just decide what power the machine should have.
Thus, the tape can be constructedsaw with my own hands. Drawings of this design should be done as accurately as possible each step. Naturally all the schemes you can find already in finished form.
In order to start making a band saw with your own hands, you need to prepare. You need these tools:
- Welding machine.
- Cutting and grinding machine.
- Screwdriver.
- Bulgarian.
- Screwdrivers.
- Hammer.
Naturally, you may need other tools. For example, a milling machine.
Now we should proceed to the production of the presented unit. To do this, it is necessary to carry out several stages:
one.If you decide to make such a unit, like a band saw, with your own hands, you should already have drawings. They are the key to success. It is worth starting with the construction of the table and the bollard on which the mechanism will be fixed. To do this you will need a furniture board or wood.
2. Next, pulleys are made of plywood, which are subsequently glued with sheet rubber. Wooden elements must be sanded and coated with epoxy.
3Now you can make a frame to assemble the entire device. It may be C-shaped, which ensures good tape retention. The support frame is made of a channel on which the steel axis is put on.
4. Now we will deal with pulleys. They should be worn on the axle with the help of sleeves, and at its different ends. Naturally, both pulleys need to be balanced.
5. In order for the tape not to vibrate, it is necessary to apply a damper.
6. All movable parts should be connected to the motor.
7. You can also build a guide mechanism with which the processed material will be fed. For this, metal corners are used.
A homemade saw band saw should becarefully prepared for work. To do this, it should be tested and configured. The cutting tape must be strictly at right angles. Any slight bias can stop the operation of the machine and become life-threatening.
Note that the cutting tape must beas tight as possible. Use the driven pulley to adjust. With his help, you can properly adjust your machine. It should also be noted that the welding of band saws used in the manufacture (it’s quite simple to do it yourself) will provide good durability and stability of the machine.
Naturally, any technique needsperiodic repairs and inspections. For example, sharpening band saws with their own hands is quite simple. The main thing is to know its technology. For work the special machine is used. All work consists of several stages:
1. Initial sharpening (eliminates cracks that appear, restores the symmetry and profile of the teeth).
2. Cleaning cloth from sawdust and dust.
3. Wiring (to restore the rear and front corners).
4. Final sharpening. It eliminates all distortion and gives sharpness to the teeth.
If you do not have experience sharpening saws, then all actionsshould be done as carefully as possible. From this procedure depends on the quality of the device. If you are not confident in your abilities, then invite an experienced specialist.
First of all, to do some work for youneed complex equipment. For example, not every master can use a welding machine. Not everyone has a milling machine. Note that the entire structure must be sustainable. It should not forget about the mass of the material that will be processed.
Not everyone can figure out the drawing.Note that the disadvantage of such a device is quite wide cut. In general, if you want to build such a unit yourself, stock up with the necessary tools, material and patience.
Even after you can doThe presented construction should learn how to use it correctly. For example, try to follow all necessary safety rules. Note that in some cases the blade may burst, so if you are not sure of the strength of its mounting, then you are not too close to the machine.
Observe and such rules of operation of the device:
- The more the workpiece to be processed, the larger the teeth should be at the saw.
- It is better to use universal cutting tapes. In this case, you do not have to change the canvas every time you need to process any other material.
- Before making the device must bechoose the place where he will stand. This takes into account the size of the room, the presence of electrical wiring. Naturally, this place should be well ventilated.
- Before work, try to stretch the cutting tape as much as possible. Otherwise, the machine will not only not perform its functions, but also become hazardous to health.
- The unit should not work more than two hours in a row. After that, the tape is removed and left alone for at least a day.
- After long operation, the machine must be lubricated. Pick the right substance for your car.
- The correct tooth separation is obligatory.
That's all the features of manufacturing anduse band saw. Please note that this device requires appropriate care. If you see that it is not working properly, then it is better to postpone the start of its operation. Be attentive and careful.
