۵- If you have not chosen the yield rate and linear speed of your band saw blade according to the size and material of the workpiece, you will definitely encounter vibration during cutting. To solve this problem, read the yield rate and cutting speed table.
۱- The main and most important cause of band saw blade teeth breaking is not choosing the correct tooth pitch according to the material and size of the work piece.To solve this problem, you can contact the technical experts of Tigh Saw.com. Or read the band saw blade tooth selection table.
۲- Band saw blade teeth are produced at different angles to carry chips and have better penetration. If the tooth angle you choose is not compatible with your work piece. Or the linear speed and yield rate are not set correctly. You will encounter a broken band saw blade tooth. To choose the right tooth angle, you can contact the technical experts of saw blade.com. Or read the article on the tooth angle of the band saw blade.
۳- Improper discharge of shavings from between the teeth is also one of the most important causes of band saw blade tooth breakage. To solve this issue, you must ensure the correct operation (rotation of the shaving brush during the movement of the saw blade and the integrity of the shaving brush wires).And if the chipping brush is defective, replace it.
۴- If the workpiece is not properly closed in the clamps of the machine. During cutting, it will move and cause an impact to the teeth of the band saw blade and break them. Therefore, before starting cutting, make sure that the work piece is accurately clamped in the clamps of the machine.
Rough cutting surface
Teeth slowing down
۱- The linear speed and the rate of error in arising. This problem is very impressive. And if the yield rate and linear speed are high. The teeth will slow down quickly. Our solution to solve this problem is to study the yield rate table and the cutting speed of the band saw blade.
۲- It is very important and necessary to use high-quality soapy liquid and observe the concentration of soapy liquid according to the cutting work piece.And if you don’t follow these tips, you will quickly face wear and tear of the teeth. To solve this problem, you can use cutting nano powders and read the table of soap water liquid concentration and linear speed of the band saw blade.
۳- If the tooth of the band saw blade is not selected correctly, it will cause a lot of pressure on the teeth of the band saw blade, this high pressure can quickly cause the teeth to slow down, to solve this problem, you can contact the technical experts of the saw blade dot com, get in touch or read the band saw blade tooth selection table.4- It is very important to coordinate the tooth angle of the band saw blade with the material and size of the work piece. If the angle of the tooth you choose is not in harmony with the material of your work piece, you will definitely encounter tooth wear. To learn about the tooth angles of the band saw blade, see the article Study the tooth angle of the band saw blade.
Note: If the yield rate and linear speed are correct. And the tooth angle is wrong. With wear and if the yield rate and linear speed are high. You will encounter broken band saw blade teeth.
Sliding of the band saw blade on the follies (blades of the band saw machine)
۱- The most important factor that causes the band saw blade to slip on the blades of the band saw machine. Corrosion and wear of the blades of the band saw machine. To solve this problem, be sure to replace or repair the blades of the band saw machine.2- Incorrect adjustment of band saw blade tension (low tension) is also one of the most important factors of band saw blade sliding on the machine’s foleys, as a result, always measure the tension of the band saw blade with the help of a tension meter. Set the device correctly.
Note: Normally, the tension of the band saw blade should be set between 180 and 220 bar.
۳- If the yield rate is too high. The pressure on the workpiece causes the band saw blade to get stuck in the groove. and sometimes turning foleys and sliding. The band saw blade will be on it. To solve this problem, read the yield rate and cutting speed table. And find the right yield rate for your crop.
Investigating the possible defects of band saw blade breakage
۱- Guides of the band saw machine (guide arms) if they do not work properly and are not completely aligned. They will cause the body of the band saw blade to break.To solve this issue, you must make sure that tungsten carbide, bearings and arms are healthy. And if the mentioned parts are defective. Replace or calibrate it.
۲- If the tension of the band saw blade is not adjusted correctly and the applied pressure is too much, you will definitely encounter the breakage of the band saw blade. To solve this problem, adjust the tension with the help of a tension meter. show
Note: Normally, the tension of the band saw blade should be set between 180 and 220 bar.
Investigation of possible cracking defects from the back of the band saw blade body
۱- If the bearings of the guide arms are broken or worn. They will increase the pressure on the back of the band saw blade and cause cracks. Therefore, if you encounter a crack on the back of the body of the band saw blade, be sure to check the bearings of the guide arms.And if you see any problems, replace them.
۲- Deterioration of the blades of the device and lack of balance of the blades are also one of the main causes of cracks on the back of the band saw blade, in case of cracks on the back of the band saw blade, make sure that the blades of the band saw are aligned and If you see any problem, fix it.
Investigating possible corrosion defects between band saw blade teeth
۱- Incorrect yield rate is one of the main causes of cracks inside the band saw blade, if the yield rate is high due to the increase in the volume of the shavings, it will increase the pressure on the teeth of the band saw blade and create cracks between the teeth of the band saw blade. To solve this problem, you can read the yield rate and cutting speed table.
۲- If the tooth pitch is not selected according to the size of the work piece.Filing will be difficult and will cause pressure on the teeth. To solve this problem, you can read the band saw blade tooth selection table or contact the technical experts of saw blade.com.
۳- If the tension of the band saw blade is not adjusted properly and the tension of the band saw blade is low, when the band saw blade hits the workpiece, due to the lack of proper guidance of the band saw blade, you will definitely encounter cracking between the teeth of the band saw blade, for To solve this problem, be sure to use a band saw blade tension meter and set the tension of the band saw blade correctly.
Note: Normally, the tension of the band saw blade should be set between 180 and 220 bar.4- If the discharge of the shavings from between the teeth is not done properly, it will cause the accumulation of shavings between the teeth of the band saw blade and increase the pressure on the teeth and cause cracking between the teeth of the band saw blade. To solve this problem, it is necessary to and ensure the correct operation of the shaving brush, and if it is defective and does not rotate correctly, replace or repair it.
