Chavez imported EDGE Ruijie saw blade from the United States. Based on the real use of the partners, we have summarized some factors that affect the life of the saw blade, which can be used for your reference. Correctly treating each influencing factor can effectively extend the life of the bi-metal band saw blade and obtain the sawing efficiency of the band saw blade, which saves you cost.
1. Feed rate. The feed rate is too low and it is easy to wipe the teeth. Too high will cause the sawtooth to fatigue in advance, the tip of the tooth will wear too fast, and it will easily break the tooth.
2. Saw belt tension. The standard value is 11kg~14kg. Below 11kg: poor weld seam, curved sawing, and strip fatigue. More than 14kg: The potential band saw blade is easy to break, and the machine is prone to fatigue.
3. Band saw speed. The correct band saw blade speed can increase the life of the band saw blade! For harder materials, the speed of the band saw blade is usually reduced. For softer materials, the speed of the band saw blade is also increased.
4. Run-in procedure. The new band saw blade has not been tried yet, the serrations are extremely sharp and have a certain number of burrs. Through the process of "fine grinding" the saw teeth, it is necessary to extend the use time of the saw blade. In general, the speed of the band saw blade is reduced to half the normal speed.
5. Number of teeth selection. Different tooth types are available for different materials. Choosing the right number of teeth can increase the life of the band saw blade. 6. The quality and type of band saw blade. The hardness and impact resistance of different brands will be different. Chavez saw blade imported from the United States, quality assurance.
7. Machine model. Select the appropriate size of the blade according to the machine model. If you choose a high-quality sawing machine, you must choose a better quality saw blade.
8. Wheels. Correct adjustment of the wheel will have an unexpected effect. The items that should be checked are: Correct correction, bearing status.
9. Machine status. The degree of oldness of the machine and whether the machine is properly maintained will affect the sawing of the band saw blade.
10. Material mechanical saw cutting performance. The steel properties of the bi-metal band saw blade steel affect the life of the tool, and the material is the same, but reflects the cutting performance of the mechanical saw.
11. Guide arm. The guide arm is as close as possible to the workpiece so that the straight line of the saw can extend the life of the saw band. If the guide arm is opened more, it is more likely to encounter the problem that the band saw blade is bent.
12. Coolant. The coolant acts to lubricate, cool, and clean the iron filings. Fine iron filings can generate heat due to friction and shorten the life of the saw blade. The color of the iron scraps of the normal band saw blade should be bright, and the iron scraps with heavy load on the band saw blade are thick, blue, gray or black.
13. Orientation. The guide wheels of the bi-metal band saw blade should support and straighten the steel strip. When the adjustment is normal, the bi-metal band saw blade reduces the sawing track curvature and reduces the swing of the saw band to reduce the impact.
14. Material hardness. The hardness of the material directly affects the service life of the bi-metal band saw blade.
15. Material shape. A small size solid body can cause a large impact on the saw blade, and the impact may shorten the life of the band saw blade.
16. The number of saws. If the sawing time is too long, it will affect the life of the saw blade.
17. Temperature. Room temperature also affects the viscosity and performance of hydraulic oil, feed, etc.
