How to run in the saw blade on the band saw?

The saw blade of a new band saw needs to be run-in before it is officially used in order to make good use of the saw blade. If the saw blade is used without running-in, the specific service life will be greatly reduced. The service life of non-running or running-in saw blades is less than that of running-in saw blades 1/3 or less. When the saw blade on the band saw is running in, only half of the normal feed pressure/speed and sawing speed can be used until the surface area of 300- 1000 cm2 is sawed on the band saw. Then gradually increase the feed speed and sawing speed of the band saw to normal values.

First, whether the sawing pressure and conditions are correct can be seen from the sawdust sawed by the band saw:

1, very fine or powdery sawdust, indicating that the feed speed should be increased or the sawing speed should be reduced.

2. Coarse, heavy or blue sawdust indicates that the saw blade is overloaded, so the feed speed should be reduced or the saw belt speed should be increased. Loose coiled sawdust indicates an ideal sawing state.

Second, sawing speed: the sawing speed is determined by the type of material, the width of the material and the tension of the sawing belt;

1, harder materials must use lower sawing speed.

2, smaller width must use faster sawing speed.

Third, the saw belt pressure and feed speed: the saw belt pressure and feed speed are determined by the type and width of the material.

1, harder materials and wider materials need to use greater pressure and feed speed.

2. Softer materials and smaller widths require less pressure and feeding speed.

4. Profile sawing: Please select the most suitable saw blade type according to the sawing material you need; Then choose the width of the saw blade according to the minimum radian (radius) of the sawing material you need. The smaller the radian (radius), the narrower the width of the saw blade.

Verb (abbreviation of verb) tension of saw blade: Before sawing with a new saw blade, check its tension. If necessary, tighten it after a small amount of sawing.

6. Band saw guide: the sawing accuracy depends on the setting of band saw guide: the closer the equipment is to the material, the higher the sawing accuracy.

7. Cooling and lubrication: In most metal sawing processes, cooling and lubrication are essential. For cast iron, brass and some nonmetallic materials, such as plastics and graphite, lubrication may or may not be needed during machining.

The running-in of saw blade is also a technology, and our explanation above is only written, and employees without much experience know little about it. Practice more with experienced masters, accumulate experience and operate more slowly, and you will feel that it is most appropriate to know how to adjust the saw blade.
