How to Use Bimetal Band Saw Blade 

Correct use of bi-metal band saw blades

     Bi-metal band saw blades are high quality tools. In order to ensure optimum performance and longevity, it is extremely important to choose the right saw blade, the correct running-in and the proper operating procedures.

1. The running-in of the saw blade:

  New saw blades must be worn in before they are officially used. A saw blade that is not worn or worn out has a service life of 1/3 or less of a worn-in saw blade. When the saw blade is run-in, only half of the normal feed pressure/rate and sawing speed can be used until the surface area of 300-1000 cm2 is sawn out. Then gradually enter the feed rate and saw

The speed is increased to normal. Sawdust sawing can see if the sawing pressure and conditions are correct.

2. Saw speed:

  The speed of the saw band is determined by the type of material, the width of the material, and the tensile force of the saw band. Harder materials must use a lower sawing speed; smaller widths must use a faster sawing speed.

3. Saw belt pressure and feed rate:

  The pressure and feed rate of the saw band are determined by the type of material and the width of the material. Harder materials and larger width materials require greater pressure and feed rates; softer materials and smaller widths require smaller pressures and feed rates.

4. Contour sawing:

Please cut the material according to your needs.

 Choose the most suitable type of saw blade; then select the width of the saw blade based on the minimum arc (radius) you need to saw the material. The smaller the curvature (radius), the narrower the width of the saw blade.

5. Saw blade tension:

   Before sawing with a new saw blade, the tension should be checked first. If necessary, tighten after a small amount of sawing. The pre-tensioning stress of the bi-metal band saw blade is 250-300 N/mm2.

6. Band saw guide:

The accuracy of the sawing depends on the setting of the band saw blade guide: the closer the device is to the material, the higher the sawing accuracy.

7. Cooling and lubrication:

Cooling and lubrication are indispensable during most metal sawing processes. For cast iron, brass, and some non-metallic materials. Such as plastics and graphite, etc., may or may not be lubricated during processing.
