Blade maintenance

One hundred years of experience in manufacturing band saw blades and a competent group of employees enable the company Alber to quickly and unbureaucratically pass on knowledge about band saw blades and the associated machines to our customers.

Unsatisfactory cutting results are often caused by the band saw (machine) and not necessarily by the band saw blade. We look forward to advising you in that respect. Use the opportunity and get in touch with our contacts in your region.

We also offer you a small workshop for employees from the sharpening room in our company.

Tips for blade maintenance

1. Correct blade thickness
The blade thickness for the wood band saws running at high speed may not exceed one thousandth of the roller diameter. For example, a blade thickness of 0.7 mm for a roller diameter of 700 mm. Slightly thicker blades may only be used for smaller machines which typically run at lower speed.

2. Correct adjustment
Adjust the saw blade in such a manner that it runs in the centre of the upper lining under all circumstances. The teeth may not protrude from the rim under any circumstances, otherwise the saw blade will be warped and crack.

3. Adjustment of the rear roller
While the machine idles, the distance between the rear of the saw blade and the rear roller of the saw blade should amount to 1-1.5 mm. The rear of the blade may only touch the rear roller while sawing, otherwise the rear of the blade and the rear roller will become too hot, resulting in tensions and cracks.

4. Releasing the tension of the saw blade
If the machine is not being used for a longer period of time, the tension of the saw blade should be released. On the one hand, this prevents the occurrence of a one-sided deformation of the wheel linings; on the other hand, this ensures that the blade will expand while sawing or at high room temperature and shrink when cooling down. If the blade was tightly stretched when sawing, it will be overstretched when cooling and consequently crack quicker.

5. Resharpening in due time
This is particularly important for the extension of the service life of the saw blade. Dull blades warp and heat up, quickly resulting in tensions and cracks.
