During the process of flaking wood chips arise, which are liable to certain quality criteria. The regular examination of the wood chips quality is routine work in a sawmill. Due to the addition of supporting sieves/filter machine operators are able t...

The customer criticises an unsteady course of the saw blade. This error is noticeable visually and acoustically in different degrees of expression. The rate of rotation on the wave needs to be measured with a gauge and compared with the specification...

An incorrect feed of round wood to the saw blade can lead to lateral pressure onto the saw blade, which causes tooth damage due to deflection of the blade. (In extreme cases the tooth can cut into the enclosure of the saw.) The correct feed of the wo...

Foreign bodies (impurities) in round wood can cause damage to the carbide tooth during cross cutting. This damage can be fixed at TKM Spring-Tooth-Saw by individual tooth changes in the built-in state. A cut-off saw with set teeth needs to be dismant...
