    Rough Surface

    Rough Surface

    The stem’s cutting surface is in general rougher during the use of a gang saw, than a circular saw. Under certain circumstances, cutting with the gang saw can lead to a rougher surface of the stem, which might be too rough to ensure economic further processing.

    Possible causes:

    The gang saw is set unevenly
    • Dismantlement and repair (re-set of teeth)
    The gang saw has an irregular side-clearance of stellite teeth
    • Dismantlement and repair (re-sharpening a/o new stellite tips)
    The gang saw is dull
    • Re-sharpening of the gang saw
    Wood is too wet or too dry and tends to a rougher surface
    • Sawmill needs to check and adjust the preparation of the wood
