Gang saw blades get hot

The wood’s cutting surface can display burn marks, is getting rough and the gang saw blades are getting unusually/particularly hot (show blue stains).

Possible causes:

Tension of the gang saw is too soft, which means the gang saw’s tension is too high and therefore cannot be tensioned correctly in the frame.

• Dismantlement and repair (tensioning)

Missing tension in the gang  mill frame (mill saw is too low on tension)

•  Use of tension measuring device to measure the clamping of the gang saw blade in the frame – if necessary, re-adjustment

Projection of the saw is not correct

• Adjustment of the projection by a mechanic a/o inspection of the positioning of the holes in the gang saw blade

Tooth tips are dull

• Re-sharpen mill saw

Wrong shape of tooth; wrong angle; wrong height of tooth

• Inspection and adjustment of tooth geometry in consideration of the type of wood, cutting height, feed speed etc.

Set-up is out of the plumb

•  Inspection and re-adjustment
  

Gang saw is not angular in set-up

• Re-adjust mill saws in the frame with the aid of a ruler or angle/elbow
