When manufacturing machines knives, various tolerances need to be considered, e.g. the so-called lateral runout. This tolerance indicates the lateral movement of a rotating circular knife.
Manufacturers of Log Saw machines tolerate a maximum lateral runout of 0.2 mm for the log saw blade with a diameter of 610 mm.
This means that the blade moves at the outer diameter during a full revolution max. 0.2 mm from the right to the left side.
The IKS Klingelnberg Group manufactures log saw blades with a diameter of 610 mm with a max. lateral runout of 0.15 mm, 25 % less than the required tolerance of the OEM. Log Saw blades with bigger diameters (up to 1,200 mm) are also manufactured below the OEM tolerance.
The lateral runout and other tolerances are checked on the sharpening machine and if a blade is measured within all required tolerances a laser device engraves them on the blade. Blades which exceed one of the tolerances are rejected and need to be reworked.
