Wood-Mizer sawmill adjustment

We’d like to bring to your attention some of the elements of sawmill adjustment, which influence both blade life and a cut quality.

Step 1. Blade Pulley Alignment
It is possible to adjust the Blade Pulleys on all Wood-Mizer sawmills. The blade pulleys should be completely parallel to each other and in the same plane.

You can check if the blade pulleys are correctly aligned by installing and tensioning a blade.Rotate the blade in one direction and then measure the distance from the bottom of the gullet to the front of the blade pulley at the top, bottom and side on both pulleys. Then rotate the blade in the other direction and check the same measurements.

If the pulleys are correctly aligned, the distance between the bottom of the gullet and the edge of the pulley wheel should be between 3 & 4 mm for both pulleys at all points and in both rotation directions. If this is not the case, the pulley wheels are not correctly aligned.

Step 2. Blade guide adjustment
This adjustment is very important. The downward deflection of the roller on the blade depends on the roller type. This should be 3-4 mm for block/roller guides and 6 mm for rollers without blocks.

Rollers must be adjusted in both planes according to the manual for the sawmill series. The tolerance is below 1 mm.

All the adjustments noted above influence blade life and cut quality. If the blade pulley wheels and the rollers are not correctly aligned the blade will be constantly working under stress and this will result in poor cutting and short blade life.

Please refer to the manual for your sawmill to find the correct settings for your mill.
