Adjustment of leveling Components
1. The components are equipped with two adjusting systems in which one is the axial
cutter and the other is a vertical detector. The axial adjustment may move the cutter
by adjusting two knobs: C and D (Fig.15). This adjustment is frequent and needs to
be made while the cutter is operating.
2. There is a direction board at the back of the machine as shown in Fig.16 (”+”)
forward and (“-”) backward. The vertical adjustment in radial direction may be made
by adjusting bolts F and G (in Fig.14) to change the clearance of detector E to be
accommodate the changes in the cutter diameter. This adjustment should be made
while changing the cutter (when the cutter becomes blunt).
Note: bolts F and G need to be adjusted to the same number of turns so that the
detector and the worktable are parallel. The maximum width of the edge banding
beyond both sides of the work piece is 2mm each side (as shown in Fig. 17).
