Function and requirement of pre-trimming cutter
The pre-trimming cutter 3 and plane cutter 2 installed onto the bottom spindle. See (Figure
13), the pre-trimming cutter 3 mills a right angle at the right bottom corner of timber. When the
profile of this right angle touches the inner surface of guiding board 4, the timber would be
guided by guiding board 4 and no longer guided by feeding fence 1. Then this right angle will
be milled by right vertical milling cutter 5. Generally mill about 0.5mm which is set already
before leaving the factory. Due to the pre-trimming cutter 3 and bottom spindle are radial
adjusted together, the diameter of these two must be set right with one another. The OD of
pre-trimming cutter 3 needs to be bigger than the diameter of plane cutter 2 about 20mm.
