ABSTRACT:
A cutter head assembly for a wood planing machine includes a shaft, a plurality of cutter-mounting sleeve modules sleeved on the shaft, and a plurality of cutter modules respectively secured to the sleeve modules such that cutting edges of the cutter modules extend beyond outer wall surfaces of the sleeve modules. An angularly variable positioning mechanism includes an axially extending guiding member disposed on the mount segment, and a plurality of axially extending guided members disposed on inner wall surfaces of the sleeve modules to mate with the axially guiding member. By virtue of fitting engagement between the guiding member and a selected one of the guided member of each sleeve module that are sequentially sleeved onto the shaft, the cutting edges together define a cutting contour line that winds around the shaft.
