Cylindrical cutting head disc cutter with adjustable milling blade position

A cylindrical cutting head disc cutter with adjustable milling blade position comprises a cutter body, wherein a plurality of trench holes are formed in different places on the cutter body; cylindrical cutting heads are arranged in the trench holes; the upper ends of the cylindrical cutting heads adopt cutting edges, and the lower ends adopt wedge surfaces; the cylindrical cutting heads are fixed in the trench holes by set bolts through tightly supporting the parallel contact surfaces on one sides of the cylindrical cutting heads; the wedge surfaces are tightly matched with adjusting tips. Before adjusting the positions of the cutting edges, the set bolts are loosened, and then the positions of the tips are adjusted; if the positions of the cutting edges need to be moved towards the cutter body, the tips are screwed out by a certain space, and the cutting heads are slightly pressed towards the cutter body; if the positions of the cutting edges need to be moved away from the cutter body, the tips are screwed by a certain space, and the cutter body is ejected by a certain space; after finishing adjusting the positions of the cutting edges, the set bolts are tightly screwed to prevent the cutting heads from loosening during milling. The disc cutter has the characteristics of being long in service life, high in milling precision, good in chip removing property, and adjustable in the position of the milling blade.
