The invention relates to a sleeved milling cutter for machining a cabinet door frame and a manufacturing method thereof. The sleeved milling cutter comprises a threaded shaft sleeve, a disc-shaped forming cutter, a disc-shaped rectangular cutter, a disc-shaped groove cutter, a profiling mold, a rolling bearing and a clamping nut. Each disc-shaped cutter is provided with a center hole, and each cutter center hole is matched with the threaded shaft sleeve. The rolling bearing is mounted on the upper sides of the disc-shaped cutters, and the profiling mold is arranged on the outer side of the rolling bearing. The disc-shaped forming cutter, the disc-shaped rectangular cutter, the disc-shaped groove cutter, the profiling mold and the rolling bearing are all fastened on the threaded shaft sleeve through the clamping nut. Four opened spanner positions are arranged on the outer circle of the clamping nut. Four evenly-divided scrap containing grooves are formed in a cutter body of each disc-shaped cutter. Carbide blades are tightly attached to welding cutter positions on the scrap containing grooves in a welding mode. By means of the sleeved milling cutter, the cabinet door frame can be machined at one time, the profiling mold and a cutter head are effectively combined into the sleeved milling cutter through the threaded shaft sleeve, the machining efficiency is high, each cutter can further be used independently, and cost is saved.
