The invention relates to an automatic
metal milling device, which relates to the related technical field of milling, and comprises a
machine tool, a rotating piece, a connector, an annular baffle, a shell, an
air pump, an electric driving sliding block, an embedded sleeve, a milling head
assembly, a switching mechanism, a detection cleaning mechanism and a prompting mechanism, the problems that in the prior art, a semicircular cover combination structure is mainly adopted for preventing waste scraps from splashing, cleaning is not taken into consideration, non-
scrap-iron materials cannot be effectively treated through a magnetic adsorption mode, the
machining environment is affected, and the follow-up
machining precision is reduced or the cutter is broken due to deformation and bending generated by abrasion and the like in the using process of the cutter can be solved. However, the technology lacks the function of automatically detecting the abrasion, deformation and other states of the cutter, and the switching between the traditional milling heads mainly depends on manual operation or a simple mechanical structure, so that the consumed time is long, the precision is limited, and the automatic
machining efficiency is influenced.
