Description

technical field [0001] The invention relates to the technical field of letterbox processing, in particular to a novel letterbox device. Background technique [0002] During the processing of letterboxes, the outer surface is prone to unevenness. Generally, grinding is required. The surface quality after grinding by the traditional grinding method is poor, the grinding speed is slow and the efficiency is low, and the grinding debris is flying during the grinding process. Damage to the health of the operator, and the smoothing operation steps are cumbersome, so there is an urgent need to develop a letterbox smoothing processing device with good smoothing effect, time-saving and labor-saving, and high work efficiency. Contents of the invention [0003] The object of the present invention is to provide a method for overcoming the above-mentioned defects in the prior art. [0004] A new type of letterbox device according to the present invention comprises a main base body, a f...
