Description

Technical Field

[0001] The present invention relates to the technical field of guqin manufacturing, and in particular to a guqin surface manufacturing device and a manufacturing method thereof. Background Art

[0002] The guqin is a traditional Chinese musical instrument, about 120-130 cm long and made of high-quality wood. The body of the instrument is equipped with seven strings, note frets and pegs, and the vibration of the strings produces sound through the resonance cavity of the body. The frets on the surface of the instrument help adjust the pitch, while the tension of the strings is adjusted by the pegs. The playing techniques of the guqin, such as vibrato and glissando, create rich timbre. This instrument is not only used for music performance, but also carries a profound cultural connotation and is often combined with art forms such as ancient poetry and calligraphy.

[0003] In the prior art, since the bridge panel is wide at one end and narrow at the other end, it is necessary to cut both sides to form this shape during processing, and the upper and lower surfaces of the panel need to be flattened using a planer or a grinder before processing;

[0004] However, the existing processing method still has the following technical problems: the existing guqin surfaces are mostly made manually, and the processing methods vary depending on the makers. Especially when cutting and shaving boards, most craftsmen will adjust the cutting position and shaving thickness on both sides according to their experience.
