Description

Technical Field

[0002] As a means of transportation for water transportation, ships have gradually increased in tonnage as the demand for carrying capacity has gradually increased. With the development of science and technology, most ships have been transformed into steel structures to carry more cargo. During the production and construction of ship steel structure projects, cutting devices are usually required to perform turning, milling, drilling, planing and other processing procedures on the steel structures.
