With the rapid economic development, “precision shipbuilding” and “fast shipbuilding” have become the main trends in the development of the shipbuilding industry. Laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry.The sheet metal laser cutting machine has greatly promoted the upgrade of the precision shipbuilding industry.
The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. Laser technology has its uniqueness in shipbuilding, which is closely related to the processing and application characteristics of the ship itself and the characteristics of the laser manufacturing system.Steel is the most common industrial raw material, and there are many years of history and experience in cutting steel. Ships are life-carrying tools, and the requirements for manufacturing materials are very high. A small skew or a small problem in sheet cutting may cause disaster for the entire ship. Therefore, the metal cutting machine with no effect on the raw material during cutting, high precision and high safety factor will become the mainstream of the entire shipbuilding sheet metal manufacturing industry.
The shipbuilding industry is mainly based on steel plate raw materials. The use of metal laser cutter can replace some processing methods that require large-scale die punching, greatly shortening the production cycle and reducing processing costs. The use of laser cutting machine for blanking cancels the assembly margin, eliminates the phenomenon of on-site repair and cutting, reduces labor costs and sheet waste, and the frame assembly speed is significantly accelerated, and the assembly quality is significantly improved.The marine steel plate cut by laser has good slit quality, good verticality of the cut surface, and no slag. Moreover, the oxide layer is thin, the surface is smooth, no secondary processing is required, and it can be directly welded. And the thermal deformation is small, the curve cutting precision is high, and the high-strength ship board can be cut without obstacles. This provides a guarantee for the quality of raw materials in the shipbuilding industry, thereby reducing assembly workload, assembly cycle, material and labor costs.
Fiber laser technology is generally recognized as the main equipment for shipbuilding in the industry. No matter from the perspective of market competition or the direction of user application, the application of fiber laser cutting machine is becoming more and more common.Compared with the traditional production methods (flame cutting, plasma cutting), cnc metal laser cutter processing cost is low, the processing procedures are few, and the efficiency is high. The laser cutting machine has great advantages in dealing with the processing of medium and thick plates, and the speed is faster than traditional plasma cutting. As the power increases, the cutting speed of the sheet will continue to increase, and the ultimate cutting thickness of the sheet will also continue to increase.In addition to the advantages of cutting thicker and faster, with the increase of laser power, there are more processes for laser cutting. High-power high-speed bright surface cutting technology, that is, under the condition of sufficient power, use small nozzles, small air pressure, and high-power laser to cut carbon steel plates of different thicknesses at high speed to obtain smooth cutting sections and smaller processing tapers. The smooth cut surface facilitates subsequent processing by customers; at the same time, the taper can be basically controlled below 0.2mm on both sides, which can better meet customer requirements in certain high-precision processing industries.
Laser cutting is the development direction of modern metal processing technology and an indispensable processing equipment for the development of the shipbuilding industry.Senfeng laser cutting machineare also being researched and developed in the fields of high speed, high precision, large format, three-dimensional cutting and special material cutting, so as to continuously meet the growing market demand.
