Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the quality of the workpiece.The modern laser has become the “sword” of people's fantasy pursuit of “cutting iron like mud”.Laser cutting is an indispensable equipment in sheet metal processing, and is the most representative procedure in sheet metal processing industry.Dongji sheet metal is a large laser cutting processing plant from Jiangmen area, with 3 large-power laser cutting machines in Jiangmen, specializing in laser cutting sheet metal processing.
Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the quality of the workpiece.Laser cutting is realized by using the high power density energy generated by laser focusing.And controlled by computer, through the pulse laser discharge, thus the output controlled repeated high frequency pulse laser, the formation of a certain frequency, pulse width of the beam, the pulse laser beam through the light path transmission and reflection and through the focusing lens group focused on the machining surface, forming a subtle, high energy density, intensity, focal spot near to processing surface, with instantaneous high temperature melting or gasification materials processed.The modern laser has become the “sword” of people's fantasy pursuit of “cutting iron like mud”.Laser cutting is an indispensable equipment in sheet metal processing, and is the most representative procedure in sheet metal processing industry.Dongji sheet metal is a large laser cutting processing plant from Jiangmen area, with 3 large-power laser cutting machines in Jiangmen, specializing in laser cutting sheet metal processing.
Each high energy laser pulse sputtered a small hole on the surface of the object in an instant. Under the control of the computer, the laser machining head and the processed material hit points in continuous relative motion according to the pre-drawn figure, so that the object can be processed into the desired shape.When cutting externally, a stream of gas coaxial with the beam is ejected from the cutting head and the melted or vaporized material is blown out from the bottom of the cut （note: if there is a thermal effect between the gas blown out and the material to be cut, the reaction will provide additional energy for cutting;The airflow also has the function of cooling the cut surface, reducing the heat affected area and keeping the focusing mirror free from contamination.Compared with the traditional plate processing method, laser cutting has the advantages of high cutting quality （narrow incision width, small heat affected area, smooth incision）， high cutting speed, high flexibility （can cut any shape at will）， wide material adaptability and so on.

Numerical control bending processing advantages
CNC bending is formed by laser or CNC punching and other processed sheet materials through pressure and mold.The size and accuracy of bending are closely related to the type of material, thickness, coefficient, resilience and the use of the die.Our sheet metal factory undertake external processing, external CNC bending processing, Jiangmen large sheet metal factory, Jiangmen Sheet metal factory, Jiangmen sheet metal processing including CNC bending processing, CNC bending machine imported from Japan, and laser cutting machine, CNC punching machine, laser cutting processing.
Numerical control bending is different from ordinary bending
CNC bending machine and ordinary bending machine are made of stainless steel, ordinary steel plate and other plates.The difference is whether there is computer control and automatic feedback.The different results are: machining speed, machining precision and machining efficiency.
Numerical control bending principle
Plate bending is the process of changing the Angle of a plate or sheet.If bend the plate into V shape, U shape, etc.Generally speaking, sheet metal bending has two methods: one is mold bending, used for complex structure, small volume, large amount of processing of sheet metal structure;The other is bending with a bending machine, used for processing large or small size of the structure of the sheet metal structure.These two bending methods have their own principles, characteristics and applicability.

Welding is a machining or sculptural process in which materials（usually metal or thermoplastic）are joined together, as opposed to low-temperature metal joining techniques such as brazing and welding, which do not melt base metals.In addition to melting base metals, filler materials are usually added to the joints to form a weld pool（pool），which cools the pool to form a joint based on a welded structure （butt joint, full depth, rounded corners, etc.）that is stronger than the base metal (base metal).Pressure can also be used in conjunction with heat or alone to produce a weld.
