Curtain Wall Processing Industry Introduction

The curtain wall processing industry is an important sector within the construction industry, primarily engaged in the processing, manufacturing, and installation of architectural curtain wall products. A curtain wall refers to the non-load-bearing part of a building’s exterior wall, typically composed of materials such as aluminum alloy, glass, stone, and metal panels, used for decoration and thermal insulation. The curtain wall processing industry involves the processing and manufacturing of various curtain wall materials, including cutting, punching, and welding of aluminum alloy profiles, cutting and processing of glass, cutting and shaping of stone, and other related activities. In the case of processing metal curtain walls, the industry requires expertise in various processing techniques such as CNC machining, bending, cutting, punching, and spraying, to ensure the precision and quality of curtain wall products.

Difficulties of the Traditional CNC Router 

For aluminum alloy metal curtain wall processing, most customers use the traditional CNC engraving machine to produce and process, for the aluminum plate below 3mm, generally choose F4 cutting tool, which is easy to produce three problems.

1.When the cutting head of the CNC engraving machine processes aluminum, it will directly contact the metal material, and the cutting tool will produce loss, which will produce a consumable cost for the customer.

2.In the process of cutting, the tool of F4 will cut the material next to it, resulting in material loss.

3.Because the cutting tool of the engraving machine can only round the corners, when the metal curtain wall has the hollowing demand of the square shape, it can not be cut at a right Angle, which limits the finished effect of the curtain wall.

Solution Plan for the Curtain Wall Processing Industry

As for the curtain wall industry, we suggest the customer to choose the fiber laser cutter.

Laser cutting machine produces a laser beam with high energy density through the laser beam, the laser beam is focused on the surface of the workpiece, the high energy density of the laser beam makes the material locally heated, melted or vaporized, so as to achieve cutting, engraving or drilling and other processing purposes.

According to the working principle of the laser cutting machine, we can understand that the laser equipment can effectively solve the three processing problems of customers.

1. The beam of the laser cutting machine does not directly contact the metal material, there will be no problem of tool loss, effectively reducing the cost of use;

2. The laser cutting beam is more concentrated after focusing, the slit is smaller, and the material loss and waste are less;

3. When cutting sharp corners, it can effectively process according to cutting graphics to maximize the expected cutting effect.

Suggested Model of Fiber Laser Cutting Machine

1.Because aluminum has a certain reflectivity, the equipment surrounding the structure can effectively prevent the damage caused by light reflection to workers and improve safety;

2. The exchange table can realize the feeding of the plate at the same time of cutting, improving the processing efficiency;

3. The effective processing stroke of the table is 6000*2500mm, which can load different specifications of metal sheets for processing, and has a wide range of application.

● Plate condition: plate model, plate rust degree, plate flatness;

● Cutting head status: collimation/focus ratio, whether the lens is contaminated, cutting head verticality, cutting head stability;

● Machine tool conditions: machine tool acceleration, operating stability, load-bearing performance, long-term use deformation, etc.;

● Cutting system: system response speed, system functionality, system stability;

Cutting Type and Laser Power Trend Table
Material	Auxiliary gas	Laser power
Carbon steel bright cutting	O2	1. The higher the power, the thicker the bright surface cutting thickness; 2. The thickness of the plate is certain, and there is a power range for bright surface cutting. If it is too small, bright surface cutting cannot be achieved, and if the power is too large, the cutting quality and efficiency will not be improved; 3. The higher the power, the faster the perforation speed of thick plates, and the phenomenon of blast holes will be reduced;
Carbon steel frosted cutting	O2	1. The thickness of the plate is certain. There is a power range for frosted surface cutting. If it is too small, cutting cannot be achieved. If the power is too large, the entire cutting surface will melt. If the cutting seam is too large, good cutting quality will not be obtained; 2. The higher the power, the faster the perforation speed of thick plates, and the phenomenon of blast holes will be reduced;
Stainless steel/aluminum alloy/copper alloy, etc.	N2/Air	1. As the laser power increases, the cutting efficiency of each plate thickness shows an upward trend; 2. As the laser power increases, the cutting thickness increases, and the slag hanging phenomenon is reduced or eliminated; 3. The higher the power, the faster the perforation speed of thick plates, and the phenomenon of blast holes will be reduced;

Nozzle status

The center of the nozzle is not coaxial with the center of the laser, the nozzle is deformed, or there are melt stains on the nozzle.

When the cutting gas is blown out, the gas output will be uneven, making it easier for the cutting section to have melt stains on one side but not on the other side. Thick plates will have a serious impact, sometimes making it impossible to cut;

When cutting workpieces with sharp corners or small angles, local over-melting is likely to occur;

When perforating before cutting, the perforation is unstable, the penetration conditions are difficult to grasp, and the time is difficult to control;

Cutting Parameter Guidance List

Basics of Cutting Technology

Gas pressure

When laser cutting, different cutting gases and pressures are selected according to the different materials of the cutting plate. The main functions of the cutting gas are: combustion support and heat dissipation, blowing off slag, preventing slag splash from rebounding into the nozzle, damaging the protective lens or Focusing lenses, etc.

Function of gas	Specific impact
For cutting	1. When the air pressure is insufficient, the plate cannot be cut through, the slag is pushed upward, or the cutting speed is low; 2. The air pressure is too high, causing the cutting surface to partially melt, the cutting slit to be too wide, and the cross section to be rough;
For piercing	1. When the air pressure is too low, it is difficult for the laser to penetrate the cutting plate, and the drilling time is long and the efficiency is low; 2. If the air pressure is too large and the hole diameter is too large, the plate will heat up, easily causing blast holes and unstable perforation;

1)Cutting gas purity requirements:

2) Cutting gas consumption

The variables related to cutting gas consumption include the following:

● Nozzle diameter

● Cutting air pressure

● Laser cutting time length

Estimation of cutting gas consumption: The consumption during standard pressure cutting and high-pressure cutting is listed below, so that the required cutting gas can be roughly estimated.

Reduce gas consumption. The data accumulation of machine tools can be used to make different estimates for the determined material variety and material thickness.

Standard pressure cutting: Standard pressure cutting is cutting where the pressure at the nozzle outlet is less than 6 bar. Oxygen or nitrogen is required as cutting gas.

For standard pressure cutting with O2, the flow pressure available at the machine connection is at least 8 bar (at gas consumption of 10 Nm3/h, nozzle outlet

Ø1.7mm, and the cutting air pressure is 6 bar).

High-pressure cutting: High-pressure cutting refers to cutting where the pressure at the nozzle is greater than 6 bar. Generally speaking, nitrogen is used as cutting gas. In rare cases, nitrogen is used as cutting gas.

Oxygen is also used in this case. High-pressure cutting is offered as an option for machining stainless steel and aluminum alloy profiles.

3) Input pipeline for cutting gas supply

Cutting gas connection location

● The input pipeline of cutting gas is laid from the user's side to the connection point of the machine tool inlet.

● The air supply pipe must be installed to the connection position indicated in the installation drawing.

● The connecting pipe arrangement must be at least 150 mm above the ground. The pipe before the connection point must have at least 1 m of free running section to

This allows the pipe to be bent downward when replacing the filter.

● The installation of the entire gas transmission system, from gas storage bottles or centralized gas tanks to machine tools, is all accomplished through pipelines.

● The carburetor must be designed to accommodate the maximum consumption of all connected machine tools. For this purpose, the pipeline from the carburetor to the machine tool must be

Keep the lay as short as possible.

● When designing and installing an external gas transmission system, pay attention to the input pipeline at the machine tool connection location and the connection location itself to avoid freezing.

● A stop cock must be installed in each inlet line to an individual machine tool. so that the input pipeline can stop the input, for example, in

During service, the injection valve at the connection point of the machine tool can be vented
