LASER CUTTING MATERIALS
The variety of metal materials used for laser cutting covers a wide range of metals and their alloys from lightweight to high strength. Here are some common metal materials that can be effectively processed by laser cutting machines:
Aluminum alloy, with low density, good conductivity and corrosion resistance, is widely used in aerospace, construction, transportation and other fields. Aluminum 6061, 6061-T6 Aluminum 2024 Aluminum 5052 Aluminum 5083 Aluminum 6063 Aluminum 6082 Aluminum 7075, 7075-T6 Aluminum ADC12 (A380)
Widely used in the manufacturing of mechanical parts. Carbon steel has good mechanical properties and its hardness and toughness can be changed through heat treatment. Steel 1018, 1020, 1025, 1045, 1215, 4130, 4140, 4340, 5140, A36 Die steel Alloy steel Chisel tool steel Spring steel High speed steel Cold rolled steel Bearing steel
High strength, low density, good corrosion resistance, used in aero-engines, medical devices and other high-performance areas Magnesium Alloy AZ31B Magnesium Alloy AZ91D
It is a commonly used thermoplastic with good mechanical properties and impact strength, easy to process, and widely used in prototyping and industrial parts.
Nylon is widely used in engineering parts because of its excellent mechanical properties, abrasion resistance and chemical resistance, but its moisture absorption needs attention.
PC has high toughness, good mechanical processing performance, and excellent impact strength, making it suitable for applications that require high strength and transparency.
POM has very high mechanical strength and hardness, good abrasion resistance, and is one of the engineering thermoplastics with the highest machinability among plastics.
PTFE has a very low coefficient of friction and excellent chemical resistance, making it suitable for applications requiring lubricity or corrosion resistance.
TYPES OF SURFACE TREATMENT PROCESSES
There are a wide variety of surface treatment processes designed to enhance the performance of a part, such as increasing corrosion resistance, wear resistance, aesthetics, or other specific features.
Electroplating
Using the principle of electrolysis to deposit a layer of metal plating on a metal surface, such as zinc, copper, nickel, chromium, etc., to enhance corrosion resistance, wear resistance or decorative properties.
Anodic Oxidation
Especially for aluminium and aluminium alloys, it generates a dense film of aluminium oxide by electrochemical reaction, which improves corrosion and abrasion resistance, and can also be coloured.
Wire drawing
By forming a regular fine line texture on the surface of the metal, thus giving the product a unique texture and visual effect.
Sandblasting
The use of a high-pressure jet of abrasive material (e.g. grit) to remove surface impurities and provide a uniform roughness that facilitates the adhesion of subsequent coatings.
DLC Coating
An amorphous thin film of carbon, similar in structure and properties to natural diamond, but without the crystal structure, DLC coatings are widely used in industry due to their excellent properties.
Marking
Although not a surface coating treatment, laser marking can leave a permanent mark on a metal surface for identification, tracking or decorative purposes.
TOLERANCE OF SHEET METAL LASER CUTTING
The tolerance of sheet metal laser cutting refers to the allowable deviation between the actual size and the theoretical size during the cutting process. The size of the tolerance depends on multiple factors, including material type, thickness, accuracy of the laser cutting equipment, operator skills, selection of auxiliary gas, cutting speed, and whether a closed-loop control system is used.
Maximum Part Size
1200 x 800 x 500mm
Minimum Part Size
5 x 5 x 5 mm
Dimensional tolerance
±0.1mm
Cutting width tolerance
± 0.05mm to ± 0.1mm
Verticality tolerance
Metal: 0.8 mm; Plastic: 1.5 mm. The thicker the wall thickness, the better the structural integrity.
Position tolerance
± 0.1mm
WORKING PRINCIPLE, ADVANTAGES AND APPLICATIONS
1. What is laser cutting?
1. Metal laser cutting is a modern material processing technology that utilizes a high energy density laser beam to cut metal materials. This technique is based on the highly directional and high energy density properties of the laser, which are able to generate enough heat on the metal surface to cause rapid melting and vaporization of the material, resulting in a cut.
2. Advantage:
Metal laser cutting is widely used in various fields, such as automotive, aviation, shipbuilding, machinery manufacturing, electronics, construction, and art manufacturing. With the advancement of laser technology, the scope and efficiency of metal laser cutting are constantly expanding and improving. The advantages of metal laser cutting include:
A、High precision
Capable of achieving very precise cutting, with narrow slit width and accurate position.
B、High efficiency
Fast cutting speed, suitable for large-scale production.
C、Flexibility
Able to cut complex shapes and curves without being limited by cutting modes.
D、Low maintenance cost
Non contact cutting reduces tool wear and replacement frequency.

A 1、Metal - The main purpose of laser cutting is to accurately cut various metals in various industries. The metals that can be cut include aluminum, brass, copper, gold, nickel, silver, steel, titanium, tungsten, etc. 2、Ceramics - Fiber laser is also suitable for cutting various ceramics. 3、Glass - can cut various types of glass into the precise size required. 4、Plastics and polymers 5、Wood (although precautions should be taken to prevent burnt spots/burns)
A The working principle of laser cutting is to pass a high-power, highly focused laser beam through the material, resulting in a clean and smooth surface for cutting. The beam can be pulsed or continuous wave.In some ways, the cutting process is similar to drilling and carving. Drilling is the process of creating a "through hole" or indentation in a material. These indentations are like carvings and are also considered as "cuts" in the material
