Laser cutting

Laser cutting

Laser cutting is a highly precise and efficient manufacturing process that uses a laser beam to cut through various materials. The laser beam is focused on the material to be cut, and the intense heat of the beam melts, vaporizes, or burns away the material along the cut line. The laser beam can be controlled by computer-aided design (CAD) software to create intricate and precise cuts that are difficult or impossible to achieve with traditional cutting methods.

Laser-cutting technology has revolutionized the manufacturing industry, allowing for faster and more accurate production of parts and components for a variety of industries, including automotive, aerospace, medical, and electronics. Laser cutting machines are capable of cutting a wide range of materials, including metals, plastics, wood, leather, and fabrics, with high precision and repeatability.

The laser cutting process offers many benefits over traditional cutting methods, including faster production times, greater precision, and reduced waste. Additionally, laser cutting machines can be programmed to cut complex shapes and patterns, making it an ideal technology for prototyping and small-batch production runs. Whether you’re a hobbyist, a small business owner, or a large-scale manufacturer, laser cutting offers an efficient and cost-effective way to produce high-quality parts and components.

Laser vapor cutting

Laser vapor cutting

Using a high energy density laser beam to heat the material, the heated material rapidly reaches its boiling point and the material vaporizes, forming vapors. These vapors are ejected at a high rate and form a cut in the material. A high power and power density are required for laser vapor cutting. Laser vapor cutting is mostly used for cutting very thin metallic materials and non-metallic materials (such as paper, cloth, wood, plastic and rubber)

Laser fusion cutting

Laser fusion cutting

In laser fusion cutting, the metal material is melted by laser heating, and then non-oxidizing gases (Ar, He, N, etc.) are sprayed through a nozzle coaxial to the beam, relying on the strong pressure of the gases to expel the liquid metal and form the kerf. The energy required is only 1/10 of vapor cutting. Laser melting cutting is mainly used for cutting some materials that are not easy to oxidize or reactive metals, such as stainless steel, titanium, aluminum and its alloys, etc.

Laser oxygen cutting

Laser oxygen cutting

Laser oxygen cutting uses a laser as a preheating heat source and oxygen as the cutting gas. Oxygen reacts with the cutting metal, releasing a large amount of oxidation heat. The laser oxygen cutting energy is half of molten cutting, while the cutting speed is much higher than laser vapor and molten cutting. Laser oxygen cutting is mainly used for carbon steel, titanium steel and heat-treated steel and other metal materials that are susceptible to oxidation.

Laser cutting advantage

Laser cutting is with fast cutting speed, high precision, and high-quality cutting edge. When used in industry, the cutting is repeatable, flexible, and easy to cut at a complex design. Easy to handle, Just send us your design, and we can provide competitive prices, fast delivery and high-quality one-stop service.

Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can obtain better-cutting quality.

  1.  Laser cutting kerf is thin and narrow, the two sides of the cut are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm.
  2. The cut surface is smooth and beautiful, and the surface roughness is only a few tens of microns, even laser cutting can be used as the last process without mechanical processing, and the parts can be used directly.
  3. After processing the laser cutting, the width of the heat-affected zone is very small, the properties of the material near the cut are almost unaffected, the deformation of the parts is small, the cutting accuracy is high, the geometry of the cut is good, and the cross-sectional shape of the cut presents a more regular rectangle.

Normally the laser cutting machine is equipped with multiple CNC control platforms, and the whole cutting process can all be realized by CNC. When operating, just change the CNC program, it can be applied to the cutting of different shape parts, which can be both two-dimensional cutting and three-dimensional cutting. Save the process adjust and program time.

The laser cutting is fast, take a 1200W laser cutting machine for example, the cutting speed can reach 600cm/min for a 2mm thick mild steel plate, and 1200cm/min for a 5mm thick polypropylene resin plate. The material does not need to be fixed by clamping when laser cutting, which can save both the fixture and the auxiliary time for loading and unloading.
