What is laser cutting machine and how does it work?

Laser cutting machine uses a laser as its heat source and can be classified into sheet cutting and tube cutting. This includes sheet laser cutting machines, tube laser cutting machines, and sheet & tube combo machines, making it one of the most advanced metal processing technologies available today.

The laser cutting machine focuses a high-density laser beam to convert laser energy into heat. This localized heat causes the material to melt, burn, or vaporize. The melted or vaporized material is then blown away by a gas flow, achieving precise cutting.

Laser cutting machines can cut a wide range of materials, including stainless steel, carbon steel, alloy steel, silicon steel, aluminum, aluminum alloy, galvanized sheet, aluminum-zinc plate, pickled sheet, titanium, and other metal sheets.

These machines are used across many industries, such as sheet metal working, kitchenware, aerospace, electrical cabinets, household kitchenware, automotive parts, construction machinery, agricultural machinery, and more.

When selecting a laser cutting machine, we recommend focusing on the following 10 key factors:

  • Laser power

  • Cutting speed

  • Cutting accuracy

  • Type of laser generator

  • Degree of automation and software

  • Ownership costs

  • Material compatibility

  • Technical support and service

  • Installation space and requirements

  • Environmental and safety factors

The power of a fiber laser directly impacts its cutting capabilities. Fiber lasers with varying power levels are designed to handle different material thicknesses and types. Below is an overview of the cutting capacities for fiber lasers across the main power ranges:

  • 1.5kW Fiber Lasers: Suitable for cutting thin sheets of stainless steel, carbon steel, and aluminum (up to 6mm thickness).

  • 3-6kW Fiber Lasers: Ideal for medium-thickness materials (up to 12mm for stainless steel, 16mm for carbon steel).

  • 8-12kW Fiber Lasers: Perfect for cutting thicker sheets (up to 20mm for stainless steel and 25mm for carbon steel).

  • Above 15kW Fiber Lasers: Used for heavy-duty cutting, capable of handling the thickest metals (up to 40mm or more for stainless steel and 50mm for carbon steel).

Each power range offers different cutting speeds, with higher power lasers providing faster cutting speeds and greater precision for thicker materials.

Proper maintenance of a laser cutting machine is essential to ensure optimal performance and longevity. Here are some key points to consider:

  • Regular cleaning: Keep the machine and surrounding area clean to prevent debris and dust buildup, which can affect performance.

  • Check laser optics: Inspect the lenses and mirrors regularly for dirt, cracks, or damage. Clean them using appropriate methods to maintain cutting precision.

  • Cooling system maintenance: Regularly check the water chiller or cooling system to prevent overheating and ensure the laser operates at the correct temperature.

  • Inspect gas flow: Ensure the cutting gas is being supplied at the correct pressure and quality. Low-quality gas or inconsistent pressure can affect cutting quality.

  • Monitor mechanical components: Lubricate moving parts and check for wear on the rails, gears, and motors. Proper lubrication helps maintain smooth and precise operation.

  • Calibration and alignment: Perform periodic calibration and alignment checks to ensure the laser and cutting head are functioning correctly.

  • Software updates: Keep the machine’s software and firmware up to date for better performance, improved functionality, and enhanced security.

Regular maintenance helps prevent downtime, extend the life of your machine, and ensure consistent cutting quality.

Laser cutting offers several advantages over traditional cutting methods, including:

  • Non-contact cutting: The mechanical parts of the laser cutting head do not touch the workpiece, preventing surface scratches during operation.

  • High speed and precision: Laser cutting is fast, with smooth, flat edges that typically require no further processing.

  • Minimal heat-affected zone: The heat-affected zone is small, resulting in minimal deformation of the sheet and narrow cutting seams (0.1-0.3mm).

  • No mechanical stress or shear burrs: Cuts are free from mechanical stress and shear burrs, ensuring high-quality edges.

  • High precision and repeatability: Laser cutting provides excellent cutting precision and repeatability, without damaging the material surface.

  • Flexible processing and no need for molds: CNC programming allows for the processing of any flat pattern, enabling the cutting of large entire sheets without the need for molds, saving both time and costs.

Laser cutting is gradually improving and replacing traditional metal cutting processes, offering more efficient and versatile cutting solutions.

What is laser welding machine and how does it work?

Laser welding machine is a device used to weld materials with high precision and efficiency. It features high power density and rapid energy release, making its welding efficiency far superior to other traditional welding methods. Whether welding the same or different types of materials, there is usually no need for secondary treatment after welding, representing a significant advancement in welding technology.

Laser welding works by using a high-energy laser beam to locally heat small areas of materials. The energy from the laser radiation quickly spreads into the material via thermal conduction, melting the material to form a molten pool that serves as the basis for welding.

Laser welding can achieve various types of welding, including:

  • Butt welding

  • Overlay welding

  • Stitch welding

  • Stud welding

  • T-joint welding

  • Internal & external corner welding

  • Seal welding

Laser welding offers numerous advantages, such as deep welding depth, narrow weld width, a small heat-affected zone, minimal material deformation, and fast welding speed, making it ideal for high-precision applications.

Laser welding uses a laser beam as a heat source, making it highly effective for welding thin-walled materials and precision parts. The main materials welded include:

  • Stainless steel

  • Carbon steel

  • Mold steel

  • Copper

  • Aluminum

  • Gold

  • Silver

In addition to welding, laser welding is also used for repairing defects such as wear, pores, sand holes, cracks, scratches, deformation, and reduced hardness in workpieces, providing a versatile solution for both manufacturing and repair applications.
