What to Consider When Purchasing a Laser Cutter?

What Materials Do You Need To Cut?

When choosing a fiber laser cutting machine, the primary consideration is the material to be cut. Fiber laser cutting machines can cut various types of metals, including carbon steel, stainless steel, galvanized sheet, aluminum, titanium, copper, and brass, among others. Non-metallic materials should be processed using a CO2 laser cutting machine.

What is the size of your workpiece?

The larger the working area of the laser cutting machine, the larger the size of the workpiece it can accommodate. This is crucial for applications that require processing large-sized materials. Factors such as the size, structure, and material of the worktable affect the cutting results. Note that with an increase in the size of the worktable, the size and price of the cutting machine will also correspondingly increase.

Cutting Thickness

The power of the cutting machine limits the depth of cut, so you need to choose the right model, tool, etc. according to the actual needs. As the thickness of the material increases, a more powerful machine is needed, and accordingly, the price of the machine will increase.

Cutting Accuracy

Cutting accuracy is a key consideration, which determines the error in the size of the parts cut out. The cutting accuracy of the laser cutting machine mainly depends on the quality of the laser source, the stability of the optical system, the stability of the table, the CNC system and other components and parameter configuration. According to the actual needs and cost considerations, choose the appropriate model of cutting machine. Roc laser has a variety of models of fiber laser cutting machine, different cutting machine models corresponding to different configurations, customers can match the machine model according to the processing accuracy requirements.

Control System

The control system is directly related to the operability and stability of the CNC laser cutting machine. Mainstream control system brands such as CypCut, Lantek, etc., when choosing the need to consider the ease of use, functionality and compatibility with other equipment.

Higher Power Provides Greater Flexibility

The choice of laser power is based on the needs of the material and content to be cut. Different power levels are required for different materials and processes. For example, cutting acrylic and plastics, glass may not require excessive power, while cutting metal materials may require a laser power of at least 1000W. Thicker materials typically require higher power levels to ensure effective perforation and cutting. The most popular choices today are in the 6-12KW range, and the higher KW used does not necessarily mean greater thickness cutting capability, but rather higher linear cutting speeds. DP Laser can provide high power industrial laser cutting machines from 20kw~30kw.

Optical Components

To improve the cutting accuracy and effectiveness of a laser cutting head, it is necessary to consider factors such as wavelength, semi-reflective mirrors, fully reflective mirrors, refractive mirrors, etc., and to select high-quality optics suitable for the laser cutter. The combination of these key considerations ensures that the selected laser cutter meets real-world needs and delivers superior performance.

Lens Focal Length

Depth of cutting and speed: The choice of lens focal length directly affects the laser’s focal position on the surface of the workpiece. The right focal length ensures that the laser produces enough energy inside the workpiece to increase the depth of cut. However, a focal length that is too long or too short may result in insufficient energy or over focusing, affecting the cutting effect.

Cutting quality: Proper selection of the focal length improves the quality of the cut and avoids problems of excessive melting, burning or non-smooth cutting edges. By adjusting the focal length, the distribution of laser energy on the workpiece can be optimized to achieve a more precise and smooth cutting effect. The quality of the cut is directly related to the appearance and performance of the final product and is therefore another key factor in focal length selection. When cutting materials of different thicknesses, the laser lenses can be replaced with different focal lengths accordingly.

Safety Protection Devices

Be sure that the cutting machine you purchase is equipped with the necessary safety protection devices, such as safety guards and emergency stops. These devices are essential for maintaining staff safety. In addition, consider optional auxiliary production systems such as automatic loading and unloading systems and robots to improve productivity.

Cutting Type of CNC Laser Cutting System

Sheet Metal Laser Cutter has cutting classifications such as vaporization, melting, and oxidation. The choice of cutting method usually depends on the material and thickness of the workpiece, as well as the processing requirements. Different cutting methods have some differences in terms of accuracy, speed, and applicability. Different cutting methods can be selected based on different materials.

1. Laser vaporization cutting.

The use of high-energy, high-density laser beam to heat the workpiece, increase the temperature, so that the material in a short period of time vaporized into water vapor. Since the heat of vaporization is generally greater for materials, a high-power laser beam is required. Laser vaporization cutting is generally used for very thin metallic and non-metallic materials.

2. Laser melting cutting.

The material is heated to a certain temperature so that it melts, and then a non-oxidizing gas is blown through a nozzle coaxial to the beam, using the pressure of the gas to expel the liquid metal and form a kerf. The energy required is only 1/10th that of vapor cutting, and it is not necessary to vaporize the metal completely. Materials generally suitable for laser fusion cutting include stainless steel, titanium, aluminum and its alloys, which are not easily oxidized materials or active metals.

3. Laser Oxygen Cutting.

The laser is used as a preheating heat source, and oxygen and other active gases are used as cutting auxiliary gases. After the gas is ejected, an oxidizing reaction occurs with the metal, releasing a large amount of oxidizing heat and forming a cut. Materials generally suitable for laser oxygen cutting include carbon steel, titanium steel, heat-treated steel and other easily oxidized metal materials.

Reliability and quality of service

Before purchasing a laser cutting machine, in addition to the type of cutting, you should also pay attention to the manufacturer’s after-sales service. Experienced cutter manufacturers usually provide a perfect after-sales service system, it is recommended to visit the factory before purchase to ensure that the selected cutter can meet the actual needs.
