Fiber Laser Cutting Machines in Cutting Carbon Steel

Currently, fiber laser users are the most concerned about how to improve efficiency and reduce cost, fiber laser cutting machines with ideal cutting speed, low deformation and high precision have become common cutting products in a short time. The high-power laser source significantly improved the processing efficiency, the thin plate cutting speed approached the mechanical performance control limit, and the thick plate cutting also experienced many breakthroughs.

Carbon steel is mainly a common alloy formed of iron and carbon. Carbon accounts for 0.02%-2.11% of its total mass. Carbon steel also contains elements such as silicon, manganese, sulfur and phosphorus. In theory, the higher the proportion of carbon, the higher the hardness and strength of the entire alloy, but the lower the plasticity.

The advantages of fiber laser cutting machine in cutting carbon steel are reflected in many aspects. First of all, the cut quality is good, the cutting surface is smooth and does not need to be reworked. Second, the cutting speed is fast, which greatly improves the working efficiency. In this way, the output power is stable, the laser light source has a long service life, and the maintenance is simple. Another advantage is the powerful software function. Using this software, users can design various graphics and text, and the software is easy to operate.

For the processing of carbon steel, the most important part is to ensure precision, especially for hardware parts used in automobiles, ships, precision accessories and household appliances. Low cost and high efficiency are the pursuit of more and more customers. The workforce is getting smaller and smaller, and automation and smart devices are gradually becoming the mainstream, therefore, laser devices which can save physical labor and improve efficiency will surely gain the attention of the market.

how to choose the best speed to cut materials?

The laser power will affect the cutting speed, and the cutting speed of laser cutter will affect the cut quality of the board. Under certain laser power conditions, there is an optimum cutting speed range. Avoid cutting too fast or too slow, and keep a proper processing speed, otherwise it will affect the smoothness of the cutting material.

Cutting speed is too fast

1. When the laser beam and the material are in contact with each other, the material may be damaged and the cutting will fail.

2. The cutting area is not accurate, and it may only cut to certain areas, causing other areas to be ignored.3. The entire cutting surface will be laminated.

4. As a result, the board cannot be cut in time, the surface of the cut section has diagonal lines, and the bottom of the board will generate slag.

Cutting speed is too slow

1. The interaction time between the material and the laser is increased, resulting in excessive melting of the cutting board and rough surface of the cut part.

2. The slit will be widened accordingly, which will cause excessive burn on the small rounded or sharp corners, and the ideal cutting effect cannot be obtained.

3. Low cutting efficiency affects the production capacity.

Cutting speed judgment method

1. Appropriate cutting speed: the cutting sparks propagate from top to bottom, the cutting surface is stable, and there is no slag at the bottom;

2. The cutting speed is too fast: the cutting sparks are tilted;

3. The cutting speed is too slow: the cutting sparks are not diffused and rarely, and will condense together.
