Cutting Processes
Fiber laser metal cutting machines are versatile tools that can perform various metal cutting processes, including cutting, drilling, and engraving. These processes enable users to achieve high precision and quality in their workpieces.
Cutting Process
Cutting is one of the most common processes performed using fiber laser metal cutting machines. It involves cutting through metal sheets and plates with high precision and accuracy. The cutting process can be used to cut various types of metals, including stainless steel, aluminum, and titanium.
| Process | Description | Typical applications |
| Cutting | Cutting through metal sheets and plates | Aerospace, automotive, shipbuilding |
| Drilling | Creating holes in metal sheets and plates | Aerospace, automotive, medical equipment |
| Engraving | Creating engravings and patterns in metal surfaces | Signage, decorative items, precision instruments |
The cutting process is based on the principle of ablation, where the laser beam removes material from the workpiece through a process of vaporization. The laser beam heats the metal to a high temperature, causing it to vaporize and be blown away by a gas jet.
Ablation and Vaporization
Ablation and vaporization are two related processes that occur during the cutting process. Ablation refers to the removal of material from the workpiece through a process of vaporization. Vaporization, on the other hand, refers to the transition of a liquid to a gas state. In the context of fiber laser metal cutting, vaporization is the process by which the laser beam heats the metal to a high temperature, causing it to vaporize and be blown away by a gas jet.
Role of Assist Gases, Fiber laser metal cutting machine
Assist gases play a crucial role in the cutting process. They are used to blow away the vaporized material and improve the cut quality. The most commonly used assist gases are nitrogen, oxygen, and air. The choice of assist gas depends on the type of metal being cut and the required cut quality.
The assist gas is also used to protect the workpiece from oxidation and contamination. For example, when cutting stainless steel, a nitrogen gas jet can be used to prevent oxidation and achieve a high-quality cut.
The choice of assist gas is critical in achieving a high-quality cut. The wrong choice of assist gas can lead to a poor cut quality or even damage to the workpiece.
Safety Precautions
When operating a fiber laser metal cutting machine, safety should be the top priority. Fiber laser machines emit a high-intensity beam of infrared radiation, which can cause serious eye damage and skin burns if not handled properly. In addition to the risk of eye damage, there is also a fire hazard due to the high-temperature cutting process. Therefore, it is essential to take all necessary precautions to ensure a safe working environment.
Personal Protective Equipment (PPE)
Operating a fiber laser metal cutting machine requires the use of personal protective equipment (PPE) to prevent eye damage and skin burns. The PPE should include:
- Protective eyewear: This includes laser safety glasses or goggles that have a shade of at least 5 and are designed to block out 99.9% of the infrared radiation.
- Heat-resistant gloves: These gloves protect the hands from heat and flames, providing an additional layer of protection.
- Fire-resistant clothing and long-sleeved shirts: These protective garments prevent burn injuries and protect the skin from flames.
- Steel-toed safety shoes: These shoes protect the feet from heavy objects and tools.
Machine Safety Features
In addition to the PPE, fiber laser metal cutting machines are equipped with various safety features that prevent accidents. Some of these features include:
- Interlocks: These are electrical switches or mechanisms that prevent the machine from starting if the door or cover is not properly closed or if the operator is not wearing the required PPE.
- Emergency stops: These are buttons or panic stops that allow the operator to quickly shut down the machine in case of an emergency.
It is essential to understand the operation and functioning of these safety features to ensure the safe operation of the machine.
