3KW fiber laser cutting machine has been widely used in the metal processing industry for its high efficiency, high precision and wide material applicability. However, to give full play to the performance of 3KW laser cutting machine and obtain high-quality cutting effect, fine adjustment of parameters is essential.
This article will deeply explore of 3kw fiber laser cutting parameters setting to help you optimize the cutting process.
Parameters of 3KW fiber laser cutting machine
- Power: The power of 3KW laser is generally between 2800W-3200W, and the cutting depth can be controlled by adjusting the output power.
- Speed: Cutting speed affects cutting efficiency and quality. Too fast may cause uneven cuts, while too slow will reduce production efficiency.
- Focal position: The focal position has an important influence on the flatness of the cut and the heat-affected zone.
- Pulse frequency: Affects cutting speed and material surface quality.
- Auxiliary gas: Different auxiliary gases are selected for different materials, such as oxygen, nitrogen, argon, etc.
- Cutting head height: The distance between the laser head and the workpiece affects the focal position and cutting effect.
Cutting parameters for different materials
- Carbon steel: When cutting carbon steel, oxygen is used as the auxiliary gas to assist cutting through oxidation reaction. The power and speed can be adjusted according to the material thickness.
- Stainless steel: When cutting stainless steel, nitrogen or argon is used as the auxiliary gas to prevent material oxidation. The cutting speed is relatively slow to ensure the cutting quality.
- Aluminum alloy: When cutting aluminum alloy, nitrogen is used as the auxiliary gas. Due to the good thermal conductivity of aluminum alloy, the cutting speed can be relatively fast.
- Other materials: Copper, brass, etc., the cutting parameters need to be adjusted according to the specific characteristics of the material.
