CNC fiber laser cutting machines are incredible devices that can cut a variety of materials with precision and speed. The power range you mentioned, from 1000W to 30000W, indicates the power capacity of these machines. The following is a detailed analysis:

1000W to 2000W: These are suitable for thinner materials such as sheet metal, stainless steel, carbon steel and aluminum. They offer high precision and are commonly used in industries such as signage, electronics and automotive for complex cutting tasks.
2000W to 6000W: As power increases, these machines can cut thicker materials and faster speeds. They are commonly used in industries such as aerospace, manufacturing and construction where thicker metals need to be machined efficiently.
6000W to 12000W: This range is ideal for heavy-duty industrial applications. They cut through thick metal effortlessly and are often used in shipbuilding, heavy machinery manufacturing, and structural steel fabrication.
12000W+: These high-power machines are used for extremely thick materials and heavy-duty industrial applications. They can cut thick steel plates with ease and are used in industries such as shipbuilding, oil and gas, and heavy equipment manufacturing.
Each power range offers different functions suitable for various applications. When selecting a CNC fiber laser machine, you must consider the specific requirements of your project, including material type, thickness, and desired cutting speed, to select the most appropriate wattage range.
