Choosing a laser cutting machine requires comprehensive consideration of factors such as your own processing needs, material characteristics, and budget, avoiding blind pursuit of parameters or brands. Here are the key purchasing points, which can be screened step by step according to priority:

I. Clarify core needs: What to process? What is it used for?

1. Processing materials

• Metal materials: Priority is given to fiber laser cutting machines (wavelength 1064nm, high absorption rate for metals, suitable for metals with a thickness of 0.5-20mm; high-reflectivity materials such as copper and aluminum require high-power models).

2. Processing format

Choose the machine table according to the maximum size of the processed workpiece to avoid "using a large machine for small materials" or "using a small machine for large materials" . Small batches of small parts choose small formats, and industrial mass production choose large formats.

3. Accuracy and speed requirements

• Precision parts : Priority is given to positioning accuracy (≤0.03mm) and repeat positioning accuracy (≤0.01mm). Choose high-rigidity machine beds  and servo motors.

• Mass production : Focus on cutting speed , but it is necessary to balance speed and cut quality.

II. Core parameters: Power, laser, control system

1. Laser power

• Power determines cutting thickness and efficiency, and needs to match the material:

• Metal cutting: For low-carbon steel/stainless steel ≤3mm, choose 500-1000W; for 3-10mm, choose 1500-3000W; for more than 10mm, 5000W+ is required .

• Note: High power is not universal. Using high power for thin materials may cause thermal deformation, so it should be chosen according to needs.

2. Laser brand

The laser is a core component, directly affecting stability and service life:

• Fiber lasers: For imports, choose IPG, Raycus, Maxphotonics; domestic ones have matured in technology in recent years, with high cost performance, suitable for small and medium batches.

3. Control system

It affects operational convenience and cutting accuracy. Priority is given to systems that support CAD graphics import, automatic typesetting, and breakpoint continuation (such as Weihong, Baichu; domestic systems have high cost performance and simple operation; imports such as Germany's PA are suitable for high-end precision needs).

III. Equipment configuration: Details determine stability

1. Machine bed structure

The machine bed carries cutting components and needs to be resistant to deformation and vibration:

• Small machines: Welded steel structures.

• Industrial grade: Cast iron machine bedsor overall welded and aged machine beds (balancing rigidity and cost).
