Laser cutting is one of the most common processes in modern sheet metal fabrication.
From machine components and equipment enclosures to machine tools, automation equipment and semiconductor equipment parts, many sheet metal components begin with laser cutting.
However, laser cutting is not simply about “cutting the sheet.” Material type, sheet thickness, part geometry, hole size, cutting parameters and equipment conditions can all affect the final result.
So, how does laser cutting work, and what factors affect cutting quality?
Below, we explain the basic process, equipment, materials, quality factors and common applications of fiber laser cutting.
Laser cutting uses a high-energy laser beam focused on the surface of a metal material. The concentrated energy melts or vaporizes the material locally, while assist gas removes the molten material to create the required cutting profile.
Compared with traditional mechanical cutting, laser cutting can follow CAD or engineering drawing geometries and is suitable for producing sheet metal parts with different shapes, holes and complex profiles.
Common applications include:
One of the most common laser technologies used for metal sheet fabrication today is fiber laser cutting.
Fiber laser systems transmit laser energy through optical fiber and focus the beam onto the processing area for cutting.
For metal sheet processing, fiber lasers offer characteristics such as fast processing, efficient energy transmission and suitability for a wide range of metal materials.
Actual cutting performance still depends on material type, sheet thickness, part geometry, cutting parameters and equipment conditions.
Chuangpu Technology uses an AMADA ENSIS-3015AJ fiber laser cutting machine for sheet metal laser cutting.
The maximum processing area is:
3,070 × 1,550 mm
Actual cutting conditions are adjusted according to material type, sheet thickness, part geometry and fabrication requirements.
For machinery and equipment manufacturers, laser cutting is not only about speed. Cutting quality, dimensional stability and compatibility with subsequent bending, welding and assembly processes are also important.
Even when using the same laser cutting machine, different processing conditions can produce different results.
Common factors include:
Laser cutting is therefore not simply a matter of setting one cutting speed.
Processing parameters need to be adjusted according to the material and thickness to achieve an appropriate balance between processing efficiency, cutting quality and dimensional stability.
Different metal materials have different physical characteristics, so different processing conditions may be required for laser cutting.
Common sheet metal materials include:
For example, stainless steel and carbon steel have different material characteristics during cutting, so laser parameters and assist gas conditions may also differ.
When requesting a laser cutting quotation, procurement teams should clearly specify the material type and sheet thickness together with the drawing.
Yes.
Sheet thickness is an important factor when evaluating laser cutting.
For the same material, moving from thin sheet to thicker material can affect cutting speed, processing parameters, heat effects and cutting quality.
When requesting a quotation, it is useful to provide complete information such as:
SUS 304, 1.5 mm thickness
SPCC, 2.0 mm thickness
If different parts use different thicknesses, it is also helpful to list them separately for evaluation.
Not necessarily.
Cutting speed is not the only consideration in laser cutting.
Overly aggressive cutting speeds may affect cutting quality, while cutting too slowly can reduce overall production efficiency.
Actual processing conditions should be adjusted according to material type, sheet thickness, part geometry and fabrication requirements to balance speed, cutting quality and process stability.
For B2B sheet metal fabrication, consistently producing parts that meet drawing requirements is generally more important than simply pursuing the fastest cutting speed.
If the cutting conditions are not properly balanced, the cut edge may develop burrs, dross or an uneven cutting surface.
Potential factors include:
Stable laser cutting quality therefore depends not only on the equipment, but also on proper parameter settings and process control.
Laser cutting can be used for many types of sheet metal components.
Examples include:
If the component requires subsequent bending or welding, laser cutting can serve as the first stage of the overall sheet metal fabrication process.
Laser cutting is often only one step in the sheet metal fabrication process.
Depending on the component requirements, subsequent processes may include:
Laser Cutting → Press Brake Bending → Welding → Grinding → Surface Treatment → Assembly
For example, an equipment enclosure may first be laser cut, then bent into a three-dimensional structure, followed by welding and other secondary processing.
When requesting a laser cutting quotation, it is therefore useful to provide any known secondary processing requirements at the same time.
When requesting laser cutting services, it is recommended to provide at least:
The more complete the information, the easier it is for the fabricator to evaluate the manufacturing process and quotation.
If only a 3D CAD file is currently available, it can also be provided as a starting point for understanding the part structure and discussing fabrication requirements.
