Choosing a CNC machine for metal cutting shouldn’t start with the question “Which machine is the best?”, but rather “Which solution will be best for my production?”. At STIGAL, we help you choose the technology that best fits your facility’s actual needs—we analyze not just the machine itself, but the entire process: from the type of material and parts, through the operator’s workflow, to subsequent stages such as welding, assembly, or bevel cutting.
The selection may include a fiber laser cutting machine, a laser for tubes and profiles, a CNC plasma cutting machine, an oxy-fuel cutting machine, a large-format machine, a 3D bevel cutting head, or a configuration tailored to individual requirements. The goal is not to sell just any machine, but to select a solution that will reduce unit costs, improve part repeatability, and increase the facility’s production capacity.
Selecting a CNC machine begins with an analysis of the production process
Every facility has different needs—the choice of machine differs for the batch cutting of thin sheet metal, for steel structures, and yet again for processing tubes, profiles, or large sheets. That is why, before we recommend a technology, we analyze what actually needs to be cut, in what quantities, and with what requirements. We take into account, among other things:
- type and range of material thickness (steel plates, tubes, profiles, structural sections),
- part dimensions and production batch sizes,
- the expected accuracy, repeatability, and edge quality,
- the need for further processing, bevel cutting, or chamfering,
- how to perform weld preparation on a workpiece,
- available space, loading methods, and automation capabilities,
- Planned production growth in the coming years.
As a result, the selection of a CNC machine is not based solely on the power of the drive or catalog specifications, but on whether a given configuration matches the actual operating conditions at the plant.
Fiber laser, plasma, gas, or a combination?
There is no single technology that is best for every application—the choice should be based on the process, not on a simple comparison of machines:
| Technology | Strengths | Typical Applications |
|---|---|---|
| Fiber laser cutting machine | precision, speed, repeatability, high-quality edges | steel plate cutting, mass production, precise details, reduced post-cutting machining |
| CNC plasma cutting machine | Good productivity with thicker materials | structural components, thicker steel plates, parts with acceptable plasma quality |
| CNC oxy-fuel cutting machine | Cutting very thick steel components | Large thicknesses where oxy-fuel technology is justified |
| Laser for Tubes and Profiles | Fewer operations, repeatability, ready for assembly and welding | tubes, profiles, structural sections |
This table is for illustrative purposes only—the best solution is determined by analyzing the specific production process.

Part Analysis, Cutting Tests, and Cycle Times
The most common mistake when choosing a machine is focusing on technical specifications without analyzing the actual details. However, the part itself should be the starting point—one solution will work for simple steel plate parts, another for parts with many holes or bevels, and yet another for profiles prepared for welding. That’s why we focus first and foremost on what parts will be produced by the machine and how they will be used afterward.
The selection process doesn’t have to be based on assumptions. At STIGAL, you can perform cutting tests on specific materials, thicknesses, and part types—to evaluate edge quality, process repeatability, and cutting time. We can also calculate approximate cutting times, taking into account the number of cuts, contour length, part layout on the sheet, process gas, and subsequent operations. This allows you to determine how a given machine will affect productivity and the unit cost of the part.
What are the benefits of a well-chosen machine?
A CNC machine is part of a larger process—it affects deburring, bevel cutting, welding, assembly, and order turnaround times. A well-chosen solution therefore supports not only the cutting process itself, but also the organization of work throughout the entire facility. In practice, it can help achieve:
- greater consistency in details and a more stable process,
- better edge quality and reduced need for additional processing,
- shorter weld preparation time for parts to be welded,
- better use of the material,
- more efficient organization of the operator’s work,
- greater flexibility and a wider range of workpieces,
- lower unit cost in certain applications,
- better prepare the plant for further growth.
The result depends on the machine’s configuration, the type of production, and how the technology is used—which is why it is advisable to begin the selection process with a technical consultation, a needs analysis, and, if warranted, cutting tests.
The STIGAL Team’s Experience and Support
STIGAL is a Polish manufacturer of CNC metal-cutting machines—our product line includes fiber laser cutting machines, lasers for tubes and profiles, CNC plasma and oxy-fuel cutting machines, large-format machines, and 2D and 3D solutions. Our team consists of people who have been with the company for over a dozen years or longer. Our specialists have analyzed a wide range of production scenarios—from simple cutting of steel plates to implementations for steel structures, tubes, profiles, and large-format applications.
This experience allows us to quickly assess which solution is appropriate and which would be overkill or insufficient—and to avoid mistakes that aren’t always obvious at the time of purchase: a work area that’s too small, mismatched technology, or a lack of features needed in the future. We want to ensure that the customer isn’t left to make the decision alone: we guide them from the initial consultation, through detailed analysis and cutting tests, all the way to selecting the right configuration and parameters.
How should I prepare for a consultation on choosing a machine?
To ensure the consultation is focused, it’s a good idea to prepare some basic information about the production process—it doesn’t have to be a complete set of technical specifications; often, a general description of the process is sufficient:
- types of cut materials and typical thicknesses,
- dimensions of sheets, tubes, or profiles,
- examples of details (drawings are welcome),
- expected productivity and current production issues,
- further procedures following the incision,
- available space in the hall and planned expansion.
If you have drawings of parts or sample components, we will use them to conduct a more detailed analysis—to select parameters, estimate cutting time, and recommend the most appropriate solution.

Dobór maszyny CNC powinien zacząć się od analizy produkcji: rodzaju materiału, zakresu grubości, typu detali, oczekiwanej jakości krawędzi, wielkości serii, dalszej obróbki oraz dostępnej przestrzeni. Dopiero na tej podstawie można wskazać odpowiednią technologię i konfigurację maszyny.
Tak. W wielu przypadkach można wykonać testy cięcia, aby sprawdzić jakość krawędzi, powtarzalność procesu, czas wykonania detalu i dopasowanie technologii do konkretnego materiału. Testy pomagają ocenić, jak dane rozwiązanie sprawdzi się w produkcji klienta.
W określonych przypadkach można przeanalizować orientacyjne czasy cięcia dla konkretnych detali, materiałów i grubości. Takie obliczenia pomagają ocenić wydajność procesu oraz lepiej dobrać technologię i konfigurację maszyny.
To zależy od zastosowania. Laser fiber sprawdza się tam, gdzie ważna jest precyzja, powtarzalność, szybkość i wysoka jakość krawędzi. Przecinarka plazmowa CNC bywa dobrym wyborem przy zastosowaniach konstrukcyjnych i cięciu grubszych materiałów. Wybór powinien wynikać z analizy produkcji, a nie tylko z porównania technologii.
Tak. Dobór rozwiązania może uwzględniać konkretne detale, materiał, grubości oraz wymagania dotyczące jakości krawędzi, spawania, montażu i dalszych operacji. Jeżeli klient posiada rysunki lub przykładowe detale, można wykorzystać je do dokładniejszej analizy.
Tak. Konsultacja technologiczna pozwala uporządkować wymagania i dobrać maszynę do realnych potrzeb zakładu. Dzięki temu można uniknąć zarówno zbyt słabej konfiguracji, jak i inwestycji w funkcje, które nie będą wykorzystywane w produkcji.
