1. Fanuc: Stable, Hassle-Free, Easy to Maintain
Fanuc's equipment in China and Southeast Asia, especially in the automotive parts, molds, circuit boards and these industries. Its characteristics are quite distinctive:
- Stability. You hardly ever hear of Fanuc servo motors breaking down inexplicably. Most problems are sensors, wiring, or human error.
- Module unification. The interface between the controller, drive, motor is very regular, debugging is also relatively smooth.
- Programming is simple. Many front-line maintenance personnel to start Fanuc very quickly, learn the basic parameter settings can handle most of the problems.
Songwei has its own Fanuc test platform, each repair will simulate the working conditions to run a round, to ensure that there is no problem before shipment.
2. Siemens: Powerful, High-End, And Technically Demanding
Siemens equipment is more commonly found in local European machine tools, or in factories that do complex 5-axis, high-precision machining, such as high-end machine tool brands from Switzerland, Germany, and Italy.
Its advantages are obvious:
- Strong software system. For example,
TIA Portal and SINUMERIK ONE can integrate PLC, HMI, and drive together, which is suitable for digital factory.
- Flexible configuration. Multi-axis machining and various feedback protocols can be adapted, but the corresponding configuration complexity is also high.
- Functionality is strong, but the threshold is also high. Adjustment parameters, diagnose problems often use official software, maintenance threshold is also higher than Fanuc.
Songwei also has a corresponding Siemens test platform, especially the SINAMICS series, many customers look for us in order to bypass the original factory's ridiculously high maintenance offer.
3. Are Parts Easy to Find?
Fanuc's spare parts circulation is very large, especially used and refurbished, no matter in China, Vietnam, Thailand or the United States, basically can be found. Siemens parts are relatively more expensive, and some models of material in Asia is not easy to find.
On our side, we have spare parts for both systems, Fanuc's common models are directly in stock, and Siemens' we can also quickly transfer from Europe.
4. Cost and Maintenance
Fanuc's overall cost of ownership is low, and when things go wrong, many factories have their own engineers on hand to take care of the problem. Siemens' systems break down, and usually require specialized repairs or official intervention, so naturally the maintenance costs are high.
But then again, if your project is all about extreme precision and complex machining, Siemens is really the better choice.
5. Typical Preferences in Different Industries
Among the customers we have been in contact with for a long time, the general selection tendency is as follows:
- Automotive industry: Fanuc
- Mould and die machining: Fanuc
- High-end automation line: Siemens
- European original equipment: Siemens
- Consumer electronics: Fanuc
- System integration/production line outsourcing: Siemens
To Summarize: What Suits You Is the Best
Fanuc is for factories that want stability, peace of mind, and fast deployment; Siemens is for customers who are looking for ultimate flexibility and future digitalization capabilities.
We at Songwei are not biased towards any brand, we just look at which one suits your situation. If you are not sure, just send a picture, say the parameters, we will give you advice, recommend the right parts or alternative programs. Maintenance, commissioning, supporting selection,
leave it to us.
