The CNC machining center is a high-precision CNC machine tool. The CNC system is the core control center of the entire machining center, which is equivalent to the human brain and its importance is self-evident. The numerical control system issues orders through a series of electronic components and circuits all over the machine tool, and then completes the various processing procedures of the machine tool. my country's CNC technology has been developing rapidly in the past ten years, and the domestic CNC system for machining centers has occupied a certain market share. As far as the current domestic machining center market is concerned, the CNC systems used in high-end mid-range models still need to be imported. The CNC system is highly technical, and there are many technical barriers. There are not many good CNC system suppliers in the world, and Siemens and FANUC are undoubtedly the two giants of CNC system for machining centers with the largest market share.

 

In fact, the operating principles of Siemens CNC system and FANUC system are almost too many, and the operation interface, function matching, and programming methods are slightly different. Next, Yuange will give you a detailed introduction to these two imported CNC systems.

 

 

 

 

 

FANUC CNC System

 

Background

 

FANUC is a professional CNC manufacturer in Japan and the world's largest professional manufacturer of CNC devices. The earliest application of CNC system to machine tool equipment has made outstanding contributions to the development of world industrial automation. Siemens is a global enterprise in the field of electrical and electronic engineering. Siemens CNC is a department of the company. Siemens and FANUC also design other product areas, such as FANUC robots and Siemens appliances. It has nothing to do with our machining center industry, so I won't repeat it here.

 

 

 

 

 

 

 

Siemens CNC System

 

Grid requirements

 

FANUC systems generally use isolated power supplies, from three-phase 380V to 200V. The SIEMENS numerical control system is 380V mains. In contrast, the FANUC system is more suitable for the current grid requirements of our country. A major requirement of the Siemens CNC system is the high power grid requirements, which is not suitable for the current domestic power grid conditions.

 

development level

 

Siemens' numerical control has a relatively high level of development and has achieved channel control. But it is not very stable. Friends who configure imported Siemens CNC system must know that PLC crash or program loss of Siemens CNC system is one of the common faults in maintenance. However, FANUC's PLC program has better stability and generally does not crash. Unless the system fails, there is generally no program loss. If you don't want to engage in low-level work, want to get rid of the status quo, want to learn UG programming


 

Getting started

 

The operating system should comprehensively consider the programming situation, ease of use and ease of learning. Take common metal cutting operations as an example, there is not much difference in programming between the two. G code and M code are still the most important programming methods. In terms of ease of use, the Siemens CNC system is even better. Even if the user has no common knowledge of workpiece technology and programming foundation, he can still use the shopmill function and graphic programming function to complete the programming process. In terms of ease of learning, the FANUC panel has many functions and is difficult to master. Must remember the key name and function. Siemens is relatively easy, only three keys can be operated, the rest can be completed by the screen prompts.

 

In this actual use situation, the current domestic machining center imported CNC system market uses slightly more FANUC systems than Siemens. These two CNC systems can basically represent the highest level of currently imported CNC systems!
