Question 1: What operating systems are there for CNC lathes? When they were installed in the past, the first one used in China was Guangzhou CNC (gsk), the second was Beijing KND (KND), and the ones with less usage were at the back. Nanjing Huaxing, Nanjing Renhe, Beijing Aerospace, Hangzhou Zhengjia, and many unknown ones are rarely used and their performance is not very stable
The commonly used ones abroad are Japan's Fanuc, Mitsubishi, Omori, and Germany's Siemens
It depends on your machine tool function and price/performance requirements to select the system
Domestic ones are all similar, while foreign ones have higher precision and function requirements
Question 2: The systems of CNC machine tools are all Which ones are there? Germany's Siemens and Heidenhain, Spain's Fagor, Japan's Fanuc and Mitsubishi, there are many domestic ones but they are all low-end, such as Guangshu, Beijing Kanedi, Shanghai Kaifang, Wuhan Huazhong and Huaxing, Chengdu Guangtai, Shenzhen Shanxing, Aerospace Century Star, etc. Some other well-known machine tool manufacturers have their own company-specific systems, such as Haas and Heco in the United States, and more in Japan, such as Mazak, Makino, Okuma, Brother etc!
Question 3: What types of CNC machine tool systems are there? (1) Traditional special-purpose CNC systems
The hardware of this type of CNC system is developed by the CNC system manufacturer itself and has strong special-purpose capabilities. After a long period of use, the quality and performance are stable and reliable, and currently occupy most of the manufacturing market. However, because it adopts a completely closed system structure, it often has the following shortcomings:
a. User application, maintenance and operator training are completely dependent on the CNC system manufacturer, and the system maintenance cost is high;
b. The expansion and update of system functions completely depend on the company’s technical level, and the cycle is relatively long;
c. A large number of commercially available cheap general-purpose software and hardware cannot be used on dedicated CNC systems. The function is relatively simple.
Therefore, with the continuous development of open architecture CNC systems, the market of this traditional dedicated CNC system is being challenged, and the market share has been gradually reduced.
(2) Open CNC system with PC embedded in NC structure
Such as FANUC16i/18i, Simens840D, NumIO60 and other CNC systems. Compared with traditional special-purpose CNC systems, this type of CNC system has some openness in structure and is very powerful. However, the system software and hardware structure is very complex, and the system price is also very expensive. Generally, small and medium-sized CNC machine tool manufacturers do not have the economic ability to Buy.
(3) Open CNC system with NC embedded in PC structure
The hardware part of this CNC system is composed of an open architecture motion control card and a PC. Motion control cards usually use high-speed DSP as the CPU and have strong motion control and PLC control capabilities. For example, Japan's MAZAK Company uses Mitsubishi Electric's MELDASMAGIC 64 to construct MAZATROL 640 CNC. This kind of CNC system has better openness and is more convenient to improve functions. The control function of the system is mainly realized by the motion control card. When the machine tool hardware changes, only the corresponding part of the control software needs to be modified, and the system is cost-effective. It is relatively high and can meet the needs of most CNC machine tool manufacturers.
(4) Full software open CNC system
This is the latest open architecture CNC system. All CNC functions (including interpolation, position, etc.) Control, etc.) are all implemented by computer software. Compared with the previous CNC systems, the all-software open CNC system has the highest cost performance and therefore the most vitality.
Question 4: What operating systems are available for CNC lathes? The CNC operating systems I know include FANUC CNC system; SIEMENS CNC system; Huazhong CNC system; Century Star CNC system; Mitsubishi CNC system, etc.
The FANUC CNC system is relatively stable, while the operation interface of the SIEMENS CNC system is relatively friendly and easy to use.
Question 5: What is a CNC machine tool? CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions and decode them to make the machine tool move and process parts.

When several feeds are linked, the processing of positioning, straight lines, plane curves and space curves can be completed.
●Auxiliary devices refer to some necessary supporting components of CNC machine tools to ensure the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC dividing heads, as well as cutting tools and monitoring and detection devices.
