When purchasing a CNC machining center, the same machine tool body can be equipped with multiple CNC systems. Among the available systems, the performance level varies greatly, which directly affects the equipment price composition.

At present, the types and specifications of CNC systems are extremely diverse. The imported systems mainly include FANUC from Japan, SINUMERIK from Germany, MITSUBISHI from Japan, NUM from France, FIDIA from Italy, FAGOR from Spain, and A-B from the United States.

The domestically produced systems mainly include Guangzhou System, Aerospace System, Central China System, Liaoning Blue Sky System, Nanjing Dafang System, North Kaiqi System, Tsinghua System, KND System, etc. Each company has a series of products of various specifications. The basic principles to reduce the risk of CNC system selection are: high performance-to-price ratio, convenient use and maintenance, and long market life of the system.


Therefore, we cannot one-sidedly pursue high-level and new systems. Instead, it should focus on the performance of the host, make a comprehensive analysis of system performance and price, and select a suitable system. At the same time, the traditional closed architecture numerical control system or PC embedded NC structure numerical control system should be gradually reduced, because the function expansion, change and maintenance of this kind of system must rely on the system supplier.


The open CNC system with NC embedded in PC structure or SOFT structure should be used as much as possible. The CNC software of this type of system is all installed in the computer, and the hardware part is only the standardized general interface between the computer and the servo drive and the external 1/O. Just as various brands of sound cards, graphics cards and corresponding drivers can be installed on a computer, users can use the open CNC kernel on the WINDOWSNT platform to develop required functions to form various types of CNC systems.


In addition, there are many optional functions in addition to the basic functions of the CNC system. The user can select some additional functions to be included in the attachment of the order contract according to their own workpiece processing requirements, measurement requirements, and programming requirements, especially the real-time transmission DNC function, etc. .
