With the rapid development of the CNC cutting machine market in recent years, the competition of CNC cutting machines has entered a fever. On the one hand, the cautious selection of CNC cutting control system for the manufacturer of CNC cutting machine is one of the decisive factors that determine the future development of the enterprise. On the other hand, the use of CNC cutting control system by CNC users is a decisive decision on the use of enterprise equipment. One of the decisive factors of good and bad, it is very necessary to have a deeper understanding of the development of CNC cutting control systems at home and abroad.
When it comes to general-purpose CNC systems, people in China usually think of two large foreign companies: SIEMENS , Germany , and FUNAC , Japan . They are the world's leading CNC systems in the mechanical cold processing industry, but in the thermal cutting industry, due to heat. The speciality of the cutting process, these general-purpose CNC systems are mostly replaced by more specialized cutting-only CNC systems. At present, the most representative cutting-only CNC system in the world is the EDGE series controllers produced by Hypertherm AUTOMATION and the United States. The BURNY series controllers produced by CMC , the biggest difference between these CNC systems and the above general CNC system is that their hardware platforms are based on PC ( PC-BASED ). The popular point is to install a piece of computer in our home computer. The motion control card (similar to the graphics card), and then install a set of dedicated cutting control software to form a so-called cutting CNC system.
Therefore, we can clearly see that a cutting CNC system is composed of three parts:
( 1 ) One computer (including display and keyboard)
( 2 ) Motion control card (usually plugged into the computer bus such as the PCI bus, which completes the control of the servo and I/O )
( 3 ) A set of cutting control software (including operating systems such as WINDOWS XP , DOS, etc.)
Then understand the cutting CNC system of any one of them is to understand from the above three aspects!
Usually, the user cares about four aspects of the cutting-only CNC system that he has purchased :
( 1 ) Reliability and stability of the CNC system;
( 2 ) Control accuracy of the numerical control system;
( 3 ) The advanced nature of the CNC system;
( 4 ) The convenience of maintenance of the CNC system and the price of maintenance;
For any CNC system produced, the reliability and stability of the system are the most critical indicators. How can the user basically judge the reliability and stability of the CNC system? It is very clear that through our introduction: only the system is composed. All three parts are reliable and stable, and the whole system can be reliable and stable. Among them, the computer is the brain of the whole system. At present, most domestic systems use industrial-grade computers, but there are many manufacturers of industrial-grade computers in China. The quality of products is also very uneven. Users should choose products from well-known brand manufacturers. Motion control card and cutting control software are two other very important links of system reliability and stability. For cutting CNC systems developed at home and abroad, most of them are currently taking two paths:
(Article 1) Develop a motion control card by yourself;
(Article 2) Select general-purpose products developed by professional sports card companies in the market;
Through the above introduction. We can clearly understand that the domestic cutting CNC system is no different from the imported brand CNC system. There are no differences in the system hardware platform (even some systems are higher than them), mainly in software functions and There is still a gap in stability. The main reason for the Chinese people's distrust of their domestic systems is that some domestic systems are doing too badly, and some cutting machine manufacturers have abused these systems in order to fight the price without considering the responsibility to users, which has brought many negative effects. To solve these problems, on the one hand, the cutting machine manufacturers need to use more good systems. On the other hand, they hope that users can understand more about the CNC system. Of course, we have to admit the gap between the current system and foreign systems, and hope that the Chinese people will have more support. National brand!
Wire saw is an advanced engineering tool used in the renovation and reinforcement of construction factories. It is a special cutting tool, suitable for cutting hard materials such as reinforced concrete, rock, ceramics, brick walls, etc. The specifications of the wire saw are mainly controlled by beading. , The formula of different stones is different. The production of beads should be customized according to the actual situation of the stone to maximize the efficiency. With the continuous research and development and technology accumulation of various production units in my country, the formulation process and manufacturing of domestic diamonds have reached the international leading level.
