Question 2: What are the systems of CNC machine tools? Germany's Siemens and Heidenhain, Spain's Fagor, Japan's Fanuc and Mitsubishi, more domestic but all low-end such as wide number, Beijing Kain Emperor, Shanghai opened, Wuhan Huazhong and Huaxing, Chengdu Guangtai, Shenzhen Shanshing, Aerospace Century Star, and so on, in addition to a number of well-known machine tool manufacturers have their own company-specific systems such as the United States, Haas and Hercules, Japan, but more, like Mazdaq, Makino, Okuma, Brother and so on!
Question 3: What are the types of CNC machine tool systems (1) traditional specialized CNC systems
This type of CNC system hardware developed by the CNC system manufacturers themselves, with a strong specialization, after a long period of time, the quality and performance is stable and reliable, and currently occupies most of the market in the manufacturing industry. However, due to its use of a completely closed architecture, there are often the following shortcomings:
a. The user's application, maintenance, and operator training is completely dependent on the CNC system manufacturer, the system maintenance costs are high;
b. The expansion of the system functions and updates are completely dependent on the company's technical level, the cycle is longer;
c. A large number of commercially available cheap hardware and software in the specialized CNC control. c. A large number of commercially available cheap general-purpose hardware and software can not be used in the specialized CNC system, the function is relatively single.
Therefore, with the continuous development of open architecture CNC systems, the market of this traditional specialized CNC system is being challenged, and the market share has been gradually reduced.
(2) PC embedded in the NC structure of the open CNC system
Such as FANUC16i/18i, Simens840D, NumIO60 and other CNC systems. This type of CNC system compared with the traditional specialized CNC system, the structure has some openness, very powerful, but the system hardware and software structure is very complex, the system price is very expensive, general small and medium-sized CNC machine tool manufacturers do not have the economic ability to buy.
(3) NC embedded in the PC structure of the open CNC system
The hardware part of this CNC system consists of an open architecture of the motion control card and PC organizations. Motion control card is usually used as a high-speed DSP CPU, has a strong motion control and PLC control capabilities. Such as Japan's MAZAK company with Mitsubishi Electric's MELDASMAGIC 64 constructed MAZATROL 640 CNC. this CNC system's open performance is relatively good, and to improve the function is also relatively convenient, the system's control functions are mainly realized by the motion control card, machine tool hardware changes, only need to modify the corresponding part of the control software, and the system cost-effective and relatively high, can meet most of the CNC system. Comparatively high, to meet the needs of most manufacturers of CNC machine tools.
(4) All software-type open CNC system
This is one of the latest open architecture of the CNC system, all the CNC functions (including interpolation, position control, etc.) are all realized by the computer software. Compared with the previous types of CNC systems, all-software open CNC system has the highest cost-effective, and therefore the most vital.
Question 4: What operating systems are available for CNC lathes? I know of CNC operating system FANUC CNC system; SIEMENS CNC system; Huazhong CNC system; Century Star CNC system; Mitsubishi CNC system and so on.
FANUC CNC system is more stable, while SIEMENS CNC system is more friendly and easy to get started.
Question 5: What is a CNC machine tool? CNC machine tools is short for digital control machine tools, is a program control system equipped with automated machine tools. The control system is able to logically process the program with a control code or other symbolic instructions specified, and decode it, so that the machine tool action and processing parts.
The operation and monitoring of CNC machine tools are all completed in this CNC unit, which is the brain of the CNC machine tool. Compared with ordinary machine tools, CNC machine tools have the following characteristics:
● High machining accuracy, stable machining quality;
● Multi-coordinate linkage can be carried out, and can be processed in the shape of complex parts;
● Processing of parts change, generally only need to change the CNC program, which saves the production of time to prepare;
● The machine tool itself has high precision, rigidity, can choose the amount of favorable machining, and can be used to save the production of time;
● High precision and rigidity, can choose the amount of favorable machining. Can choose the amount of favorable processing, high productivity (generally 3 to 5 times the ordinary machine tools);
● high degree of automation of the machine tool, can reduce labor intensity;
● the quality of the operator requires a higher quality, the technical requirements of the maintenance staff is higher.
CNC machine tools are generally composed of the following parts:
● host, he is the theme of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical components. He is used to complete a variety of mechanical components of cutting processing.
