What are the CNC machine tool systems?

Question 1: What operating systems were installed in previous CNC lathes? Generally speaking, Guangzhou cnc (gsk) ranks first in China, followed by Beijing KND. Nanjing Huaxing, Nanjing Renhe, Beijing Aerospace and Hangzhou Jiazheng are still unknown, and their performance is not very stable.

Fanuc in Japan, Mitsubishi, Omori and Siemens in Germany are commonly used abroad.

Choosing a system depends on the functional cost performance requirements of your machine tool.

Domestic ones are similar, while foreign ones require higher accuracy and function.

Question 2: What are the systems of CNC machine tools? Germany's Siemens and Heidenham, Spain's Fage, Japan's Fanuc and Mitsubishi, there are many in China, but they are all low-end. For example, Guangzhou Digital, Beijing Kaiendi, Shanghai Open, Wuhan Huazhong and Huaxing, Chengdu Guang Tai, Shenzhen Satellite, Aerospace Century Star and other well-known machine tool manufacturers have their own dedicated systems, such as Haas and Heck in the United States, and more in Japan, such as Madzak, Mu Ye and Dawei.

Question 3: What kinds of CNC machine tool systems (1) are there?

The hardware of this CNC system is developed by the manufacturer of CNC system, which has strong specificity. After a long period of use, the quality and performance are stable and reliable, and it still occupies most of the manufacturing market. However, due to its completely closed architecture, it often has the following shortcomings:

A. The user's application, maintenance and operator training completely depend on the manufacturer of the numerical control system, and the system maintenance cost is high;

B. The expansion and update of system functions completely depends on the technical level of the company, and the cycle is relatively long;

C. A large number of cheap general-purpose hardware and software on the market can't be used in special numerical control systems, and their functions are relatively simple.

Therefore, with the continuous development of open architecture CNC system, the market of this traditional dedicated CNC system is being challenged, and its market share has been gradually decreasing.

(2) Open CNC system with 2)PC embedded in CNC structure.

Such as Fanuc 16i/ 18i, Siemens 840d, Numio 60 and other numerical control systems. Compared with the traditional special CNC system, this kind of CNC system is open in structure and powerful in function, but the hardware and software structure of the system is very complicated and the price of the system is very expensive, which is beyond the reach of ordinary small and medium-sized CNC machine tool manufacturers.

(3) Open CNC system, in which NC is embedded in PC structure.

The hardware part of the numerical control system consists of an open motion control card and a PC. Motion control card usually uses high-speed DSP as CPU, which has strong motion control and PLC control ability. For example, Mazatorl 640CNC built by Japanese MAZAK Company with mitsubishi electric's MELDASMAGIC 64. This kind of numerical control system has good openness and is convenient for function perfection. The control function of the system is mainly realized by the motion control card. When the hardware of the machine tool changes, it is only necessary to modify the corresponding control software. The system has a high cost performance and can meet the needs of most CNC machine tool manufacturers.

(4) Full-software open CNC system

This is a new type of open CNC system. All CNC functions (including interpolation and position control) are realized by computer software. Compared with the previous CNC system, the full software open CNC system has the highest cost performance, so it has the most vitality.

Question 4: What are the operating systems of CNC lathes? The CNC operating system I know is FANUC CNC system; Siemens numerical control system; Huazhong numerical control system; Century star numerical control system; Mitsubishi CNC system, etc.

FANUC CNC system is relatively stable, while Siemens CNC system is friendly and easy to use.

Question 5: What is a CNC machine tool? CNC machine tool is the abbreviation of CNC machine tool, and it is an automatic machine tool with program control system. The control system can use control codes or other symbolic instructions to logically process and decode the program, so as to make the machine tool move and process parts.

The operation and monitoring of CNC machine tools are completed in this CNC unit, which is the brain of CNC machine tools. Compared with ordinary machine tools, CNC machine tools have the following characteristics:

High machining precision and stable machining quality;

● Multi-coordinate linkage can be carried out to process parts with complex shapes;

● When the machined parts change, it is generally only necessary to change the numerical control program, which can save the production preparation time;

● The machine tool itself has high precision and rigidity, and can choose favorable processing dosage and high productivity (generally 3~5 times that of ordinary machine tools);

The machine tool has a high degree of automation, which can reduce labor intensity;

● Require higher quality of operators and higher technical requirements of maintenance personnel.

CNC machine tools generally consist of the following parts:

● Main machine is the theme of CNC machine tools, including machine body, column, spindle, feed mechanism and other mechanical parts. It is a mechanical component used to complete various cutting processes.

● CNC device is the core of CNC machine tools, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.). ) and corresponding software are used to input digital parts programs, and complete the storage, data conversion, interpolation operation and various control functions of input information.

● Driving device is the driving part of the executive mechanism of CNC machine tools, including spindle driving unit, feed unit, spindle motor and feed motor, etc. Under the control of numerical control device, he realizes the spindle and feed drive through electric or electro-hydraulic servo system. When multiple feeds are linked, positioning, straight line, plane curve and space curve can be processed.

● Auxiliary equipment refers to some supporting components necessary for the operation of CNC machine tools, such as cooling, chip removal, lubrication, lighting and monitoring. It includes hydraulic and pneumatic devices, a chip removal device, an exchange workbench, a numerical control turntable and a numerical control indexing head, as well as a cutter and a monitoring detection device.

● Programming and other auxiliary equipment can be used to program and store parts outside the machine.
