What does a COMPUTER NUMERICAL CONTROL machine mean, and what does a CNC machine mean?

CNC machine tool is the abbreviation of computer numerical control machine tools, which is an automatic machine tool equipped with a program control system. The control system is able to logically process and decode the programs specified by the control code or other symbolic instructions, so that the machine tool can operate the CNC press brake and process the parts.

To put it simply, through computer operation, the production and processing components of machine tools and equipment can be controlled.

PC numerical control system. It is developed on the basis of industrial computers.

Many people don't know, as long as it is a CNC system with a hard disk, it is a PC CNC system.

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system is able to logically process and decode programs with control codes or other symbolic instructions so that the machine can move and the parts are machined.

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

High machining accuracy and stable processing quality;

It can carry out multi-coordinate linkage and process parts with complex shapes;

When the processed parts are changed, generally only need to change the CNC program, which can save production preparation time;

The machine tool itself has high precision and rigidity, and can choose a favorable processing amount, and the productivity is high (generally 3 5 times that of ordinary machine tools);

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

The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

CNC machine tools are generally composed of the following parts:

The main machine, which is the subject of CNC machine tools, includes mechanical components such as machine body, column, spindle, feed mechanism, etc. He is a mechanical component used to complete various cutting operations.

The numerical control device is the core of the CNC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and the corresponding software, which is used to input the digital part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.

The drive device is the driving component of the actuator of the CNC machine tool, including the spindle drive unit, the feed unit, the spindle motor and the feed motor. He implements the spindle and feed drive by means of an electrical or electro-hydraulic servo system under the control of a numerical control unit. When several feeds are linked, positioning, straight lines, plane curves and spatial curves can be processed.

Auxiliary devices, some necessary supporting parts of the index control machine tool, are used to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.

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

Since 1952, the Massachusetts Institute of Technology developed the world's first CNC machine tool, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries.

1.CNC machine tool is the abbreviation of computer numerical control machine tools, which is an automatic machine tool equipped with a program control system.

2.The control system can logically process the program specified in the control code or other symbolic instructions, and decode it, quietly display it with the first-class digital table code, and input the numerical control device through the Luhu information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the action of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing.

3.CNC machine tool better solves the problem of complex, precise, small batch, multi-variety parts processing, is a flexible, high-efficiency automatic machine tool, represents the development direction of modern machine tool control technology, is a typical mechatronics products.
