What does CNC mean?

CNC (Numerical Control Machine Tool) is the abbreviation of computer numerical control, 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.

Control unit of NC machine tool

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.

Since MIT developed the first CNC machine tool in the world in 1952, CNC machine tools have been widely used in manufacturing industry, especially in automobile, aerospace and military industry, and CNC technology has developed rapidly in both hardware and software.

machining center

Machining center is a highly automated multifunctional CNC machine tool with tool magazine and automatic tool changing device. After the workpiece is clamped in the machining center once, more than two surfaces can be machined in various processes, and it has various functions of tool change or tool selection, which greatly improves the production efficiency.

Machining centers can be divided into boring, milling and turning according to their processing technology, and can be divided into three-axis, four-axis and five-axis machining centers according to the number of control axes.

Computer Numerical Control (CNC)

The corporate logo of China Network Communication Group (hereinafter referred to as "China Netcom Group") consists of two parts, which have distinct characteristics of the times and industries. The two interactive English letters "C" in logo form a virtual "N", which is not only the abbreviation of China Netcom to China Netcom Group, but also the freehand form of the Chinese word "Net", which vividly transforms the communication and interaction characteristics of the telecommunications industry into visual images. Its circular outline symbolizes the globalization trend of China Netcom's delegation in China, and the ingenious combination of blue background and green letters contains profound implications of science and technology and the future. Chinese fonts, with proper inclination angle, effectively convey the enterprising spirit of enterprises.

The logo has a unique artistic aesthetic feeling and symbolic significance, and it is a vital organic whole. It combines the original logos features of China Telecom North 10 province (autonomous region, municipality), China Network Communication (Holding) Co., Ltd. and Jitong Communication Co., Ltd., vividly outlines the inherent quality of China Netcom Group in integrating all positive factors and excellent resources, and embodies that China Netcom Group, as a super-large state-owned telecom enterprise, leads all employees to work together with Qi Xin.

Race to win the market

"Competition wins the market" is the strategic orientation of China Netcom Group to participate in the competition and cooperation in the telecom market with a brand-new attitude. Seek cooperation with major telecom operators and social stakeholders at home and abroad in competition, compete in an orderly manner in cooperation, actively promote equal participation in technical means, do a good job in interconnection, and achieve win-win results for all parties.

Integrated creativity

"Integrating creativity" is the premise and foundation of China Netcom Group's reform and development, and it is also the need of China Netcom Group's corporate culture construction at this stage. Every employee of China Netcom Group will adhere to the creed of "integration and creation", quickly form the cohesion of China Netcom, and lay a solid foundation for the sustainable and healthy development of China Netcom Group.

Integrity creates brand.

"Honesty" is the cornerstone of the socialist market economy, the foundation for China Netcom Group to build a well-known brand, and the most solemn and solemn commitment of China Netcom Group to society and users. China Netcom Group will win the real trust and longer-term cooperation from customers and partners, give full play to the brand effect, and fully embody the unity of economic and social benefits.

Service weaves the future

"Service Weaves the Future" is the concrete embodiment of China Netcom Group's economic strategy and the basic means to participate in future market competition. Providing quality service is the starting point and end result of China Netcom Group's business strategy, and customer satisfaction is the highest evaluation of China Netcom Group. China Netcom Group will show its brand-new service image to the society and win the initiative in the market competition.

"Competition and cooperation to win the market, integration to create strength, integrity to create brands, service to weave the future" interact, complement each other, have inherent and inevitable connections, and are a relatively systematic concept system. It will lead all employees of China Netcom Group to live up to the great trust of the Party and the people, unite as one, strive to achieve the mission entrusted by history, and seek praise from colleagues in the business field and all walks of life.
