The upstream of the CNC machine tool industry chain is mainly divided into four parts: CNC technology, CNC machine tool main parts, electrical components and CNC systems; the midstream is CNC machine tools, mainly including metal cutting machines, special processing machine tools and metal forming machine tools; the downstream is the application field of CNC machine tools, used primarily in automobile manufacturing, engineering machinery, rail transportation, shipbuilding, aerospace, consumer electronics, petrochemicals, military industry, etc.
The relevant introductions of each part of the upstream are as follows:
- CNC technology: It is one of the core technologies of CNC machine tools, including CNC programming, interpolation algorithms, motion control, etc.
- Main parts:
- Bearings: Support mechanical rotating bodies, reduce friction coefficients, and ensure rotation accuracy.
- Castings: Metal forming objects obtained by various casting methods, including machine tool beds, bases, workbenches, etc.
- Sensors: Devices or devices that can sense the specified measured value and convert it into usable signals according to certain rules.
- Other key components: such as lead screws, guide rails, tools, etc.
- Electrical components:
- Transformer: A device that uses the principle of electromagnetic induction to change AC voltage.
- Servo system: A feedback control system used to accurately follow or reproduce a process, mainly composed of three parts: servo motor, servo drive, and encoder.
- Servo motor: An engine that controls the operation of mechanical components in a servo system, and is an auxiliary motor indirect speed change device.
- CNC system: The “brain” of CNC machine tools is a key factor in determining their performance, function, and reliability. It comprises three parts: a control, servo, and detection system.
Some downstream application areas of CNC machine tools are introduced as follows:
- Automobile manufacturing: The total production and sales of automobiles are large, and the development of this field will affect the demand for CNC machine tools.
- Engineering machinery: It is an important part of the equipment industry, including excavators, earth-moving machinery, engineering lifting machinery, industrial vehicles, etc.
- Aviation manufacturing: The aviation manufacturing industry has high requirements for the accuracy and performance of CNC machine tools.
- Petrochemical: CNC machine tools are used in the manufacturing of production equipment in the petroleum and chemical industries.
Different fields have different needs and requirements for CNC machine tools, which has also prompted the CNC machine tool industry to continue to develop and innovate to meet diverse market needs. At the same time, with the advancement of technology, each link of the CNC machine tool industry chain is also constantly upgrading and optimizing.
