Will the machining industry use compressed gas?

Compressed gas is used in the machining industry, and its application runs through many key production links, which plays an important role in improving efficiency, ensuring accuracy and realizing automatic control.. The following is a systematic description of application scenarios, equipment sources, and advantages:

core Application Scenario of 1. Compressed Gas in Machining

1. power Transmission and Tool Drive
   • pneumatic tools: Compressed gas is converted into mechanical energy through pneumatic motors, cylinders and other devices to drive pneumatic picks, drilling rigs, grinders and other tools to realize drilling, cutting, and grinding operations.
   • Automation equipment in CNC machine tools, machining centers and other equipment, compressed gas is used to drive the spindle, tool magazine, fixture and other components to achieve efficient and accurate processing.
2. Cleaning and Dust Removal
   • part surface cleaning: The use of compressed gas high-pressure airflow, quickly remove parts of the surface of the chip, oil and dust, to ensure processing accuracy and product quality.
   • Equipment maintenance regularly use compressed gas to purge the guide rail, screw and other parts of the machine tool to prevent the accumulation of impurities from affecting the performance of the equipment.
3. Fastening and fixing
   • pneumatic wrench: Through the compressed gas to drive the wrench head to rotate, the rapid fastening and disassembly of bolts, nuts and other connectors can be realized, and the assembly efficiency can be improved.
   • vacuum sucker in the automatic production line, the compressed gas is used to control the adsorption and release of the vacuum suction cup to realize the accurate grasping and placement of the workpiece.
4. automatic control
   • pneumatic control system: Compressed gas drives pneumatic valves, cylinders and other components to realize automatic control of the production line, such as workpiece conveying, positioning, clamping, etc.
   • Pressure testing and inspection: In the product quality inspection link, by filling compressed gas into the product, observing the pressure change or detecting the gas leakage, judging the sealing and pressure resistance of the product.
5. auxiliary process
   • cooling machined parts: In the process of high-speed cutting or grinding, compressed gas is used to blow the processing area to reduce the temperature of the workpiece and prevent thermal deformation.
   • Blow-drying and dehumidification: After cleaning, the surface moisture of the workpiece needs to be dried with compressed gas to prevent corrosion; in a humid environment, compressed gas can also be used for dehumidification to keep the equipment dry.

Sources and equipment of 2. compressed gas

1. air compressor system
   • core Equipment: The air compressor compresses the air in the atmosphere to a high pressure state and stores it in the air storage tank for use on the production site.
   • system composition: Including air compressor, air storage tank, dryer, filter, pipeline and control components, etc., to ensure the stable supply and cleanliness of compressed gas.
2. Special gas compressor
   • nitrogen compressor in processing occasions requiring inert gas protection, such as welding, heat treatment, etc., a nitrogen compressor is used to provide pure nitrogen.
   • Other gas compressors according to process requirements, special gas compressors such as oxygen and argon can also be used.

3. the advantages of using compressed gas

1. improve production efficiency
   • quick response: The compressed gas transmission system responds quickly, which can realize the rapid start and stop of tools and precise adjustment, and improve the processing efficiency.
   • automatic control: Reduce manual intervention, realize continuous and stable operation of the production line, and reduce labor intensity.
2. Guarantee processing quality
   • clean environment: Compressed gas effectively removes impurities in the processing process, reduces surface defects of the workpiece, and improves product quality.
   • Precise control: The pneumatic control system can achieve micron-level positioning accuracy to meet the needs of high-precision processing.
3. Reduce operating costs
   • energy saving compared with hydraulic transmission, pneumatic system is more energy efficient, and compressed gas can be recycled, reducing energy consumption.
   • Easy maintenance: Pneumatic components have simple structure, low failure rate and low maintenance cost.
4. Enhanced security
   • explosion-proof and fire-proof: In flammable and explosive environments, the compressed gas transmission system can avoid safety accidents caused by electrical sparks.
   • Overload protection: The pneumatic system has an automatic overload protection function to prevent equipment damage and casualties.

4. Conclusion

compressed gas has an indispensable position in the machining industry, and its application is extensive and deep into many production links. Through reasonable selection of compressed gas sources and equipment, and give full play to its advantages in power transmission, cleaning and dust removal, fastening and fixing, automatic control and auxiliary technology, the production efficiency, product quality and safety of the machine processing industry can be significantly improved.
