In machine tools, compressed air is widely used in many aspects, the following are specific application scenarios:
1. Drive pneumatic tools and machine equipment
- compressed air is the main power source of pneumatic tools and machinery. For example, in a mechanical processing plant, commonly used pneumatic tools and equipment such as punching machines, drilling machines, and fitter machines require compressed air to drive.
- In CNC machine tools, compressed air is also used in the processes of opening and closing of the tool magazine door, blowing and cooling, clamping of the worktable, and loading and unloading. In the field of precision machine tools, the use of compressed air machine is more extensive. In order to improve the service life of equipment, reduce manual maintenance and ensure the accuracy of machine tools, machine tool manufacturers are using compressed air machines.
2. Cleaning and cooling
- compressed air can be used to clean parts and equipment, such as blowing away metal chips, dust and other dirt, to ensure the cleanliness of the processing process. This cleaning method is more thorough and does not need to touch the surface of the part, but it is necessary to note that parts that are sensitive to the surface or have small gaps may not be suitable.
- During machining, compressed air is also used to blow away chips and contaminants from tools and workpieces, as well as to cool tools and equipment to prevent overheating.
3. Control system operation
- many pistons and valves in mechanical equipment require compressed air to control and operate. For example, conveyor belts, clamping devices and automatic positioning devices of automatic processing lines all require compressed air control. The operation of the control system is realized by controlling the pressure and flow of compressed air.
4. Special processing process
- in some special processes, such as sandblasting equipment, compressed air is also the main power source. The sand blasting equipment uses compressed air to flow at high speed in the spray gun to form a negative pressure to generate an ejection effect. The abrasive is sucked into the spray gun through the sand pipe, and then the compressed air flow is sprayed at high speed from the nozzle to the surface of the workpiece to achieve the purpose of sand blasting.
5. Maintenance and maintenance
- compressed air is also used for the maintenance and maintenance of the machine tool, such as purging the dust and debris inside the machine tool to keep the machine tool clean and running normally.
In summary, compressed air plays a vital role in processing machine tools. It not only drives pneumatic tools and machinery equipment, cleans parts and equipment, controls the operation of the system, but also participates in special processing and maintenance work. Therefore, ensuring the supply and quality of compressed air is essential for the normal operation and processing quality of the processing machine.
