**Abstract**
For aerospace products, achieving high quality, high efficiency, and low cost requires meticulous attention to every detail. The choice of cutting fluid directly impacts the surface finish and machining accuracy of the workpiece, and it is closely related to the material being processed, the machining process, and the tool materials used. As aerospace components increasingly incorporate thin-walled structures and difficult-to-machine materials, manufacturing precision faces greater challenges. The performance requirements for cooling, lubrication, cleaning, and rust prevention of cutting fluids vary depending on the workpiece material, tool material, processing characteristics, and specific process needs. Ensuring the final product quality demands strict control over every step of the manufacturing process.
Currently, common cutting tools used in aerospace manufacturing include carbon tool steel, alloy tool steel, high-speed steel, cemented carbide, ceramics, and diamond. Each type of tool is suited for different materials and environments, requiring tailored cutting fluids that meet specific operational demands. For example, in aluminum alloy machining, emulsions are widely used. These are typically diluted from concentrates and water, serving functions such as cooling, lubrication, and chip removal. The concentration, pressure, and flow rate of the emulsion significantly affect part quality. In open-cutting operations like turning and milling, a lower concentration (3%–5%) is sufficient, while in closed environments like drilling and tapping, higher concentrations (5%–8% for drilling, 8%–10% for tapping) are needed to ensure proper chip evacuation and lubrication.
In face milling, where cutting speeds are high and chip volume is large, a high-flow cutting fluid is essential to prevent chips from scratching the surface. Hole machining presents additional challenges due to poor chip evacuation and heat buildup, which can damage the tool and degrade surface finish. Proper cutting fluid selection, along with optimal tool geometry, is critical to maintaining performance and tool life.
In the aerospace industry, titanium and its alloys are commonly used for critical structural parts, demanding advanced cutting fluids. Basso Lubrication’s Vasco 5000 is a water-based fluid designed to enhance machining efficiency and tool life. Innovations like Sandvik Coromant’s high-pressure cooling (HPC) system and Flowserve’s RENODRILL 2190 further improve performance in challenging titanium machining tasks.
Wire cutting of hard and brittle materials, especially silicon wafers, has seen rapid growth. As wafer sizes increase and thicknesses decrease, cutting fluids must be environmentally friendly, low-viscosity, and free from impurities. Current cutting fluids lack specificity, leading to inefficiencies. Research into specialized fluids for different processes, particularly for materials like germanium and gallium arsenide, is crucial for future advancements.
With growing environmental concerns, traditional cutting fluids have become problematic due to pollution and rising costs. Minimum Quantity Lubrication (MQL) technology offers a sustainable alternative by using small amounts of eco-friendly fluids mixed with compressed air, providing precise lubrication and cooling without excessive waste. MQL not only reduces environmental impact but also improves tool life and machining efficiency.
As modern manufacturing evolves, flexible and agile production methods are becoming standard. Multi-tasking machines require cutting fluids that offer excellent cooling, lubrication, and extreme pressure resistance. Additionally, some aluminum parts may contain steel inserts, necessitating anti-corrosion properties in the fluid. Green technologies like MQL are now central to the development of sustainable, efficient, and environmentally responsible aerospace manufacturing.
Industrial Steel Buildings
Industrial steel structure buildings have a wide range of uses, and the high cost performance is worth choosing!
Industrial steel structure buildings are used in various industries, and their construction is convenient, and different steel structure buildings can be designed, which can also meet the needs of daily factories. Let's introduce the specific advantages of using steel structure buildings.
Wide range of uses
The scope of application of industrial steel structure buildings is still very wide. In addition to the use of factories as Steel Structure Workshop, some daily storage centers use Steel Structure Warehouse as warehouse, as well as gymnasiums, dormitories, etc., are actually buildings that can use steel structures. And not only the ground floor can be built, as long as the design is reasonable, then high-rise and multi-storey buildings can be constructed and applied.
Simple construction
Compared with traditional building construction, the construction of the steel structure itself is very simple, and all components are prefabricated and have certain standard sizes, which can be installed directly. The construction efficiency is high, and the construction of the plant can be completed in a short time. And generally it can be directly spliced, which greatly shortens the construction time, and the construction of large-scale buildings can be completed in less than one month.
High durability
Industrial steel structure buildings can be used for a long time, not just temporary use for a month or two, and the stability of the steel structure is also guaranteed. Moreover, the daily maintenance of the building is simple, and the design and construction of the building can be completed directly through computer design. Even if it is used in bad weather, there will be no problems, and it is suitable for long-term use.
beautiful and practical
Steel structure buildings come in many different colors, and manufacturers can also provide customized processing services. The design of the building is simple and beautiful, and it can also be decorated internally. Such a building has strong flexibility in use and can meet the requirements of different projects for long-term use.
Cost discount
Industrial steel structure buildings are light in weight, and the price of steel structures is favorable, and the cost performance is still good. Because of the high construction efficiency of its buildings, labor costs are also very cost-effective. It only needs to complete the design and construction, and the building can be put into use immediately, and the overall cost performance is also good.
