**Abstract**
In the aerospace industry, achieving high-quality, high-efficiency, and low-cost production requires meticulous attention to every detail. One of the most critical factors in this process is the selection of cutting fluid, which directly affects the surface quality and machining accuracy of the workpiece. The choice of cutting fluid depends on various factors, including the material being machined, the type of machining process, and the tool material used. As aerospace components increasingly use thin-walled structures and difficult-to-machine materials, manufacturing precision faces greater challenges. Therefore, the cooling, lubrication, cleaning, and rust-prevention performance of cutting fluids must be tailored to specific processing conditions, such as the material type, tool material, and machining requirements.
Currently, common cutting tools used in aerospace manufacturing include carbon tool steel, alloy tool steel, high-speed steel, carbide, ceramics, and diamond. Each of these tools is suited for different materials and machining environments, and the corresponding cutting fluids are also selected accordingly. For example, in the machining of aluminum alloys, emulsions are widely used. These emulsions are typically diluted with water and a concentrate, and their concentration, pressure, and flow rate significantly impact the final part quality. In open-cutting operations like turning and milling, lower concentrations (3%–5%) are sufficient due to smooth chip removal. However, in closed environments like drilling or tapping, higher concentrations (5%–8% or even 8%–10%) are needed to ensure proper lubrication and chip evacuation.
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 workpiece surface. During hole machining, poor chip removal can lead to excessive heat buildup, causing tool wear and damage to the workpiece surface. To address this, not only should the tool geometry be optimized for chip separation and removal, but the cutting fluid must also provide excellent cooling, lubrication, and cleaning properties. Products like Basso’s Blasicut BC20 and Castrol Alusol B are commonly used for their versatility and effectiveness in various machining applications.
In titanium alloy machining, which is common in aerospace, special cutting fluids are required to meet the demanding conditions. Basso Lubrication’s Vasco 5000 is an innovative water-based cutting fluid that improves machining efficiency and tool life. Combined with technologies like Sandvik Coromant’s HPC (High Pressure Cooling) and Capto systems, it provides precise cooling and chip evacuation. Flowserve’s RENODRILL 2190 is another solution for deep-hole drilling and other challenging processes involving hard materials.
For wire cutting of brittle materials like silicon wafers, especially in solar panel manufacturing, the demands on cutting fluids have increased. The fluids must be non-polluting, low-viscosity, and free of impurities to avoid damaging the wafer. Additionally, they should be easy to clean and leave no residue. However, current cutting fluids are often generic, leading to inefficiencies and problems in the cutting process. Research into specialized fluids for different cutting methods is urgently needed, especially for materials like germanium and gallium arsenide, where oil-based fluids are still commonly used.
With the growing use of cutting fluids, environmental concerns and rising costs have become significant issues. To address this, green processing technologies like Minimum Quantity Lubrication (MQL) are gaining popularity. MQL uses a small amount of environmentally friendly cutting fluid mixed with compressed air to deliver precise lubrication and cooling. This method reduces waste, lowers costs, and minimizes environmental impact. The cutting fluid used in MQL must still offer cooling, lubrication, cleaning, and anti-rust properties, while being non-toxic, biodegradable, and stable over time.
As modern manufacturing evolves, flexible and agile production systems are becoming more prevalent. This shift brings new challenges in selecting appropriate cutting fluids for multi-tasking machines. These machines perform a wide range of operations—such as milling, drilling, and tapping—requiring cutting fluids with both excellent cooling/lubrication and extreme pressure resistance. For instance, when machining aluminum parts with embedded steel components, the fluid must also offer some rust protection. Green manufacturing trends are driving the adoption of MQL technology, which aligns with the goals of sustainability and resource efficiency in the 21st century.
Prefabricated House
What is the quality of prefabricated house? Can it be used for a long time?
Many areas are now using prefabricated house. In fact, this type of house is to prepare the internal structure of the house in advance, and then complete the assembly of the house. In this way, the construction type, area, interior decoration, etc. of the house can be completed at one time, the construction efficiency is faster, and the cost is relatively favorable. But how is the quality of such housing? Can it be used for a long time?
Is the quality of prefab houses guaranteed?
Most people do not have a deep understanding of prefabricated houses, and always think that the quality of such houses is average, and problems may even occur in a short time. The Prefabricated K House and Folding Container House produced by Henan Jinming are checked at all levels from the procurement of raw materials to the later construction process to ensure that the construction site is constructed by professional workers, and the regular construction party will also provide us with long-term after-sales service. So you don't have to worry about its quality, it can be guaranteed for 30 years of long-term use.
How long does it take to build a prefab house?
The reason why such houses are being used in many areas is mainly because their production cycle is relatively short. Because prefabricated houses are all produced by workers on the assembly line, the production efficiency is high, and the quality is guaranteed, so the production cycle is relatively short. Moreover, formal businesses will conduct strict quality inspections on them, so even if they are mass-produced, they can guarantee to provide high-quality residential houses in a short period of time.
Is Prefab Home Construction Fast?
After the prefabricated house is finished, it also needs to be constructed on site, because the main body has been fabricated, and its construction has standardized requirements. Compared with traditional house construction, its construction efficiency is high, and the construction can be completed in a short time. Especially for some construction sites, the construction efficiency of such houses is high, and workers can live in high-quality houses immediately.
In fact, as long as you can cooperate with regular merchants, you can also guarantee the purchase of suitable prefabricated houses. Moreover, the quality of such houses is guaranteed, the cost is favorable, and the cost-effective prefabricated houses are also very worth choosing.
