Metalworking fluids are generally divided into two main categories: pure oily cutting fluids and water-soluble cutting fluids. These fluids play a crucial role in the machining process by enhancing performance, protecting tools, and ensuring the quality of the finished product. To be effective, metalworking fluids should provide the following key functions:
1. Enhance the surface finish of the workpiece, resulting in a smoother and more refined appearance.
2. Maintain dimensional accuracy by reducing wear and improving tool stability during machining.
3. Prolong the life of cutting tools by minimizing friction and heat buildup.
4. Efficiently remove chips and clean the machined surface to prevent contamination.
5. Protect machined parts from corrosion or rust, especially in humid or aggressive environments.
6. Increase machining efficiency by reducing energy consumption and cycle times.
7. Provide continuous cooling to both the workpiece and the cutting tool, preventing overheating.
In addition to these functional requirements, metalworking fluids must possess certain essential properties:
1. Excellent boundary lubrication and extreme pressure (EP) characteristics to reduce friction and prevent tool failure.
2. The ability to prevent welding between the cutting tool and the workpiece material, which can lead to tool damage.
3. Good thermal conductivity and heat resistance to manage temperature effectively during high-speed operations.
4. Strong corrosion and rust resistance to protect both the workpiece and the machine components.
For **pure oily** cutting fluids, additional qualities are required:
1. They should remain stable over long periods without corroding metal surfaces, oxidizing, or changing color.
2. They should not produce smoke, odors, or unpleasant smells during operation.
3. They must resist emulsification and maintain clarity, avoiding sedimentation or sludge formation.
4. They should not have any negative impact on the machined parts, such as discoloration or surface degradation.
For **water-soluble** cutting fluids, specific requirements include:
1. They should remain well-emulsified even in hard water conditions (300–700 ppm), avoiding separation or layering.
2. They need to have strong antibacterial and anti-corrosion properties, with no offensive odors.
3. Excellent anti-foaming characteristics to ensure smooth operation and prevent air entrapment.
4. The ability to quickly separate from the cutting chips for easy removal and recycling.
5. They should not leave deposits on tools or cause etching, ensuring the longevity and performance of the cutting equipment.
By meeting all these criteria, metalworking fluids contribute significantly to the overall efficiency, safety, and quality of the machining process.
Prefabricated T House
What are the installation characteristics of prefabricated T house?
The practicability of the prefabricated T house is still very good. It only needs to determine the design requirements, and the construction and construction of the house can be completed immediately, and the long-term use is also guaranteed. But you still need to pay attention to the basic characteristics when installing the house.
Good fire and sound insulation
Now this kind of houses are built with sandwich panels. Commonly used are Eps Sandwich Panel, pu Sandwich Panel, Rock Wool Sandwich Panel, so it can achieve good fire prevention effect, and at the same time, it can also have good thermal insulation performance and sound insulation. effects etc. Therefore, the living comfort of such a house is guaranteed, and even if it is used for a long time, the sound insulation effect can be guaranteed without affecting daily life.
very easy to install
Because the prefabricated T-shaped houses are produced by standardized prefabrication in the factory, their overall construction and installation are also very convenient, and they can be disassembled at any time. Even if you don't continue to use the house, you can disassemble the steel plate at any time and store it in the warehouse. This can save construction time and also save a lot of labor costs.
Recyclable
All materials and components inside the house can be recycled for a long time, especially many steel plates are galvanized, even if they are used for ten or twenty years, there will be no rust and other problems, which can ensure their long-term use . The use of prefabricated T-shaped houses can effectively reduce construction waste, and can also play a good role in environmental protection.
easy to transport
The steel plates after dismantling of this kind of houses occupy a small area, are convenient to transport, and are light in weight, so construction and transportation are also very convenient. Most mobile homes are directly equipped with wheels. After the house is built, the daily transportation is very convenient, and the overall cost can also be saved.
strong security
The safety of the prefabricated T-shaped house is still very good, even if it encounters strong winds, strong earthquakes, etc., it can also guarantee its safe use. As long as the construction can be carried out according to our needs and the subsequent stable construction can be completed, the long-term use of such houses is also guaranteed.
