**1. Overview**
During the grinding process, high temperatures are generated in the grinding zone, which can lead to excessive wear of the grinding wheel, damage to the workpiece surface, and difficulty in maintaining machining accuracy. To address these issues, it is essential to introduce grinding fluid into the contact area to reduce temperature, provide lubrication, and prevent rust.
When a grinding tool interacts with a metal surface, significant heat is produced due to friction. In high-speed grinding, the contact area often experiences extreme pressure conditions, making it crucial for the grinding fluid to possess several key properties: excellent lubricity and anti-wear performance, effective cooling and cleaning capabilities, strong corrosion and rust resistance, as well as low foaming and antibacterial characteristics.
Grinding fluid plays a vital role in ensuring smooth and efficient grinding operations. Proper use of the fluid improves process stability, enhances workpiece quality, and extends the life of both the grinding wheel and the machine. Compared to other machining processes, grinding involves a large contact area between the wheel and the workpiece, leading to high friction and heat generation. This makes it challenging to supply coolant effectively, increasing the risk of thermal damage to the workpiece and accelerating wheel wear.
It is commonly believed that grinding fluids serve multiple functions such as lubrication, cooling, cleaning, and rust prevention. The performance of a grinding fluid can be categorized into three main aspects: processing characteristics, its own functional properties, and environmental adaptability. Processing characteristics refer to the fluid’s ability to cool, lubricate, clean, and maintain the integrity of the workpiece. Its functional properties relate to the physical and chemical behavior of the fluid, while environmental adaptability considers factors like odor, toxicity, and the impact on BOD and COD levels.
Grinding is typically the final stage in bearing manufacturing, directly affecting the accuracy, performance, and lifespan of the product. Using coolant during this process helps prevent workpiece burning, improves surface finish and dimensional accuracy, and enhances the anti-rust properties of both the workpiece and the machine tool. It also contributes to extending the life of cutting tools and machinery.
However, if coolant is supplied separately, controlling its concentration, pH level, and microbial content becomes difficult. The liquid supply systems used are often rudimentary, leading to rapid contamination by metal shavings and grinding dust. Over time, the coolant may degrade, causing equipment damage and compromising part quality. Frequent replacement of coolant increases labor costs, reduces production efficiency, and leads to environmental pollution when waste fluids are improperly disposed of. Additionally, coolant leaks or evaporation in the workshop can negatively affect the working environment and workers’ health.
**2. Collection, Supply, and Filtration System for Large and Medium-Sized Machining Plants**
In large and medium-sized mechanical processing plants, it is advisable to implement a centralized collection system for supplying cutting fluids to multiple machines. This approach allows for the use of a single type of fluid across different grinding machines, reducing complexity and improving efficiency. A combined transport system can collect wet chips and abrasive debris, minimizing manual disposal and enhancing workplace conditions.
The collection system enables better protection of the grinding fluid. By storing the fluid in a large tank, the factory can periodically test its quality, adjust the concentration as needed, and extend the service life of the fluid. This method reduces the number of sampling points and allows for more accurate monitoring, ensuring consistent performance throughout the process. Compared to separate fluid supply systems, this centralized approach offers greater cost-effectiveness and environmental benefits.
One of the most significant advantages of the collection system is its ability to remove oil, metal particles, and bacteria from the fluid through centrifugation. These contaminants tend to accumulate at the interface between floating oil and metal particles, making them easier to eliminate. Regular testing and analysis help determine when additives should be introduced or when the stock solution needs to be replenished. This ensures the fluid remains effective and extends its usable life, significantly reducing the amount of waste generated.
