1. Overview During grinding; high temperature in the grinding zone; wear of the grinding wheel; deterioration of the appearance of the part; difficulty in handling the machining accuracy of the part; therefore, it is necessary to write the grinding fluid into the grinding zone; lower the grinding temperature. Not only smooth and cool, but also scrub and rust proof.
When the grinding tool and the metal surface are ground and polished; there is a lot of conflict heat between the grinding tool and the workpiece; the partial temperature can be as high as several hundred degrees; and the touch surface between the grinding tool and the metal surface is often in an extreme pressure state during high-speed grinding. This requires the grinding fluid to have the following functions: 1. Excellent smoothness and kneading properties. Excellent scavenging and cooling, 3,. Excellent corrosion resistance and rust resistance, 4. Also have low foaming and antibacterial properties.
Grinding fluid plays an extremely important role in grinding; the correct use of grinding fluid can improve process stability, improve workpiece quality, and extend tool life. Compared with other machining processes; the primary feature of grinding is grinding wheel and The touch area of ​​the workpiece is large; the conflict between the abrasive particles and the appearance of the workpiece is high; the grinding arc is difficult to supply liquid; then the appearance of the workpiece is easily damaged by heat; the grinding wheel is subjected to the rated load and the wear is aggravated. It is usually thought that the grinding fluid has smoothness and cooling. , cleaning, rust and other effects.
Grinding fluid induction skill function quality can be divided into three categories: processing characteristics, its own quality function and environmental adaptability. Processing characteristics mainly refer to the cooling, smoothing, cleaning function of the grinding fluid in the process of processing and the integrity of the workpiece, things The impact of durability, etc., its quality function mainly refers to the physical and chemical functions of the grinding fluid. Environmental adaptability refers to the odor, toxicity, biological oxygen demand (BOD) and chemical oxygen demand (COD) of the grinding fluid. Environmental impact.
Grinding is the final process of ferrule machining, which has a direct impact on the accuracy, function and service life of the bearing products. In the process of machining, the coolant is used to avoid burns on the workpiece, improve the accuracy and roughness of the workpiece, and improve the workpiece and machine tool. Anti-rust ability, extended tool and machine tool life have very important effects.
If the coolant is supplied separately, its concentration and pH
The value and the number of colonies in the coolant are difficult to control, and the liquid supply system that is equipped with it is mostly rough. When the coolant is in the crucible season, even if the quality has not changed, many iron filings and grinding wheel ash will fill the water tank very quickly. The coolant is rancid and mutated during the application process, and the equipment is damaged. It is difficult to ensure the quality of the processed parts. The coolant is often replaced, which reduces the production power and brings heavy labor to the workers. Together, it also increases the production cost, and these replacements Coolant is usually discharged without treatment, which has a great impact on the environment. In addition, since the coolant supply system is built by the equipment, it is usually in the production workshop, and the transpiration and leakage of the coolant will also be It pollutes the environment of the production workshop and directly affects the well-being of workers.
2. Grinding fluid gathering supply and filtration system for large and medium-sized mechanical processing plants; where possible; should consider the use of the collecting cycle system to supply cutting fluids for multiple machines; however, it is necessary to use the same cutting fluid for each machine. Several grinding machines can handle the grinding debris with a combined transport system; collect the fine chips and wear debris that are wet by the cutting fluid; reduce manpower disposal; improve working conditions.
The grinding fluid collection system allows the factory to better protect the grinding fluid. The grinding fluid is collected in a large pool; it is periodically sampled; the raw liquid or water is compensated according to the results of the inspection; and the concentration of the grinding fluid is easy to handle; Ability to reduce the number of sample views; then perform more intent viewing; ensure the quality of the grinding fluid during the application period. Compare with many separate multi-grinding fluid supply systems that are set separately; cut due to the protection of the grinding fluid; Also relatively falling.
The most important advantage of the collection system is that it can be removed by centrifugation to remove the oil and metal particles from the grinding fluid; together with half of the bacteria in the grinding fluid (because the bacteria are very simple in the grinding fluid) The interface between the floating oil and the metal particles grows.) Remove the dirt in succession; check the quality regularly and check the results according to these; plan to use the additive or participate in the stock solution; this is to make the gathering system very useful to extend the cutting fluid The important factor in the application of life. This also cuts the disposal of water-soluble grinding fluid waste.
