large number of research results have proven that in the cutting applications of materials such as titanium alloys, stainless steel, high-temperature alloys and hardened steel, compared with the use of dry cutting and wet cutting, minimum quantity lubrication can improve cutting performance. It has good effect and the reasonable use of minimum quantity lubrication can effectively improve the durability of the tool and improve the quality of the workpiece and machined surface.
Since conventional
minimum quantity lubrication technology uses high-speed cutting of difficult-to-machine materials, the temperature in the cutting zone is too high, which will cause the lubricating film on the tool surface to lose its lubrication effect. Effective cooling methods can further improve the effect of minimum quantity lubrication. . If the temperature of the existing compressed air can be significantly reduced, on the one hand, it can increase the intensity of heat transfer in the cutting area and improve the heat transfer effect. On the other hand, the improvement in heat transfer effect can maintain the lubricating film formed by lubricating oil droplets on the tool surface. Original lubrication ability, thereby improving the durability of the tool. If micro-lubrication is combined with nitrogen, the cutting performance will be greatly improved. This is mainly because nitrogen can play a good role in blocking oxygen.
High-speed dry cutting fundamentally solves the disadvantages caused by cutting fluid. It is not only beneficial to the health of workers and the protection of the environment, but also can reduce processing costs. It is undoubtedly a promising green processing technology. However, the application fields are subject to certain restrictions.
Minimum quantity lubrication technology is an effective green manufacturing technology, with outstanding features in lubrication, chip removal, etc., low temperature
Minimum quantity lubrication technology, as a new cooling and lubrication technology that is convenient for application at machining sites, is widely used in It has excellent performance in high-speed processing of difficult-to-machine materials such as titanium alloys, high-temperature alloys, and high-hardness materials. It can further improve the processing rate and processing quality of difficult-to-machine materials based on current process equipment.
