In most cases, lathes use cutting fluid lubrication and cooling. The use of a large amount of cutting fluid has a great impact on the operating environment and the health of the operators. At the same time, the processing cost of cutting waste fluid is also very high. Due to the many problems existing in cutting fluid lubrication and cooling, new technologies have emerged to replace the traditional lubrication and cooling methods. In the turning process, the area where the cutting tool is prone to wear is the rake face. Therefore, spraying and penetrating a small amount of lubricating oil mist into this during the machining process will greatly reduce the friction. When applying trace oil mist lubrication to the lathe, the following should be paid attention to: For the external injection system lathe, the installation of the trace lubrication system should not affect the processing and the movement of other parts; the internal cooling lubrication lathe is the lubricant sprayed in the form of suspended oil mist particles. The cutting area must maintain a reliable flow of suspended particles. Therefore, the design of the machine tool should consider ensuring the transportation of suspended particles and the reliable sealing of the passage. The selection of the cutting tool jacket must match the cutting tool and ensure that the lubricating oil mist particles can reach the cutting area. The main influencing factors of machining quality and machining efficiency include the amount of back-cutting, feed rate, cutting linear speed, etc., in order to improve the impact of the cutting fluid on the machining environment and the adverse impact on the maintenance of the lathe. It is necessary for the research and application of micro-oil mist lubrication of lathes. The advantages of the micro-lubrication method are:
1. Reduce cutting costs and maintenance costs.
2. The machine tool does not need to consider the protection design to prevent leakage, which can increase the life of the electrical system and reduce the maintenance cost.
3. Better processing quality and higher processing efficiency can be obtained.
4. It can increase the machining life of cutting tools. <The air source pressure of the micro-oil mist lubrication system of the lathe is required to operate normally at 5-7bar, and better results can be obtained when the air source pressure is increased to 8-10bar.
