The area where the cutting tool is prone to wear during turning is the rake face. Therefore, a small amount of lubricating oil mist is sprayed and infiltrated into the process to greatly reduce the friction. When using lath oil mist lubrication, it is necessary to pay attention to the following contents: For the external injection system lathe, the installation of the micro lubrication system should not affect the movement of the processing and other components; the internal lubrication lubrication lathe is the lubricant sprayed into the form of suspended oil mist particles. In the cutting area, the reliable flow of suspended particles must be maintained. Therefore, the design of the machine tool should be considered to ensure the reliable transportation of the suspended particles and the sealing of the channel. The matching of the cutting tool holder and the cutting tool should ensure that the lubricating oil mist particles can reach the cutting area. .
The amount of back-feeding, feed and cutting line speed in lathe processing are the main factors affecting the processing quality and processing efficiency, in order to improve the influence of cutting fluid on the processing environment and the adverse effects on lathe maintenance. Research and application of micro-oil mist lubrication on lathes is necessary. The advantages of the micro lubrication method are:
1,
Reduce cutting and maintenance costs.
2. The machine tool does not need to consider the protection design to prevent leakage, which can improve the life of the electrical system and reduce maintenance costs.
3,
Better processing quality and higher processing efficiency.
4,
Improve the processing life of cutting tools.
The gas source pressure of the lathe oil mist lubrication system requires normal operation at 5-7 bar, and better results can be obtained when the gas source pressure is increased to 8-10 bar.
Refer to the following case:
material:
Aluminum alloy
Machine tool: lathe
Machine speed: 0-5000 rpm
Lubrication system: Previous 5% emulsion
Later, Cote II Miniature Lubricating Oil
Workpiece size; ¢24*98
In most cases, the lathe is cooled by the cutting fluid. The use of a large amount of cutting fluid greatly affects the operating environment and the health of the operator, and the processing cost of the cutting waste liquid is also high. Many problems with the lubrication and cooling of cutting fluids have led to new technologies to replace traditional lubrication cooling methods.
