At present, there are cutting oil casting lubrication processing, dry cutting processing, micro-lubrication processing, low-temperature trace lubrication process and other forms of metal cutting. The traditional cutting oil lubrication causes great pollution to the operating environment and consumes large amounts of energy. Dry cutting has relatively high requirements for the performance of machine tools and cutting tools, and the cost of cutting tools is high.
Minimal lubrication avoids the environmental problems caused by large amounts of cutting oils and the subsequent cleaning of workpieces. At the same time, it can also obtain better machining accuracy and surface quality. It can not only ensure high processing efficiency, but also increase the service life of cutting tools and reduce Energy consumption, only need to apply a small amount of oil 10-50ml per hour to provide lubrication for cutting tools.
Relative to the cutting oil lubrication lubrication process, the high temperature of the micro-lubrication process. High-speed machining under a small amount of lubrication ensures the long life of the cutting tool, mainly because the ultra-fine oil mist particles facilitate penetration into the cutting area to form an oil film and reduce friction between the cutting tool-workpiece and the cutting tool-chip. , It plays a role in suppressing temperature rise, reducing wear, preventing adhesion, and improving the quality of the workpiece surface and the life of cutting tools. The oil mist type micro-lubrication machining cutting tool is always maintained in a stable cutting temperature range, and no repeated thermal shock effect when the cutting oil is used for watering, resulting in micro cracks of the cutting tool tool and further expansion, direct chipping, coating peeling Such phenomena affect the tool life.
For some special metal materials, such as titanium alloys, high hardness materials and high temperature alloys, the use of low temperature and trace lubrication has better results. At present, low-temperature gases mainly include nitrogen, carbon dioxide, and low-temperature cold air. When low-temperature gases and a very small amount of lubricating oil are injected into the processing area, both the lubrication problem and the cooling problem of the cutting process are solved, and there is a very good market prospect.
The advantages of trace lubrication are as follows:
(1) The oil mist can penetrate into the friction point, which can play a good role in lubrication and inhibit temperature rise;
(2) Compressed air can take away the heat of cutting, and a large amount of cutting heat is carried away with the chips.
(3) low oil consumption, cutting friction points always maintain a proper amount of reliable lubrication;
(4) The product has a small volume and consumes low gas.
easy to use;
(5) Reduce the maintenance costs and operating costs of the machine tool;
As the impact of cutting fluids on the environment has become increasingly significant, so the requirements for energy saving and environmental protection are increasing day by day. Choosing the right lubrication method is especially important. Minimal lubrication can help companies reduce operating costs.
