Description
Technical Field
The utility model relates to a cutter technical field, concretely relates to cutting process cutter.
Background
The micro-lubrication technology (MQL) is a cutting cooling lubrication method in which a compressed gas and a trace amount of lubricating fluid are mixed and vaporized, and then the mixture is injected into a machining area to effectively lubricate a machining part between a tool and a workpiece. MQL can greatly reduce the friction between 'cutter-workpiece' and 'cutter-chip', and plays roles in inhibiting temperature rise, reducing cutter abrasion, preventing adhesion and improving the processing quality of workpieces. The MQL uses few lubricating liquid, but has very obvious effect, thereby not only improving the work efficiency, but also not polluting the environment. And as long as the MQL technology is used properly, the machined cutter, workpiece and chips are dry, the post-treatment is avoided, the clean chips can be recycled after being compressed, and the environment is not polluted completely, so the technology is also called as quasi-dry cutting.
In recent years, people are increasingly conscious of environmental protection, and a clean and pollution-free green production mode is advocated in the production process. The traditional cutting lubrication mode in the machining field mainly comprises lubricating oil, emulsion, pure water and the like; however, the lubricating oil is a 'large water flood irrigation' type cooling and lubricating mode, the utilization rate of the lubricating oil is low, and the pollution is serious. Wherein the cuttings carrying a large amount of lubricant are the main output of pollution, and the cost for disposing the cuttings becomes a significant expenditure in the production cost of enterprises. In view of the above problems, the MQL cooling and lubricating system of the "drip irrigation" type has been attracting attention. Compared with the traditional cooling and lubricating mode, the using amount of the MQL lubricant is far lower than that of the former lubricant, and the utilization rate of the lubricant is also far higher than that of the former lubricant.
However, the conventional MQL has many problems in practical use, including: firstly, the application in high-temperature cutting is difficult, and the externally-sprayed atomized oil is easy to volatilize prematurely, so that almost no oil mist can enter a cutting area, and further MQL (medium-to-high temperature) fails. Secondly, the range of oil mist injection is large, but only a small part of oil mist really reaching the cutting area has limited lubricating effect on the chip area. Thirdly, in the actual machining process (such as turning), airflow is easy to spray on the surface of the chip, and the contact pressure and the contact length of the chip and the rake face are increased. And fourthly, the noise problem is also prominent in the actual processing process. Therefore, the existing minimal quantity lubrication technology (MQL) is in need of improvement.
