The Application of Lubrication and Cooling in High-Speed Numerical Control Processing
High-speed numerical control processing is a kind of high precision machining technology, which requires extremely high requirements on temperature during the machining process. In order to ensure the machining accuracy of parts at high speed, lubrication and cooling are essential, which can not only reduce the cutting force and the cutting temperature during the cutting process, but also guarantee the tool life and machining quality. This paper mainly introduces the application and preparation of lubrication and cooling in high-speed numerical control processing.
Lubricants and coolants are an important aspect of high-speed numerical control machining, as they are integral components of the system’s performance. The use of proper lubrication and cooling for each operation is the key to obtaining desired results. In high-speed numerical control machining, the dry cutting force, chip breakage force and friction coefficient of the cutting edge can be reduced by cooling and lubrication, and the cutting force, temperature rise and tool wear can be prevented.
In order to prepare a proper lubricant and cooling system for high-speed numerical control machining, it is necessary to consider the properties of the cutting fluid. Liquid cutting fluids are often to used in machining operations like drilling and milling. In addition to providing lubrication, coolants also help to reduce friction, reduce heat, remove chips, protect the tools and surfaces, improve surface finish and flush away residual particles. Cutting fluid also helps to reduce vibration and noise, which is important in high-speed numerical control machining.
The selection of the cutting fluid is determined by the materials processed and the type of work to be performed. Generally speaking, water is used as a cutting fluid for some light cutting operations or general machining, whereas oil is used for more intensive cutting operations. The coolant for high speed numerical control machining should have properties such as good lubricity, cooling utility and cleaning ability.
The use and operation of lubricants and coolants in high-speed numerical control machining are just as important as the selection of the cutting fluid. To ensure proper function, a cutting fluid must be applied in the prescribed manner and under controlled conditions. Generally, cutting fluid is supplied by a pump that sprays the fluid onto the cutting tool. This reduces grinding noise and vibration, and cools the cutting area.
The use of lubrication and cooling in high-speed numerical control machining is very important. Proper selection and application of the cutting fluid can help to shorten the machining time and improve machining quality. In addition, proper operation and control can not only reduce the cutting force and temperature during the cutting process, but also control the shape and dimensional accuracy of parts, improve surface finish and extend tool life.
