CNC milling is a high precision machining method, which requires the use of various tools and materials to ensure the quality and accuracy of the working surface. Coolant and lubricant are two very important materials in CNC milling process, which can make the machining more smooth and accurate.
CNC milling machining is a widely used manufacturing process that involves the use of computer-controlled machines to produce complex parts and components. This process involves the removal of material from a workpiece using a rotating cutting tool. During this process, the cutting tool generates a lot of heat, which can cause damage to the cutting tool and the workpiece.
In actual use, we need to choose different types of coolant and lubricant according to different machining materials and machining conditions. For example, for iron materials, we can use water-soluble cutting fluid as coolant and lubricant; And for copper, aluminum and other stainless steel materials, we can use pure liquid lubricant, in order to ensure the quality and accuracy of the processed surface.
To prevent this, coolants and lubricants are used in CNC milling machining. Coolants and lubricants play a crucial role in the manufacturing process, as they help to reduce heat, friction, and wear on the cutting tool and workpiece.
Coolants are used to cool down the cutting tool and workpiece during the machining process. They help to prevent the cutting tool from overheating and breaking, which can cause damage to the workpiece. Coolants are also used to flush away chips and debris from the cutting area, which helps to improve the machining accuracy and surface finish of the workpiece.
Lubricants, on the other hand, are used to reduce friction between the cutting tool and workpiece. They help to prevent the cutting tool from wearing out too quickly, which can cause damage to the workpiece. Lubricants also help to improve the surface finish of the workpiece by reducing the amount of heat generated during the machining process.
In addition to cooling and lubrication, coolants and lubricants also play a role in preventing corrosion and rust on the workpiece. This is particularly important for parts and components that are made from materials that are prone to corrosion and rust.
When selecting a coolant or lubricant, it is important to choose one that is compatible with the materials being machined and the cutting tool being used. Different coolants and lubricants have different properties and are designed for specific applications. For example, water-soluble coolants are ideal for machining non-ferrous metals, while oil-based coolants are better suited for machining ferrous metals.
Using the right coolant or lubricant can also help to extend the life of the cutting tool and improve the efficiency of the machining process. Coolants and lubricants can help to reduce tool wear, which can lead to longer tool life and fewer tool changes. This can result in reduced downtime and increased productivity.
The role of lubricant in CNC milling
Lubricant is a material used to reduce the friction between two contact surfaces. Its main function is to maintain the sliding action between the tool and the workpiece surface, reduce energy loss, and extend the service life of the tool and the workpiece. In CNC machining process, the lubricant can reduce the stress and thermal deformation of the workpiece surface, so as to improve the machining accuracy and surface quality.
To make the best use of the lubricant, it is necessary to choose the appropriate lubricant type and use method. For example, under low speed and high load conditions, high viscosity lubricants are required to ensure sliding properties and lubrication between the tool and the workpiece surface. Under high speed and light load conditions, low viscosity lubricants or jet lubricants should be used to reduce energy loss and reduce processing temperature.
In conclusion, the use of coolants and lubricants is essential for the online CNC machining process. They help to reduce heat, friction, and wear on the cutting tool and workpiece, improve machining accuracy and surface finish, and prevent corrosion and rust on the workpiece. By selecting the right coolant or lubricant for your specific application, you can improve the efficiency and quality of your CNC milling machining process, and ultimately, increase your productivity.
