There are many cutting tools and materials used in CNC machining centers, and the materials used for engraving and milling are widely used, ranging from hard to various metals, marble, soft to PVC, plexiglass, two-color plates, etc. Therefore, it is very important to have a good tool for engraving and milling products of what material, what tool to use, and to process a good product.
Numerical control processing (CNC lathe processing) not only requires whether the tool is sharp, but also requires whether the model, size, material, and parameters of the tool are appropriate, which will affect the quality and efficiency of engraving and milling.
Reasonable selection of cutting tools in CNC machining and optimization of processing methods can improve processing efficiency and prolong tool life, especially in the processing of difficult-to-machine materials and aviation parts.
High-quality CNC machining tools for difficult-to-machine materials must have the characteristics of ultra-fine grain CNC machining tool substrates, cutting angles, high cutting edge strength, and surface coating heat resistance. Through the summary of past experience in the application of difficult-to-machine materials, reasonable selection of processing methods and process parameters is of great significance to the processing of such difficult-to-machine materials. The use of special processing technology is of great significance to improve processing efficiency and prolong the life of CNC machining tools.
No matter which processing method is used, the purpose is to minimize the temperature on the tool tip and the workpiece on the workpiece, prevent the surface hardening of the processed workpiece and the temperature of the tool tip from being too high, increase the heat dissipation area, and control the processing force . For example, the use of cycloidal cutting, high-feed milling and other methods can improve the processing efficiency of CNC machining and prolong the service life of CNC machining tools.
There is also sufficient cooling, suitable processing line speed, effective chip disposal, and reasonable NC machining wrap angle are very effective in controlling the temperature of the tool tip. For CNC machine tools and CNC machining tools with internal cooling function, the internal cooling function that is most conducive to cooling should be used as much as possible, so that the strong high-pressure water flow can take away a large amount of processing heat energy and ensure that the processing area remains within a certain temperature range. Even for machining equipment without internal cooling function, it is recommended to use tool holders with external cooling and internal cooling, and at the same time increase the cooling pressure to improve the cooling effect.
Therefore, the correct use of CNC lathes and reasonable processing tools can process more precise hardware and precision parts.
