Correct use of CNC machining tools

There are many 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, what kind of material is used for engraving and milling, and what kind of tool is used to process a good product, it is very important to have a good tool.

CNC machining (cnc CNC lathe machining) requires not only whether the tool is sharp, but also whether the model, size, material, and parameters of the tool are appropriate, which will affect the engraving process. Milling quality and efficiency.

Reasonable selection of tools in CNC machining, optimization of processing methods, to improve processing efficiency and prolong tool life, especially for difficult-to-machine materials and aerospace parts Even more so in processing.

High-quality CNC machining tools for difficult-to-machine materials must have ultra-fine grain CNC machining tool substrates, cutting angles, high cutting edge strength, and surface coatings Heat resistance and other characteristics. By summarizing the application experience of difficult-to-machine materials in the past, the 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 the processing efficiency and prolong the life of CNC machining tools. .

No matter which machining method is used, the purpose is to minimize the temperature of the tool tip on the workpiece and the workpiece on the workpiece, and prevent the surface of the workpiece to be hardened And the temperature of the tool tip is too high, increase the heat dissipation area, and control the processing force. For example, the use of trochoidal 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 machining line speed, effective chip treatment, and reasonable CNC machining wrapping angle is very effective to control the temperature of the tool tip. For CNC machine tools and CNC machining tools with internal cooling function, the most favorable internal cooling function 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 is kept within a certain temperature range. Even for machining equipment without internal cooling function, it is recommended to use a tool holder with external cooling and internal cooling, and at the same time increase the cooling pressure and improve the cooling effect.

Therefore, the correct use of CNC lathes and reasonable machining tools can process more precise hardware products and precision parts.
