CNC machining is also called CNC milling machine. The general milling machine is developed on the basis of numerical control processing. The two processing technologies are basically the same, and the structure is also somewhat similar. Under the control of the numerical control processing integrated digital control system of the general milling machine, the code can be controlled more accurately.
In addition to the features of ordinary milling machine, it also has the following features:
1。 The NC machining part has strong adaptability, flexibility, and can shape the contour shape, especially complex or difficult to control the size of parts, such as mold parts, shell parts, etc.
2。 CNC can process parts that cannot be processed, and also can process machines of ordinary machine tools, such as complex curve parts described by mathematical models and three-dimensional space surface parts.
3. CNC can be used to process parts requiring multi-channel processing after clamping and positioning.
4. Numerical control machining has high precision, stable and reliable machining quality, and it also avoids operator's operation mistakes.
5。 NC processing has a high degree of automation, which can reduce the labor intensity of operators. It is conducive to automation of production management.
6。 High production efficiency. NC machining generally does not require the use of special process equipment such as special fixtures. When replacing workpieces, it is only necessary to call and store the data of clamping tools and adjusting tools in the processing of CNC equipment, thus greatly reducing the production cycle.
Secondly, CNC machining and milling machine, boring machine and drilling machine functions make them highly centralized and greatly improve production efficiency. In addition, the spindle speed and feed speed of NC machining are infinitely variable, which is conducive to selecting the best cutting amount of Z.
