1. NC machining can process workpieces with complex surfaces
On CNC machine tools, the shape of the processed parts mainly depends on the processing program, and very complex workpieces can be processed.
2. CNC machining has high precision and stable quality
The accuracy of the CNC machine tool itself is higher than that of the ordinary machine tool. The positioning accuracy of the general CNC machine tool is 0.01 mm, and the repeated positioning accuracy is 0.005 mm: moreover, in the processing process of the CNC machine tool, the operator does not participate, so the human error of the operator is eliminated, and the processing degree of the workpiece is guaranteed by the CNC machine tool. Because the CNC processing adopts the centralized process, the impact of multiple clamping of the workpiece on the processing degree is reduced • based on the above points, CNC machining workpiece has high precision, good dimensional consistency and stable quality.
3. High productivity of numerical control processing
NC machining can effectively reduce the processing time and auxiliary time of parts. Because the spindle speed and feed speed of the NC machine tool are fast and fast, the machining time of parts can be reduced by reasonably selecting the cutting parameters and giving full play to the cutting performance of the tool • in addition • NC machining generally adopts general-purpose or combined fixtures, so there is no need to scribe before NC machining, and automatic tool change can be carried out in the machining process, which reduces the auxiliary time.
4. NC machining improves working conditions
The main tasks of those who are engaged in processing on CNC machine tools are to write programs, input programs, load and unload parts, prepare cutting tools, observe the processing state, and inspect parts, so the labor intensity is greatly reduced. In addition, CNC machine tools are generally closed processing, clean and safe, which improves the working conditions.
5. Numerical control processing is conducive to the modernization of production management
6. NC machining is the foundation of advanced manufacturing technology.
