General CNC machining usually refers to computer digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. CNC is also called computer gong, CNCCH or CNC machine tool. It is a new type of processing technology, and its main work is to compile processing programs, that is, to convert the original manual work into computer programming. Of course, manual processing experience is required.
CNC machining has the following advantages:
1. The adaptability of CNC machining parts is strong. The coordination ability is good, and it can process parts with complex contour shapes or unmanipulated specifications, such as mold shell parts, shell parts, etc.;
2. CNC machining can process parts that cannot be machined by ordinary CNC lathes or are difficult to process, such as complex curve parts described by mathematical analysis models and their three-dimensional space slope parts;
3. CNC machining can process parts that need to be processed in multiple processes after one clamping and precise positioning;
4. CNC machining has high precision and reliable machining quality. The single pulse dose of CNC machine tools is generally 0.001mm, and high-precision CNC machine tools can reach 0.1μm. In addition, CNC machine tool processing also prevents the actual operation staff. wrong operation;
5. The high level of manufacturing automation technology can ease the labor efficiency of operators. Conducive to enterprise production management automation technology;
6. High production efficiency. CNC milling machines generally do not need to use special process technologies such as special fixtures. When replacing product workpieces, only the processing program flow stored in the CNC machine tool equipment needs to be activated. Special tools for clamping and adjustment of CNC blade data information can, thus greatly shortening the production cycle. Secondly, the CNC milling machine has the functions of CNC lathe, milling machine and planer, which can concentrate the process flow and further improve the productivity. In addition, the spindle bearing speed ratio and tool feed rate of the CNC milling machine are all infinitely variable, which is conducive to the selection of better tool durability.
The disadvantage of CNC machining is that the mechanical equipment is expensive, and the maintenance personnel are required to have high quality.
