- 1. High degree of automation When processing parts on a CNC machine tool, all machining processes are completed automatically except for the second-hand L clamping blank, which reduces the labor intensity of the operator and improves the working conditions.
- 2. Strong adaptability to the processing object The control information for automatic processing on the CNC machine tool is provided by paper tape, or manually input the control machine through the keyboard. When adding one or a few objects to change, in addition to correspondingly replacing the tool and solving the blank In addition to the clamping method, as long as the processing program and paper tape of the part are reprogrammed, new parts can be automatically processed without any complicated adjustments to the machine tool. This not only saves a lot of special tools, prototypes and standard prototypes, but also shortens the production preparation cycle. In view of the characteristics of frequent aerospace product modification and short trial production cycle requirements, the CNC machining method has special advantages.
- 3. High machining accuracy and stable machining quality The dimensional accuracy of CNC machining is usually between 0. CC5 and 0.1 mm, and is not affected by the complexity of the part shape. Processing eliminates the operator’s artificial variance, improves the consistency of parts in the same batch, and keeps product quality stable. This provides favorable conditions for improving production, assembly quality and work efficiency, and the scrap rate of parts is greatly reduced.
- 4. With high production efficiency. The efficiency of CNC machining is high. On the one hand, it is due to the high degree of automation of CNC machine tools. On the other hand, the process of scribing, multiple clamping and positioning, inspection and other processes is omitted during the processing process. Increased productivity.
- 5. Easy to establish computer communication network. Because CNC machine tool uses digital information, it is easy to connect with computer-aided design system, forming an integrated system with close integration of computer-aided design and manufacturing.
