What are the advantages and disadvantages of CNC machining?
With the development of manufacturing industry, many precision parts are now processed by CNC. So why is CNC machining so popular? Because CNC processing is not only easy to operate, but also good processing effect.
1.Advantages of CNC processing:
①CNC can process automatically
CNC machining usually refers to the precision machining controlled by computer numbers. Therefore, it can be controlled by the program instructions of CNC machine tools, and the whole machining process is carried out automatically according to the program instructions. Machine tool automation degree is high, greatly reduce the labor intensity of workers.
Currently, many CNC machines can operate unattended throughout the manufacturing cycle, freeing up time for other tasks. This provides a number of side benefits for CNC users, including reduced operator fatigue, reduced error due to human error, and consistent and predictable processing times for each workpiece. to
②CNC machining accuracy is high
The second major advantage of CNC technology is the consistency and precision of the workpiece. The typical precision of today’s CNC machines has reached two to four thousandths of an inch or 0.05 to 0.10 mm, with repeatability close to or better than eight thousandths of an inch or 0.02 mm. This means that once the program is proven, it can easily produce two, ten, or a thousand identical parts with the same precision and consistency. Can realize mass production, product quality is easy to control.
③CNC machining flexibility
Since these machines are run by computer programs, running different artifacts is as easy as loading different programs. to
This also brings another benefit, namely fast conversion. Because these machines are so easy to set up and run, and can easily load programs, their setup time is very short.
④CNC machining efficiency is high
CNC machining can be multi-coordinate linkage, processing complex zero. When the shape and size of parts need to be changed, only the NC program needs to be changed, saving production preparation time.It can process complex profiles that are difficult to be processed by conventional methods, and can even process some parts that cannot be observed.
In the case of multi-variety, small batch production, the production efficiency is higher, which can reduce the time for production preparation, machine adjustment and process inspection, and reduce the cutting time due to the use of optimal cutting volume.
