With the development of economy, many factories have been using CNC machining operations. Numerical control machining appears as an innovative technology, with its main task being to process the program. This process involves converting an original manual work into computer programming, and directly and automatically manufacture any products and parts according to the program prepared by the technical personnel set. So, what are the advantages and disadvantages of CNC machining?
The Advantages of CNC Machining：
1、CNC automatic processing
CNC machining usually refers to precision machining controlled by computer, 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 tools function with a high degree of automation, greatly reducing the labor intensity of workers.
Currently, most CNC machines can operate unattended throughout the processing cycle, allowing the operator to free up time for other tasks. This also has several benefits, including reduced operator fatigue, reduced errors due to human mishandles, and consistent and predictable processing times for each workpiece.
2、High Accuracy of CNC Machining
The second advantage of numerical control technology is the consistency and accuracy of the workpiece. Today, the typical precision of CNC machines is two to four thousandths of an inch or 0.05 to 0.10 millimeters, which means that once the program is proven, it is easy to produce two, ten or a thousand identical parts with the same precision and consistency. The possibility of mass production can easily be achieved, and product quality can gain an easy control.
3、Flexibility of CNC Processing
Machines are run by computer programs, with running different artifacts being as easy as loading different programs. This also brings quick conversion benefits. Because these machines are so easy to set up and run, and can easily load programs, their setup time is very short.
4、High Efficiency of CNC Processing
CNC machining can realize multi-coordinate linkage, processing complex parts and so on. You only need to modify the CNC program to transform the shape and size of a part, thus saving production lead-up time.
5、It can process complex profiles that are difficult to be processed by traditional methods, and can even process some processing parts that cannot be observed.
6、This technique reaps more benefits in small batch production with the numerous varieties of parts being involved, and this technique is of high efficiency, greatly reducing the production preparation, machine tool adjustment , process inspection time, and cutting time when the amount of on-wait parts are set in a proportionate amount.
The Drawbacks of CNC Machining
- This technique involves high technical requirements for operators and machine maintenance personnel.
2. CNC machining route is not convenient to control, not as intuitive as ordinary machine tools.This technique involves high technical requirements for operators and machine maintenance personnel.
3. It is expensive to purchase machine tools and equipment.
