Industry Outlook and Machining Process Analysis on CNC Machining

Nowadays, CNC machining is becoming more and more popular in the market, and many high-precision machining technologies are emerging. What direction will CNC precision parts machining develop in the future, which is probably the most concerning issue?

CNC machining industry outlook and prospect

Daily automation

Like many great technologies in history, CNC machining will continue to grow and develop. Its uses have expanded to many markets and industries, such as medical equipment and aerospace, and will continue to expand.

CNC machining has a broad development prospect in the field of process automation. In other words, tasks that were once completed by hand may soon be completed in a more ideal environment through CNC. For example, etching or painting can be a task that can be more accurately accomplished by machines. Or, consider that in the near future, the simplest tasks can be automated with just a button.

Product development solutions

We fully understand the potential of CNC machining. CNC machining China factory uses them every day to develop and manufacture many products and components that are used throughout the country.

How to divide the CNC machining process?

The division of the CNC machining process can generally be carried out according to the following methods:

  • Concentrated sequencing method: According to the tool used to divide the process, use the same tool to complete all parts of the part that can be completed by CNC machining. Then use the second and third tools to complete the other parts they can complete. This can reduce the number of tool changes, compress the air travel time, and reduce unnecessary positioning errors.

  • Sequencing method by machining parts: For parts with a lot of CNC machining content, the machining parts can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc. Generally, the plane and positioning surface are machined first, and then the holes are machined; the simple geometric shapes are machined first, and then the complex ones; the parts with lower precision are machined first, and then the parts with higher precision.

  • Sequencing method of rough and precise CNC machining: For parts that are prone to deformation during rough machining and need to be corrected, it is generally necessary to separate the processes if rough and precise machining is required.

In summary, when dividing the process, we must flexibly grasp the structure and processability of the parts, the function of the machine tool, the amount of CNC machining content of the parts, the number of installations, and the production organization status of our unit. It is recommended to use the principle of process concentration or process dispersion according to the actual situation, but we must strive for rationality.

What principles should be followed for the arrangement of the CNC machining sequence?

The arrangement of the machining sequence should be considered based on the structure and blank condition of the parts, as well as the need for positioning and clamping, with the focus on not destroying the rigidity of the workpiece. The sequence should generally follow the following principles:

  • The machining of the upper process cannot affect the positioning and clamping of the subsequent process, and the machining processes with general-purpose machine tool should also be comprehensively considered.

  • The machining of internal shapes and cavities should be carried out first, followed by the machining of external shapes.

  • Processes that are machined using the same positioning and clamping method or the same tool are best connected to reduce the number of repeated positioning times, tool changes, and pressure plate movements.

  • Multiple processes that are carried out in the same installation should arrange the processes that cause less damage to the rigidity of the workpiece first.
