What are the steps of CNC precision machining

Let's take a look at the process steps of CNC precision machining.

 

Firstly, considering the placement requirements of CNC precision machining processes based on the requirements of part layout, vacancies, and positioning clamping. The rigidity of the components will not be damaged.

 

1. The processing of the initial process should not affect the positioning and clamping of the next process, and the processing technology of ordinary tight parts should also be considered at the middle intersection.

 

2. Before the formal processing process, it is recommended to use excellent internal processing techniques.

 

3. By using similar positioning and clamping methods or similar tool processing processes, deviations can be effectively avoided, processing compliance can be improved, and the number of repeated positioning and tool changes, as well as the number of times the pressing plate can be moved.

 

4. Multiple processes during installation should first place the process that causes less rigid damage to the parts.

Secondly, the skill of dense tool sorting and strict part processing requirements require separate processing of the required tools. Using the same tool to process parts can achieve one-sided, and then using the second and third tools to achieve other one-sided, which can effectively reduce tool change time, compress space distance time, and reduce unnecessary positioning deviation;

Thirdly, sort according to the processing site. For products with a large processing content, CNC precision machining can be divided into several aspects based on their layout characteristics, such as internal shape, form, curved surface, or plane. Generally, the plane and positioning surface are processed first, followed by the hole. A simple geometric style is given first, and then complex geometric styles are processed. The low positioning parts are excellent, and then the high positioning requirements are processed.
