CNC precision machining step sequence

Whether it is CNC precision processing or every thing we do in life, we must be orderly and orderly. This is the only way to make a product or thing more perfectly.

Just like the operation of CNC precision machining needs to be carried out in order. If CNC precision machining is not carried out in the order of operation, it is easy to cause machine failure during the process, and personal safety will occur in serious cases. Therefore, when we do CNC precision processing, employees must pay attention to the safe operation sequence to avoid accidents!

A CNC precision machining often requires several surfaces. These surfaces not only have certain accuracy requirements, but also have certain position requirements for each surface. In order to meet these accuracy requirements, the machining sequence of CNC precision machining of each surface cannot be arranged at will, but must be followed by a certain processing order. This is the selection and conversion of positioning references determine the processing order, and the previous process prepares the positioning references for the subsequent process. principle.

The first thing to do is to prepare for the startup

After each startup or emergency stop reset of the machine tool, the cnc CNC machine tool first returns to the machine tool reference zero position (that is, return to zero), so that the machine tool has a reference position for its subsequent operations.

The second step is to be precise first and then operate

CNC precision machining As an accurate surface, it should be processed at the beginning of the CNC machining process, because it should be used to locate other surfaces in subsequent processes.

Step 3: Precise positioning of rough base

When CNC precision machining accurate surfaces, it is necessary to use a rough base to accurately locate them. In single-piece, small-batch production, or even batch production, for castings and forgings with complex shapes or large sizes, as well as blanks with large size errors, the marking process should be arranged before the machining process to ensure precise processing. Provide a corrective benchmark.

The fourth step is to require more accurate processing of CNC processing

After we have finished the precise processing, we will then roughly process, semi-finish and finish the main surfaces with high accuracy requirements. Surfaces with particularly high accuracy requirements also require photo finishing.

Step 5 Adjustment

CNC precision machining Before processing important surfaces, accuracy should be rectified once to ensure the processing accuracy of important surfaces.

Finally, the scrap process

For processes that are prone to waste during CNC processing , finishing and finishing can be placed in front, and some minor surface processing can be placed behind.
