What are the rules of CNC machining high-precision parts?

There are strict regulations on the process flow of high-precision parts processing. If you don't pay attention to it, the deviation of the product workpiece will exceed the dimensional tolerance, so it is necessary to reprocess or declare the blank damaged, which greatly increases the manufacturing cost. Therefore, today, let's talk about the regulations for processing high-precision parts, which can help you improve productivity.

The first is the specification level, which should be processed in strict accordance with the dimensional tolerance provisions of the engineering drawings. Although the dimensions of the parts manufactured by the company are not the same as those in the drawings, the specific dimensions are within the dimensional tolerance range of the basic theoretical specifications, which are all qualified products and can be used as parts.

The processing sequence allocation of high-precision CNC parts should be considered according to the structure and blank conditions of the parts, as well as the necessity of accurate positioning and clamping. The key is that the products and workpieces do not need to be damaged, the processing of the upper process cannot damage the market positioning and clamping of the lower process, and the processing technology of the general and high-precision parts that intersect in the middle should also be fully considered.

Carry out the process of adding internal shapes and internal walls, and then carry out the process flow of external design and processing. The same accurate positioning and clamping method or the same tool processing process can be connected and developed to reduce the frequency of repeated accurate positioning, tool changing, and pin shifting. For multiple processes carried out with the same equipment, the process with less damage to the rigidity of products and workpieces should be allocated first.

CNC machine tool processing technology has been widely promoted

Compared with manual processing by manufacturers, manual processing has great advantages, such as the accuracy and availability of parts manufactured by CNC machine tools; CNC machine tools can produce parts with complex designs that cannot be processed by hand. CNC machining technology has been widely promoted. Most machining workshops have the ability of CNC machining. The typical CNC machining methods of machining workshops include CNC machining center, CNC machining center, and wire EDM (wire EDM). The special tools for developing NC machining center are called CNC machine tools or CNC machine tool machining management center, The CNC lathe that performs cutting in the CNC machining center is called the CNC lathe management center. The G code processed by the CNC machine tool can be written manually, but generally, the cam (aided design and manufacturing) mobile phone software is used in the machining workshop to automatically load CAD (aided design and design scheme) documents and convert them into G code program flow to operate the CNC machine tool.

In the processing of machining center, the definition of machining line generally follows the following standards:

1. To ensure the accuracy and surface roughness of processed products.

2. Make the processing line shorter, reduce idle scheduling time, and improve processing efficiency.

3. Simplify the amount of labor of the numerical calculation method and simplify the process flow as much as possible.

4. For some re-use procedures, application segments should be used.
