CNC post processing

The subdivision of hardware surface processing can be divided into: metal oxidation processing, metal spray painting processing, electroplating, surface polishing processing, metal corrosion processing, etc.
 

Surface processing of hardware parts:

 

1. Oxidation processing: When the hardware factory produces hardware products (mainly aluminum parts), it adopts oxidation processing to make the surface layer of the hardware products hard.

 

Make it less prone to wear.

 

2. Paint spraying processing: The hardware factory adopts paint spraying processing when producing large pieces of finished hardware, so as to prevent the hardware from rusting through paint spraying processing.
 

 

For example: daily necessities, electrical enclosures, crafts, etc.
 

3. Electroplating: Electroplating is also the most common processing technology for hardware processing. The surface of hardware is electroplated through modern technology to ensure long product life.

 

There is no mildew and embroidering under the time of use. The common electroplating processes are: screws, stamping parts, batteries, car parts, small jewelry, etc.

 

4. Surface polishing process: Surface polishing process is generally used in daily necessities, through the surface burr treatment of hardware products such as:

 

We produce a comb, the comb is made of stamping hardware, then the corner of the comb is very sharp, we need to

 

The sharp parts of the corners are thrown into a smooth face by polishing, so that it will not cause harm to the human body during use.

 

The method of machining the surface of cnc machined parts depends on the technical requirements of the machined surface. But it should be noted that these technical requirements are not necessarily parts

 

The requirements stipulated in the drawings may sometimes be higher than the requirements on the parts drawings due to technical reasons. E.g. increased due to non-coincidence of benchmarks

 

The processing requirements for the surface of certain CNC machining parts. Or because it is used as a precision benchmark, it may put forward higher processing requirements.

 

When the technical requirements of the surface of each cnc processed part are clarified, the final processing method that can guarantee the requirements can be selected accordingly, and it is determined that several

 

Working steps and processing methods of each working step. The selected cnc processing method should meet the quality of parts, good processing economy and The requirement of high production efficiency. For this reason, the following factors should be considered when choosing a processing method:

 

1. The machining accuracy and surface roughness that can be obtained by any cnc machining method have a considerable range, but only in a narrow one The range is economic, and the processing accuracy in this range is the economic processing accuracy. Therefore, when selecting the processing method, the corresponding The processing method that can obtain economical processing accuracy.

 

2. To consider the nature of cnc processed parts material.
 

3. To consider the structural shape and size of cnc processed parts.
 

4. To consider productivity and economic requirements. When mass production is in mass, advanced and efficient processes should be used. You can even fundamentally change the rough the manufacturing method can reduce the labor of mechanical processing.

 

5. It is necessary to consider the existing equipment and technical conditions of the factory or workshop. When selecting the processing method, the existing equipment should be fully utilized to tap the potential of the enterprise and play

 

The enthusiasm and creativity of the workers. But we should also consider continuously improving the existing processing methods and equipment, adopting new technologies and improving the level of technology.
