Hardware surface processing can be divided into: metal oxidation processing, metal spray painting processing, electroplating, surface polishing processing, metal corrosion processing and so on

Surface processing of hardware parts:

1, oxidation processing: hardware factory in the production of finished hardware products (mainly aluminum) to use oxidation processing, hardware products surface hard, so that it is not easy to receive wear.

2, paint processing: the hardware factory in the production of large pieces of finished metal products are using paint processing, through the paint processing to avoid rust hardware, such as: daily supplies, electrical shells, crafts, etc

3. Electroplating: electroplating is also the most common processing technology for hardware processing. Through modern technology, electroplating on the surface of hardware parts can ensure that the products will not be moulded or embroidered for a long time.

4, surface polishing machining, surface polishing processing generally longer used in daily necessities, burrs treatment on the surface of a metal products such as: we produce a comb, comb is by stamping parts, stamping out comb edge is very sharp, we have to part by polishing the edges sharp thrown into the smooth face, so that in the process of use does not cause harm to human body.

The machining method of CNC machining surface first depends on the technical requirements of machining surface.However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing, and may be higher than the requirements in some aspects due to technological reasons.As a result of the benchmark does not coincide and improve the surface of some CNC machining requirements.Or higher processing requirements may be required as a result of being used as a precision benchmark.

When the technical requirements of each CNC workpiece surface are clear, the final processing method that can ensure the requirements can be selected accordingly, and several working steps and the processing method of each working step are determined.The CNC machining method selected should meet the requirements of parts quality, good processing economy and high production efficiency.To this end, the following factors should be taken into account when selecting processing methods:

1. There is a wide range of machining accuracy and surface roughness obtained by any CNC machining method, but only in a narrow range is economical, and the machining accuracy of this range is economical.Therefore, when selecting the processing method, the corresponding processing method that can obtain the economical processing precision should be selected.

2. Consider the properties of CNC machining materials.

3. The structural shape and size of CNC machining parts should be considered.

4. Consider productivity and economy requirements.Advanced processes with high efficiency should be used for mass production.It can even fundamentally change the manufacturing method of blank and reduce the labor of machining.

5. The existing equipment and technical conditions of the factory or workshop shall be taken into consideration. The selection of processing methods shall make full use of the existing equipment, tap the potential of the enterprise and give play to the initiative and creativity of the workers.However, consideration should also be given to continuous improvement of existing processing methods and equipment, adoption of new technologies and improvement of technological level.
