The subdivision of hardware surface processing can be divided into: hardware oxidation processing, hardware spray painting processing, electroplating, surface polishing processing, hardware corrosion processing, and so on
Surface processing of hardware parts:
1. Oxidation processing: When producing hardware products (mainly aluminum parts), hardware factories use oxidation processing to make the surface of the hardware products harder,
Make it less susceptible to wear and tear.
2. Spray painting processing: Hardware factories use spray painting processing to produce large hardware products, which helps prevent rusting of the hardware,
For example: daily necessities, electrical casings, handicrafts, etc
3. Electroplating: Electroplating is also the most common processing technology in hardware processing. Through modern technology, the surface of hardware components is electroplated to ensure product length
Under the use of time, there will be no mold or embroidery. Common electroplating processes include screws, stamped parts, battery cells, car parts, small accessories, and so on
4. Surface polishing processing: Surface polishing processing is generally used for a long time in daily necessities, by treating surface burrs on hardware products, such as:
We produce a comb, which is a hardware component made by stamping. The edges and corners of the stamped comb are very sharp, so we need to
Polish the sharp edges and corners to create a smooth face, so as not to cause harm to the human body during use.
The surface processing method of CNC machining parts first depends on the technical requirements of the machining surface. But it should be noted that these technical requirements may not necessarily be just parts
The requirements specified in the diagram may sometimes be higher than those on the part diagram in some aspects due to technological reasons. If raised due to non overlapping benchmarks
Requirements for surface machining of certain CNC machined parts. Or, due to being used as a precision benchmark, higher processing requirements may be placed on it.
After clarifying the technical requirements for the surface of each CNC machining part, the final machining method that can ensure this requirement can be selected based on it, and the number of required methods can be determined
Steps and processing methods for each step. The selected CNC machining method should meet the quality of the parts, good machining economy, and
The requirement for high production efficiency. Therefore, when choosing a processing method, the following factors should be considered:
1. Any CNC machining method can achieve a considerable range of machining accuracy and surface roughness, but only in a narrow range
The scope is economic, and the machining accuracy within this range is economic machining accuracy. Therefore, when selecting the processing method, the corresponding selection should be made
A processing method that can achieve economic processing accuracy.
2. Consider the properties of the CNC machining material.
3. Consider the structural shape and size of CNC machined parts.
4. Consider productivity and economic requirements. When producing in large quantities, high-efficiency advanced processes should be adopted. It can even fundamentally change the raw material
The manufacturing method can reduce the amount of labor involved in mechanical processing.
5. It is necessary to consider the existing equipment and technical conditions of the factory or workshop. When selecting processing methods, existing equipment should be fully utilized to tap into the potential of the enterprise and unleash its potential
The enthusiasm and creativity of workers. But it is also necessary to consider continuously improving existing processing methods and equipment, adopting new technologies, and improving process levels.
