Hardware precision mechanical processing can be divided into: hardware oxidation processing, hardware spray painting processing, electroplating, surface polishing processing, hardware corrosion processing, and so on
Hardware parts CNC lathe processing:
1. Oxidation processing: When producing hardware products (mainly aluminum parts), hardware factories use oxidation processing to make the surface of the hardware products hard and less prone to wear and tear.
2. Spray painting processing: Hardware factories use spray painting processing when producing large hardware products to prevent rusting, such as daily necessities, electrical enclosures, handicrafts, etc
3. Electroplating: Electroplating is also the most common processing process in hardware processing. Through modern process skills, the surface of hardware components is electroplated to ensure that the product does not produce mold or embroidery during long-term use. Common electroplating processes include screws, stamping 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. For example, we produce a comb, which is a hardware component made by stamping. The edges and corners of the stamped comb are very sharp. We need to polish the sharp parts of the edges and corners to lubricate the face, so that they will not cause damage to the human body during use.
The processing method for the appearance of CNC machined parts mainly depends on the skill requirements for processing the appearance. However, it should be noted that these skill requirements may not necessarily be the requirements specified on the part drawing, and sometimes may be higher than the requirements on the part drawing in some aspects due to technological reasons. If the processing requirements for the surface of certain CNC machining parts are improved due to non overlapping benchmarks. Or higher processing requirements may be placed on it because it is used as a precision benchmark.
After clarifying the skill requirements for the appearance of each CNC machining part, the final processing method that can ensure this requirement can be selected based on it, and the number of steps required and the processing method for each step can be confirmed. The selected CNC machining method should meet the requirements of component quality, outstanding machining economy, and high production power. Therefore, when selecting processing methods, the following factors should be considered:
1. Any CNC machining method can achieve a considerable scale of machining accuracy and surface roughness, but only on a narrow scale is economic, and the machining accuracy of this scale is economic machining accuracy. Therefore, when selecting processing methods, corresponding processing methods that can achieve economic processing accuracy should be selected.
2. Consider the nature of CNC machining data.
3. Consider the structural shape and size of CNC machined parts.
4. We need to consider production rate and economic requirements. When producing in large quantities, advanced processes with high power should be selected. Even the ability to fundamentally modify the manufacturing method of raw materials can reduce the amount of labor involved in mechanical processing.
