CNC post-processing
The hardware surface processing subdivision can be divided into: hardware oxidation processing, hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing, etc.
Surface processing of hardware parts:
1. Oxidation processing: When the hardware factory produces hardware products (mainly aluminum parts), they use oxidation processing to harden the surface of the hardware products and make them less prone to wear.
2. Spray painting processing: The hardware factory adopts spray painting processing when producing large-scale hardware products, and the hardware parts are prevented from rusting through painting processing, such as: daily necessities, electrical shells, handicrafts, etc.
3. Electroplating: Electroplating is also the most common processing technology for hardware processing. Electroplating on the surface of hardware parts through modern technology ensures that the products will not be mildewed or embroidered under long-term use. Common electroplating processing includes: screws, stamping parts, Batteries, car parts, trinkets, etc.
4. Surface polishing: Surface polishing is generally used in daily necessities for a long time. By performing surface burr treatment on hardware products, for example: we produce a comb. It is very sharp, we need to polish the sharp parts of the corners into a smooth face, so that it will not cause harm to the human body during use.
The processing method of the surface of CNC machined parts first depends on the technical requirements of the machined surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing, and sometimes they may be higher than the requirements on the part drawing in some respects due to technological reasons. For example, due to the misalignment of the benchmarks, the processing requirements for the surface of some cnc workpieces are increased. 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 machined part are clarified, the final processing method that can guarantee the requirements can be selected accordingly, and the processing methods of several working steps and each working step can be determined. The selected machining method of CNC machining parts should meet the requirements of parts quality, good machining economy and high production efficiency. For this reason, the following factors should be considered when selecting 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 range is economical, and the machining accuracy in this range is the economic machining accuracy. For this reason, when selecting the processing method, the corresponding processing method that can obtain economical processing accuracy should be selected.
2. Consider the properties of the cnc workpiece material.
3. Consider the structural shape and size of the CNC workpiece.
4. To consider productivity and economic requirements. High-efficiency advanced technology should be used in mass production. It is even possible to fundamentally change the manufacturing method of the blank, which can reduce the labor of machining.
5. The existing equipment and technical conditions of the factory or workshop should be considered. When selecting the processing method, the existing equipment should be fully utilized, the potential of the enterprise should be tapped, and the enthusiasm and creativity of the workers should be brought into play. However, it should also be considered to continuously improve the existing processing methods and equipment, adopt new technologies and improve the technological level.
