Machining is the utilization of energy, equipment, technology, information, and other resources in the fabrication of mechanical products to satisfy market demands and turn them into tools for general use. The purpose of machining surface treatment is to deburr, degrease, remove welding spots, remove scale, and clean the surface of workpiece materials in order to increase product corrosion resistance, wear resistance, decoration, and other functions throughout the manufacturing process.
Numerous sophisticated mechanical processing technology approaches have increasingly surfaced as a result of the current mechanical processing technology’s quick development. What are the machining surface treatment procedures? What sort of surface treatment procedure can produce the desired outcomes in small batches, at a cheap cost, and with minimal effort? Major production industries are seeking a solution to it immediately.
Cast iron, steel, and non-standard mechanically designed low-carbon steel, stainless steel, white copper, brass, and other non-ferrous metal alloys are frequently used for machining parts. These alloys call for specialized mechanical design to address issues. They also contain plastics, ceramics, rubber, leather, cotton, silk, and other non-metallic materials in addition to metals. Materials have diverse properties, and the manufacturing process is also extremely different.
Metal surface treatment and non-metal surface treatment are two categories under which the mechanical processing’s surface treatment falls. Sandpaper is used as part of the non-metal surface treatment process to remove surface oils, plasticizers, release agents, etc. Mechanical treatment, electric field, flame, and other physical procedures to remove surface stickies; flame, discharge, and plasma discharge treatments are all options.
The method for treating the surface of metal is: One method is anodizing, which forms an aluminum oxide film on the surface of aluminum and aluminum alloys using electrochemical principles and is appropriate for treating the surfaces of aluminum and aluminum alloys; 2 Electrophoresis: This straightforward procedure is suitable for materials made of stainless steel and aluminum alloys after pretreatment, electrophoresis, and drying; 3PVD vacuum plating is appropriate for coating cermet because it uses the technology of depositing thin layers throughout the logistics process; 4Spray powder: employ powder spraying equipment to apply powder coating to a workpiece’s surface; this technique is frequently used for heat sinks and architectural furniture products; 5 Electroplating: by affixing a metal layer to the metal surface, the workpiece’s wear resistance and attractiveness are improved; ⑥ Various methods of polishing include mechanical, chemical, electrolytic, ultrasonic, Surface roughness of the workpiece is decreased via fluid polishing, magnetic grinding, and polishing employing mechanical, chemical, or electrochemical processes.
The magnetic grinding and polishing method, used in the aforementioned metal surface treatment and polishing process, not only has a high polishing efficiency and good grinding effect, but is also simple to use. Gold, silver, copper, aluminum, zinc, magnesium, stainless steel, and other metals are among the materials that can be polished. It should be noted that iron is a magnetic material, which prevents it from having the desired cleaning effects for precision small parts.
Here is a summary of the brief series on the machining process’ surface treatment step. In conclusion, the machining surface treatment is mostly influenced by the material’s qualities, the polishing equipment’s technical operation, and the application of the components.
