Do you know how to process precision metal parts?

u200bu200b Precision metal parts refer to the collective name of various specifications and shapes of metal blocks, metal rods, metal tubes, etc., made of metal materials. The materials of metal parts: steel and non-ferrous metals (or non-ferrous metals), steel: The alloy of iron with a carbon content of 2% to 4.3% is cast iron, and the alloy of iron with a carbon content of generally 0.03% to 2% is steel. In Fe-C alloys, various alloying elements are purposefully added to improve the strength, hardness, wear resistance and corrosion resistance of steel. Commonly used alloying elements are Si, Mn, Cr, Ni, Mo, W, V, Ti, Nb, B, etc., forming a variety of alloy cast iron or alloy steel. Processing Treatment Process 1) Anti-corrosion and anti-rust treatment: Boiling black and boiled blue treatment is also called phosphating treatment, so that metal parts have corrosion resistance and rust resistance. 2) Hardening treatment: The treatment method to increase the hardness of metal parts: 1. To increase the surface hardness of metal parts, use surface carburization, and the surface color will be black after carburization; 2. Quenching treatment can increase the hardness; 3. Vacuum heat treatment Improve the overall hardness. Processing technology Machining, stamping, precision casting, powder metallurgy, metal injection molding, laser processing, electric discharge processing, ultrasonic processing, electrolytic processing, particle beam processing and ultra-high-speed processing, etc. Similar to turning, milling, forging, casting, grinding, numerical control processing, CNC numerical control centers are all conventional machining processing. Casting Liquid metal is poured into a mold cavity that is compatible with the shape and size of the part, and it is cooled and solidified to obtain a production method of a blank or part. It is usually called liquid metal forming or casting. Process flow: liquid metal→filling→solidification shrinkage→casting
