What is the classification of hardware processing?

Usually, there are only two categories of hardware: large hardware and small hardware. Large hardware refers to steel plates, steel bars, flat iron, universal angle, channel iron, I-beam iron and various types of steel materials, small hardware for the construction hardware, white iron, locks, nails, wire, steel wire mesh, steel wire scissors, home hardware, various tools and so on. On the nature and use of hardware, should be divided into iron and steel materials, non-ferrous metal materials, mechanical parts, transmission equipment, auxiliary tools, working tools, construction hardware, home hardware and other eight categories. Hardware processing can also be called metal processing. Turning milling planing grinding boring, etc., modern processing increased electrical discharge machining, etc.. In addition, die-casting, forging, etc. are also commonly used means of processing. If it simply involves sheet metal, then commonly used is milling, grinding, wire cutting (discharge a class) and heat treatment. Hardware processing can be divided into: automatic lathe processing, CNC processing, CNC lathe processing, five-axis lathe processing, according to the general can be divided into: hardware surface processing, hardware molding processing of two categories. Hardware surface processing can be subdivided into: hardware paint processing, electroplating, surface polishing processing, hardware corrosion processing and so on.

1, paint spraying: At present, hardware factories use paint spraying in the production of large pieces of finished hardware to avoid rusting, such as: daily necessities, electrical appliances, crafts and so on.

2, electroplating: electroplating is also the most common hardware processing a processing technology, through modern technology on the surface of the hardware plating, to ensure that the product is not used for a long time to ensure that the mold and embroidery, electroplating processing of the common: screws, stamping parts, battery tabs, car parts, trinkets and so on.

3, surface polishing: surface polishing is generally used in daily necessities for a long time, through the surface burr processing of hardware products, the sharp edges and corners of the part thrown into a smooth face, so that the use of the process will not cause harm to the human body.
