Several common classification of metal parts processing Dongguan
Dongguan metal parts processing can be divided into segments: metal paint processing, plating, surface polishing processing, metal processing, and so corrosion.
1, paint processing: metal parts factory in Dongguan in the production of large pieces of hardware when they are finished using the paint processing, paint processing by making hardware avoid rusting, such as: daily necessities, electrical enclosures, and other crafts.
2, plating: plating metal processing is the most common kind of process, through modern technology for metal surface plating, to ensure product under prolonged use mildew rust does not occur, electroplating process common: screws, stamping parts, battery-chip, car parts, trinkets and so on.
3, the surface polishing process: surface polishing in commodities in general with a long, metal product by surface treatment such as Burr: We produce a comb, comb through the stamped metal parts, then punched out of the corner comb is very sharp, we have sharp edges by polishing the part thrown into a smooth face, so that the use of the process will not cause harm to humans.
Turning the outer surface of the basic metal processing method for processing an external circular surface, equipment used lathe. In general metal parts factory in Dongguan, turning about 40% of the total number of units of the machine. Turning is the main method for roughing and semi-finishing cylindrical surfaces of various materials, and it is not the ultimate method of finishing grinding of various materials.
Single and small batch production, turning the outer surface is generally carried out in the lathe. When mass production, widespread use of multi-tool lathe or semi-automatic lathes. Large disc-type parts should be processed in a vertical lathe. Large long shaft parts required in the heavy horizontal lathe processing.
Features turning cylindrical surface are: 1, the tool is simple, easy to manufacture, install and grinding; 2, smooth cutting process, cutting force fluctuation is small, in favor of using high cutting speeds and improve productivity; 3, machine tool common good, It can be processed cylindrical, face, bore, thread, and beveling in one clamping. Mutual positional accuracy between surfaces easy assurance; 4, suitable for non-ferrous metal parts finishing.
