Hardware surface processing can be subdivided into: hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing, etc.
Hardware parts surface processing:
1, paint processing: hardware factory in the production of large pieces of finished hardware are used when the paint processing, through the paint processing hardware to avoid rust, such as: daily necessities, electrical shells, handicrafts, etc.
2, electroplating: electroplating is also the most common hardware processing a processing technology, through modern technology to the surface of the hardware electroplating, to ensure that the product does not occur under the long use of mold embroidery, electroplating processing common: screws, stamping parts, battery pieces, car parts, small jewelry, etc.
3, surface polishing processing: surface polishing processing is generally used in daily necessities for a long time, through the surface burr processing of hardware products such as: we produce a comb, comb is through the stamping of hardware, then the stamping out of the comb edge is very sharp, we have to polish the edge sharp part of the throw into a smooth face, so that in the process of use will not cause harm to the human body.
Hardware turning parts
Turning external round surface is the basic method of processing external round surface in hardware processing, the equipment used is lathe. In general machine shops, lathes account for about 40% of the total number of machine tools. Turning is the main method for roughing and semi-finishing the external cylindrical surface of various materials, and it is also the final finishing method for various materials that are not suitable for grinding.
In small batches, turning is generally carried out on ordinary lathes. For mass production, multi-tool semi-automatic lathes or automatic lathes are widely used. Large disc parts should be machined on a vertical lathe. Large long shaft parts should be machined on heavy horizontal lathes.
Turning external surface features are: 1, the tool is simple, manufacturing, sharpening and easy to install; 2, the cutting process is smooth, small fluctuations in cutting force, conducive to the use of high cutting speed, improve productivity; 3, machine tool versatility, can be processed in a clamping out of the outer circle, end face, bore, threads and chamfering, etc.. The mutual position accuracy between the surfaces is easy to ensure; 4, suitable for the finishing of non-ferrous metal parts.
Hardware processing process is based on the production needs of open material, open some, such as small parts production can go to the punching machine and then gong cutting or CNC processing, which is a lot in the glasses accessories, auto parts production. And do container: is to open the material after punching to go to the welding, and then for sanding after oil blasting, and then assembly of the accessories can be shipped. And for hardware small accessories also a lot of sanding after the surface treatment, electroplating or oil spraying. Then burnishing or playing screws assembly packaging shipments.
