Hardware parts surface processing:
1. Spray painting processing: Hardware factories in the production of large pieces of finished hardware are used in the spraypainting process, through the spray painting process to make the hardware to avoid rust, such as: daily necessities, electrical appliances shells, artware and so on.

2.Electroplating：Electroplating is one of the most common processing techniques in hardware processing, through modern technology, the surface of hardware is electroplated to ensure that the products are not moldy and rusty under long time use, the common electroplating processing are: screws, stamping parts, battery plates, auto parts, trinkets and so on.

3.Surface Polishing Process: Surface Polishing Process is generally used in daily necessities for a long time, by burring the surface of hardware products such as: we produce a comb, comb is made of hardware through the stamping,and the corners of the stamped comb are very sharp,so we need to polish the sharp corners into a smooth surface, so that it will not cause harm to the human body during use.

4.Cylindrical Turning is the basic method of machining Cylindrical surface in hardware processing, the equipment used is a lathe. In the general machine shop, lathe accounted for about 40% of the total number of machine tools. Turning is the main method of roughing and semi-finishing of the external surface of various materials, and is also the final finishing method of various materials that are not suitable for grinding.

5.Single piece of small batch production, cylindrical turning is generally carried out in the ordinary lathe. When mass production, widely used multi-tool semi-automatic lathe or automatic lathe. Large disc-type parts should be processed on vertical lathe. Large long shaft parts need to be processed on heavy-duty horizontal lathes

6.The characteristics of turning cylindrical surfaces are:
(1) Simple tooling, easy to manufacture, sharpen and install.
(2) The cutting process is smooth and the cutting force fluctuation is small, which is conducive to the use of high cutting speed and improved productivity.
(3) The machine tool has good versatility and can process outer circles, end faces, inner holes, threads and chamfers in one clamping. The mutual position accuracy between surfaces is easy to ensure
(4) Suitable the fine finishing of non-ferrous metal parts.
