The processing of hardware by Dongguan hardware processing factories can be further classified into: hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing, etc

1. Spray painting processing: When manufacturing large hardware products, Dongguan hardware processing factories all adopt spray painting processing. Through spray painting processing, hardware parts can prevent rusting, such as daily necessities, electrical appliance shells, handicrafts, etc

2. Electroplating: Electroplating is also one of the most common processing techniques in hardware manufacturing. By using modern technological processes to electroplate the surface of hardware parts, it ensures that the products do not mold or rust during long-term use. Common electroplating processing includes: screws, stamped parts, battery cells, turned parts, small ornaments, etc.

3. Surface polishing processing: Surface polishing processing is generally used in daily necessities for a long time. It involves surface burr treatment of hardware products, such as: We produce a comb. The comb is a hardware part formed by stamping. The edges and corners of the stamped comb are very sharp. We need to polish the sharp parts of the edges and corners to make them smooth. Only in this way can it not cause harm to the human body during use.

Turning the outer cylindrical surface is the basic method for processing outer cylindrical surfaces in metalworking, and the equipment used is a lathe. Among general hardware processing factories, lathes account for about 40% of the total number of machine tools. Turning is the main method for rough and semi-finishing the outer cylindrical surfaces of various materials, and it is also the final finishing method for various materials that are not suitable for grinding.

When performing single-piece and small-batch production, turning the outer cylindrical surface is generally carried out on a conventional lathe. When mass-producing, multi-tool semi-automatic lathes or automatic lathes are widely used. Large disc-shaped parts should be processed on vertical lathes. Large long shaft parts need to be processed on heavy-duty horizontal lathes.

The characteristics of turning the outer cylindrical surface are:

1. The cutting tools are simple, easy to manufacture, sharpen and install.

2. The cutting process is smooth with small fluctuations in cutting force, which is conducive to adopting high cutting speeds and improving productivity.

3. The machine tool has good versatility and can process outer circles, end faces, inner holes, threads and chamfers, etc. in a single clamping. The mutual positional accuracy between each surface is easy to guarantee.

4. It is suitable for the fine processing of non-ferrous metal parts.
