What Are The Classifications Of Surface Processing Of Hardware Parts?

1, spray painting processing: hardware factory in the production of large hardware products are using spray painting processing, through the spray painting processing to avoid rust hardware, such as: daily supplies, electrical shell, crafts and so on.

2, electroplating: electroplating is also the most common hardware processing of a processing technology, through modern technology on the surface of hardware plating, to ensure that products for a long time use without mildew embroidery, electroplating processing is common: screws, stamping parts, battery pieces, car parts, small accessories and so on.

3, surface polishing processing: surface polishing processing is generally used in daily necessities for a long time, through the surface burr treatment of hardware products, such as: We produce a comb. The comb is made of stamped hardware. The corners of the stamped comb are very sharp.

Turning outer round surface is the basic method of hardware processing and the equipment used is lathe. In general machinery factories, lathes account for about 40% of the total number of machine tools. Turning is the main method of rough and semi-finish machining the outer surface of various materials, and also the final finishing method of various materials that are not suitable for grinding.

In small batch production of a single piece, turning the outer round surface is usually carried out on a common lathe. Multi-tool semi-automatic lathes or automatic lathes are widely used in mass production. Large disk parts should be processed on vertical lathes. Large long shaft parts need to be machined on heavy horizontal lathes.

The characteristics of turning the outer round surface are: 1, the tool is simple, manufacturing, grinding and installation is convenient; 2, the cutting process is stable, the cutting force fluctuation is small, is conducive to the use of high cutting speed, improve productivity; 3, the machine has good versatility, can be processed in a clamping outer circle, end face, inner hole, thread and chamfer. The accuracy of mutual position between the surfaces is easy to ensure; 4. Suitable for the finishing of non-ferrous metal parts.
