1. Spray painting processing: the hardware factory adopts spray painting processing when producing large hardware finished products, which can prevent hardware from rusting
Such as: daily necessities, electrical enclosures, handicrafts, etc
2. Electroplating: electroplating is also the most common processing technology for hardware processing. The surface of hardware is electroplated through modern technology to ensure long product length
There is no mildew or embrittlement under the use of time. Common electroplating processes include: screws, stampings, battery chips, car parts, small accessories, etc,
3. Surface polishing: surface polishing is generally used in daily necessities for a long time. Through surface burr treatment on hardware products, for example, we
Produce a comb. The comb is a metal part made by pressing. The corners of the punched comb are very sharp
The sharp parts of the edges and corners will be polished into smooth faces, so that no harm will be caused to the human body during use.
Turning cylindrical surface is the basic method for metal processing, and the equipment used is a lathe. In general machinery plants, lathes account for the total number of machine tools
About 40% of the number. Turning is the main method for roughing and semi finishing the cylindrical surface of various materials, and it is also the final method for various materials that are not suitable for grinding
Finishing method.
In case of small batch production of single piece, the turning of cylindrical surface is generally carried out on an ordinary lathe. Multi tool semi-automatic lathes or automatic lathes are widely used in mass production
Lathe. Large disc parts shall be processed on vertical lathe. Large long shaft parts need to be processed on heavy horizontal lathe.
The characteristics of turning the cylindrical surface are: 1. The tool is simple, easy to manufacture, sharpen and install; 2. The cutting process is stable and the cutting force fluctuation is small, which is conducive to mining
Use high cutting speed to improve productivity; 3. The machine tool has good versatility, and can process the excircle, end face, inner hole, thread and chamfer in one clamping
Angle, etc. The mutual position accuracy between surfaces can be easily guaranteed; 4. It is suitable for finishing of nonferrous metal parts.
