1. Spray painting processing: The hardware factory adopts spray painting processing when producing large-scale hardware products, and the hardware parts are prevented from rusting through painting processing, such as: daily necessities, electrical shells, handicrafts, etc.
2. Electroplating: Electroplating is also the most common processing technology in hardware processing. Electroplating on the surface of hardware parts through modern technology ensures that the products will not be mildewed and embroidered under long-term use. Common electroplating processing includes: screws, stamping parts, Batteries, car parts, trinkets, etc.
3. Surface polishing: Surface polishing is generally used in daily necessities for a long time. By carrying out surface burr treatment on hardware products, for example: we produce a comb. It is very sharp, we need to polish the sharp parts of the corners into a smooth face, so that it will not cause harm to the human body during use.
Turning the outer circular surface is the basic method of machining the outer circular surface in hardware processing, and the equipment used is a lathe. In general machinery factories, lathes account for about 40% of the total number of machine tools. Turning is the main method for roughing and semi-finishing the outer surface of various materials, and it is also the final finishing method for various materials that are not suitable for grinding.
When a single piece is produced in small batches, the turning of the outer surface is generally carried out on an ordinary lathe. In 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 are machined on heavy-duty horizontal lathes.
