Hardware surface processing subdivision can be divided into: metal painting processing, electroplating, surface polishing processing, metal corrosion processing, etc.
Hardware parts surface processing:
1, paint processing: hardware factory in the production of large pieces of metal products are used when the paint processing, through the paint processing to avoid rusting hardware, such as: daily necessities, electrical enclosures, handicrafts, etc.
2, electroplating: Electroplating is the most common metal processing of a processing technology, through the modern technology of the surface plating hardware to ensure that products do not occur under long-term use of mildew, embroidery, electroplating common: screws, stamping parts, Cell pieces, car parts, small jewelry, etc.,
3, the surface polishing: surface polishing generally used in daily necessities, through the surface of the metal products, such as burr processing: For example: we produce a comb, comb is made by pressing the hardware, then the punch out of the comb corner Is very sharp, we will have to polish the sharp part of the corner will be cast into a smooth face, so that in the course of the use will not cause harm to the human body.
Turning the outer surface of the metal processing is the basic method of processing the outer surface, the equipment used is a lathe. In the general machinery factory, lathes accounted for about 40% of the total number of machine tools. Turning is the main method of roughing and semi-finishing the outer surface of various materials, but also the final finishing method of various materials which should not be ground.
Single-piece small batch production, turning the general surface in the ordinary lathe. Large-scale production, the widespread use of multi-blade semi-automatic lathes or automatic lathes. Large-scale disk parts should be processed on a vertical lathe. Large long shafts are to be machined on heavy horizontal lathes.
Turning cylindrical surface features are:
1, the tool is simple, manufacturing, grinding and easy to install;
2, the cutting process is smooth, small fluctuations in cutting force, is conducive to the use of high cutting speed and improve productivity;
3, the machine is universal, and can be processed in a clamping in the cylindrical, face, bore, thread and chamfer. The accuracy of the mutual location between the surface is easy to guarantee;
4, suitable for non-ferrous metal parts of the finishing
