Surface polishing of the surface processing of CNC parts: Surface polishing is generally used in daily necessities, through the surface burr treatment of hardware products. For example, we produce a comb. The comb is a hardware part made by stamping, then it is stamped out. The corners of the comb are very sharp. We need to polish the sharp corners into a smooth face so that it will not cause harm to the human body during use.
Spray paint processing: The hardware factory uses spray paint processing when producing large hardware products, and the metal parts are protected from rust through spray paint processing, such as daily necessities, electrical enclosures, handicrafts, etc.
Electroplating: Electroplating is also one of the most common processing techniques for hardware processing. The surface of hardware is electroplated through modern technology to ensure that the product will not be moldy or embroidered under long-term use. Common electroplating processing includes screws, stamping parts, and battery chips. , Car parts, small accessories, etc.
Turning the external surface is the basic method of external surface processing in the surface processing of hardware parts, 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 rough machining and semi-finishing of the outer surface of various materials, and it is also the final finishing method for various materials that are not suitable for grinding.
When producing a single piece in small batches, turning the outer surface is generally performed on a normal lathe. In mass production, multi-tool semi-automatic lathes or automatic lathes are widely used. Large disc parts should be processed on a vertical lathe. Large long shaft parts need to be processed on a heavy-duty horizontal lathe.
