Hardware Surface Processing

Hardware Surface Processing:

1. Painting: Hardware factories often use painting when producing large hardware products. This process prevents rust on finished hardware, such as everyday items, appliance housings, and handicrafts.

2. Electroplating: Electroplating is also a common process in hardware processing. Using modern technology, the surface of hardware parts is plated to prevent mold and rust from forming over time. Common applications of electroplating include screws, stamped parts, battery cells, auto parts, and small accessories.

3. Surface Polishing: Surface polishing is commonly used on everyday items to remove burrs from the surface of hardware products. For example, if we produce a comb, which is a stamped hardware component, the edges are very sharp. Polishing these edges to a smooth surface prevents them from causing any damage during use.

External cylindrical turning is a basic method of external cylindrical surface machining in hardware processing, and the equipment used is a lathe. In general machinery plants, lathes account for approximately 40% of the total machine tool fleet. Turning is the primary method for roughing and semi-finishing the external surfaces of various materials, and it also serves as the final finishing method for materials that are not suitable for grinding.

For single-piece, small-batch production, external surface turning is generally performed on conventional lathes. For large-scale production, multi-tool semi-automatic or automatic lathes are widely used. Large disc-like parts should be machined on vertical lathes. Large, long shaft-like parts require heavy-duty horizontal lathes.
