The processing methods of hardware accessories include turning, milling, planing, grinding, tongs, stamping, and casting.

Stamping: Stamping uses pre-made molds for cold stamping processing, mainly for sheet metal processing, that is, most of the processed materials are sheet materials, and the processing efficiency is relatively high and suitable for mass production.

The processing technology is divided into engineering molds and continuous molds. Engineering molds are also called single-punch dies. Some more complex parts require several sets of molds. The continuous mold is in the cavity of the mold to split the shape of the product into several parts. In a mold, one stroke processed by such a punch is a finished product. The high-speed continuous punching machine can process three to four hundred products per minute.

Lathe: Lathe is a precision processing machine, divided into ordinary lathe, automatic lathe, instrument lathe and computer lathe. It uses the turning tool to perform radial or axial machining by clamping the material and then rotating it.

Nowadays, automatic lathes and computer lathes are more and more widely used. Because these two are fully automatic processing, the accuracy error caused by human operation is reduced to the lowest point, and the processing speed is fast, which is used for mass production. Most of the current computerized lathes are equipped with side-rotating tools and back-rotating tools, which means that the lathe can also be milled. The surface roughness of the lathe is about Ra0.4-1.6;
