At present, there are more than ten categories of metal products actually operated in the material market, and hundreds of products. For example: raw materials such as stainless steel, copper, aluminum, iron, iron, aluminum alloy, etc. are then processed by lathes and milling machines to process customer drawings or samples, drilling machines, polishing machines, etc. to become various ideal parts. What are the processing methods of hardware parts?

1. Two major methods of processing hardware parts:

Metal processing methods include turning, milling, planing, grinding, clamping, stamping, casting and other methods.

1. Stamping processing: stamping uses pre-made mold shells to carry out cold stamping processing with a stamping machine, mainly Sheet Metal processing, that is, most of the processed materials are furniture plates, and the processing effect is very high and suitable for mass production. The processing technology is divided into engineering molds and continuous molds. Engineering molds are also called single-cold dies. Some more complex parts need several sets of molds, and the continuous mold separates the appearance of the product from the concave mold of the injection mold. Several parts are in one mold, so that one stroke processed by the stamping machine is a finished product. The fast continuous stamping machine can process three or four hundred products per minute.

2. Lathe processing: Lathes belong to high-precision processing machinery and equipment, which are divided into general lathes, automatic lathes, instrument panel lathes and computer lathes. It performs rotational movement by clamping the material, and performs tangential or radial processing by the lathe tool. Nowadays, the use of fully automatic lathes and computer lathes is becoming more and more common.
Because these two types are all automatic processing, the accuracy deviation caused by human operation is minimized, and the processing speed is faster, which is suitable for mass production. Most of today's computerized lathes are equipped with side-rotating CNC inserts and reverse-rotating CNC inserts, which means that cutting can also be performed on the lathe. The surface roughness of lathe processing surface is about Ra0.4-1.6
2. Four common processing techniques for hardware parts processing:
1. Sheet metal processing
Sheet metal tooling is quick and cheap to make, with very short lead times. Sheet metal can be a good alternative to injection molded plastic for internal structural components, as it provides greater flexibility in the early stages of the design process, when the product may still be subject to change or the forecast for the product is unclear.

2. Cnc Machining Parts
CNC is a cost-effective solution for machining parts with complex shapes and tight tolerances. CNC precision machining can machine almost any shape, as long as the rotating cutting tool can get close to the material.
3. CNC turning service
Turning processes include cutting, facing, threading, forming, drilling, knurling and boring. Turning is often a good choice for machining the surface of metal parts if you want to have a precision bearing surface in a complex machine.
4. EDM
Wire-cut electrical discharge machining (EDM) is a high-precision technique that can cut virtually any conductive material. A thin live EDM wire mounted between two mechanical rails forms one electrode, while the material being cut forms the other electrode. An electrical discharge between two electrodes (lead and workpiece) creates a spark that cuts the material. Because live wires never touch the workpiece during EDM machining, the process can be used to create very small and delicate parts that require a level of precision and complexity that cannot be achieved with traditional machining.
