Hardware parts processing method What are the common processing techniques of hardware parts processing?

2023-07-18

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

First, hardware parts processing two major methods:

Hardware processing methods do not have turning, milling, planing, grinding, tongs, stamping processing, casting and other methods.

1. Stamping processing: stamping selects pre-manufactured mold shells with a stamping machine to carry out cold stamping processing, the key to carry out Sheet Metal processing, that is, most of the processed material content is all furniture plates, the processing effect is very high suitable for mass production. And the processing technology is divided into engineering project mold and, continuous mold, engineering project mold is also called single cold stamping die, some more complex parts to use several sets of mold shells, and continuous mold in the injection mold of the die to split the appearance of the goods into multiple parts in a mold, so that the stamping machine processing a travel arrangement is a finished product. The fast continuous press can process three to four hundred goods per minute.

2. Lathe processing: Lathe belongs to high-precision processing machinery and equipment, which is divided into general lathes, automatic lathes, dashboard lathes and computer lathes. It carries out rotational fitness exercise according to the clamping of raw materials, and the cutting tool of the lathe carries out tangential or radial processing. Nowadays, the use of fully automatic lathes and computer lathes is becoming more and more common.

Since these two types of machining are all automatic, the precision deviation caused by the actual operation of human factors is reduced to the lowest point, and the processing speed is faster for mass production. Most of today's computer lathes are equipped with side rotating CNC inserts and reverse rotating CNC inserts, which means that cutting can also be carried out on lathes. The surface roughness of the machining surface of the lathe is about Ra0.4-1.6.

Hardware parts processing common four major processing technology:

1. Sheet metal processing

Sheet metal mold making is fast and cheap, and the delivery time is very short. Sheet metal can be a good alternative to injection-molded plastics for internal structural parts because it provides greater flexibility early in the design process, when the product may still change or the forecast of the product is unclear.

2. CNC Machining

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 approach the material.

3. Turning

Turning processes include cutting, face, threading, forming, drilling, knurling and boring. For the machining of the surface of hardware parts, turning is usually a good choice if you want to have a precision bearing surface in a complex machine.

4. EDM

Wire EDM is a high-precision technology that can cut almost any conductive material. A thin charged EDM wire mounted between two mechanical rails forms one electrode, and the material being cut forms the other. The discharge between the two electrodes (wire and workpiece) creates a spark that cuts the material. Since the live conductor never touches the workpiece in EDM machining, the process can be used to manufacture very small and precise parts that require a level of precision and complexity that cannot be achieved with traditional machining.
