What are the requirements for raw materials for hardware parts processing?

CNC hardware parts processing, not any data can be processed finely. Some data is too hard, exceeding the hardness of the processed parts, and may crash the parts, so these data are not suitable for fine processing unless it is cut by special data parts, or laser.

Finishing data is divided into metal data and non-metal data.

For metal data, the hardness of stainless steel is followed by cast iron, followed by copper, and then aluminum.

The processing of ceramics, plastics, etc. is the processing of non-metal data.

1. The first is the requirement of data hardness. In some cases, the higher the hardness of the data, the better. Hardness requirements for machining parts. If the processing data is harder than the parts, it cannot be processed.

Second, the raw materials have moderate softness and hardness, at least one level lower than the hardness of the parts. At the same time, this depends on the function of the processing equipment and the material of the parts is reasonably selected.

Generally speaking, finishing still has some requirements for raw materials, and not all raw materials are suitable for processing. For example, the data is too soft or too hard. The former does not require processing, while the latter cannot be processed.

Therefore, the density of raw materials must be paid attention to before processing. If the density of the fruit is too high, the hardness is also very high. If the hardness exceeds the hardness of the part (turning tool) and cannot be processed, it will not only damage the parts, but also cause risks, such as the collapse of the turning tool. Therefore, generally speaking, for mechanical processing, the data raw material should be lower than the hardness of the tool.

Common appearance treatment of CNC-processed hardware.

The hardware appearance processing subdivision can be divided into: hardware oxidation processing subdivision, hardware painting processing, electroplating, polishing processing, metal corrosion processing, etc.

Hardware surface processing:

1. Oxidation processing: Hardware factories perform oxidation processing when producing finished hardware products (mainly aluminum), making the surface of the hardware products hard and not easily wear.

2. Painting processing: The hardware factory uses spraying processing when producing large hardware products to prevent the hardware from rusting after spraying, such as daily necessities, electrical shells, handicrafts, etc.

3. Electroplating: Electroplating is also a common processing technology in hardware processing. The appearance of hardware is electroplating through modern technology to ensure that the product is free of mold and embroidery after long-term use. Common electroplating processing include: screws, stamping parts, batteries, auto parts, small accessories, etc.

4. Appearance polishing treatment: Appearance polishing treatment is generally used for daily necessities. After the appearance of the hardware product burr: The combs we produce are stamping hardware, so the stamping comb angle is very sharp. During use, we lubricate the face of the pointed corners and will not cause harm to the human body.
