The most common processing method for precision parts processing

In general precision parts processing , most of the most common incoming materials processing materials we see are stainless steel material processing, copper material processing, aluminum material processing, and iron material processing. Then the precision parts processing factory then processed into various precision parts according to the customer's drawings or samples through lathe processing, milling machine processing, grinding machine processing and polishing machinery, commonly known as hardware precision parts processing, such as screws, motor shafts, car parts models, Mobile power housing, CNC housing, etc. are processed by hardware precision parts.

Let’s talk about the most common precision parts processing, polishing, oxidation, passivation, machining, tooth rolling, tapping, and electroplating.

1. Polishing

The polishing principle refers to making the product bright and smooth through regular dissolution.

How to use polishing: The processing method of using mechanical, chemical or electrochemical effects to reduce the roughness of the workpiece surface to obtain a bright and flat surface is to modify the surface of the workpiece using polishing tools and abrasive particles or other polishing media. .

2. Oxidation

Oxidation is divided into aluminum hard oxidation, die-cast aluminum oxidation, color oxidation, aluminum anodization, natural oxidation, etc.

3. Passivation

The passivation principle can be explained by the film theory. Passivation is caused by the action of metal and oxidizing substances. When it is applied, it generates a very thin, dense, good coverage and firmly adsorbed on the metal surface. Modification film. Compared with the traditional physical closure method, the passivation process has the characteristics of absolutely no increase in the thickness of the workpiece and changing the color, which improves the precision and added value of the product, making the operation more convenient;

4. Commonly used machining include turning, planing, milling, and grinding.

5. Tooth rolling

Rolling is the use of two threaded sticks to squeeze the workpiece to be processed so that the surface of the part is pressed out of the thread.

6. Tapping

Tapping is a plate tooth, which is used to process or repair external threads. It has threads inside and can be processed manually or used on a wire stitching machine.

7. Electroplating

Electroplating is divided into hanging plating, boiling plating, continuous plating and brush plating, which are mainly related to the size and batch volume of the parts to be plated.
