The most common product processing method in hardware processing plants

Generally, in hardware processing factories, most of the most common materials we use are stainless steel processing, copper processing, aluminum processing and iron processing. Then the hardware processing factory processes various precision parts according to the customer's drawings or samples through lathe processing, milling machine processing, grinding machine processing and polishing, commonly known as hardware precision parts processing, like those screws, axle shafts, car parts models, mobile power housing, cnc housing, etc. are processed by hardware precision parts. Let's talk about polishing, oxidation, passivation, machining, rolling, tapping and electroplating of the most common hardware products. 1. The principle of polishing and polishing refers to making the product bright and smooth through regular dissolution. Use of polishing: using mechanical, chemical or electrochemical functions to reduce the surface roughness of the workpiece to obtain a bright and smooth surface processing method, it is a modification of 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-casting aluminum oxidation, color oxidation, aluminum anodized, natural color oxidation, etc. 3. The principle of passivation and Passivation can be explained by film theory. Passivation is due to the action of metal and oxidizing substances, when acting, a very thin, dense, well-covered, firmly adsorbed passivation film on the metal surface is formed on the metal surface. Compared with the traditional physical sealing method, the passivation treatment has the characteristics of absolutely not increasing the thickness of the workpiece and changing the color, improving the precision and added value of the product, and making the operation more convenient; 4. Machining is commonly used in turning, planing, milling and grinding. 5. Rolling teeth are used to squeeze the machined workpiece with two threaded sticks so that the surface of the part is pressed out of the thread. 6. Tapping teeth is a die, which is used to process or repair external threads. Its interior is threaded and can be manually processed or used on a threading machine. 7. Electroplating and electroplating are divided into hanging plating, rolling plating, continuous plating and brush plating, which are mainly related to the size and batch of parts to be plated.
