The development of many industries in life is inseparable from aluminum alloy flange manufacturers. Sometimes some inconspicuous factors may cause a big gap, such as the aluminum alloy parts processing mentioned before. Today we will come to understand Let’s talk about “Precautions on the processing of mechanical parts in Shenzhen How to deal with the surface roughness of mechanical parts”.
The main features of Shenzhen machining: invisible leakage, friction reduction, power loss, shaft or sleeve without any wear, flexibility to adapt to shaft deflection, indefinite maintenance, and longevity.
The product details of composite fiber mechanical seal processing parts are packaged with the low pressure cover tightening to provide composite fiber packaging with a low pressure cover tightening. The composite fiber mechanical seal processing parts are manufactured with low pressure cover and fastened packaging to provide all the advantages of aramid fiber, excellent lubricity, and stable temperature. The composite fiber packaging gland has low tightness and can provide a good seal. Its model name is 4000 Macstar. The low-pressure cover is made of composite fiber for fastening packaging, and the mechanical seal processing parts have high-strength aramid 49 combination. This thirsty fiber picks up @ 70% PTFE, so it becomes very dense and requires very low gland tightening.

The most commonly used forms of valves for machining parts are wedge gate valves and parallel gate valves. The stem axis of the globe valve is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action, making this valve very suitable for the cut-off or adjustment and throttling of the medium. The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. Since the program is also executed from this point, the tool setting point is also called the program starting point or starting point. When the machining accuracy requirements are not high, you can directly use some surfaces on the workpiece or the fixture as the tool setting surface; when the computer gong processing accuracy is high, the tool setting point should be selected as far as possible on the design datum or process datum of the part, such as For parts with hole positioning, it is more appropriate to take the axis of the hole in the machining of mechanical parts as the tool setting point. The tool setting point must have a certain coordinate relationship with the positioning datum of the workpiece, and the computer gong processing can determine the relationship between the machine tool standard system and the workpiece coordinate system. The selection of tool setting points for computer gong processing should facilitate the calculation of coordinate values and make tool setting convenient. When setting the tool, the tool setting point should coincide with the tool position point. The so-called tool position point in the mold factory refers to the intersection of the tool axis and the bottom surface of the tool for flat-bottomed end mills; for ball end mills, it refers to the center of the ball part; for turning tools, it refers to the tip of the tool; for drills, it refers to the point of drill. ; For the wire electrode cutting machine in Shenzhen, the precautions for the processing of mechanical parts in Shenzhen refer to the focus of the wire electrode axis and the part surface.
The surface roughness of auto parts is an important technical indicator reflecting the microscopic geometric shape error of the part surface, and the main basis for testing the surface quality of the parts; whether it is selected reasonably or not is directly related to the quality, service life and production cost of the product. There are three methods for selecting surface roughness of mechanical parts, namely calculation method, test method and analogy method. In the design of mechanical parts, the most common application is the analogy method, which is simple, fast and effective. The application of analogy requires sufficient reference materials, and various existing mechanical design manuals provide more comprehensive materials and documents. The most commonly used is the surface roughness that is compatible with the tolerance level. Under normal circumstances, the smaller the dimensional tolerance requirements of mechanical parts, the smaller the surface roughness value of mechanical parts, but there is no fixed functional relationship between them. For example, the handles on some machines, instruments, handwheels, and sanitary equipment, food machinery, the modified surface of certain mechanical parts, their surface requirements are very smooth, that is, the surface roughness requirements are very high, but their dimensional tolerances are very demanding. Low. Under normal circumstances, there is a certain correspondence between the tolerance level and the surface roughness value of the parts with dimensional tolerance requirements.
The above is a brief introduction about “precautions for processing mechanical parts in Shenzhen, how to deal with the surface roughness of mechanical parts”, our company also has aluminum alloy flange manufacturers, Aluminum alloy flange manufacturers and many other related products, if you are more interested, you can contact us for more detailed information.
