1. ABS plastic ABS resin is one of the five major anti-corrosion coatings. Its impact resistance, temperature resistance, low temperature resistance, chemical resistance and electrical equipment performance are high. It also has the characteristics of easy production and processing, stable product specifications, and good surface gloss. , It is very easy to spray and color, and it can also carry out secondary production and processing such as surface metal plating, electroplating process, electric welding, pressing and bonding, and is widely used in mechanical equipment, vehicles, electronic materials, instrumentation equipment, textile industry It is a thermosetting rubber product with a wide range of main uses. ABS is usually a pale yellow or white powder amorphous epoxy resin. ABS is one of the most commonly used rubber products.

1. Geometric shape accuracy: The geometric shape accuracy (cylindricity, coaxiality) of the journal should generally be limited to the diameter dimensional tolerance point. When the precision of the graphic appearance is higher, the allowable dimensional tolerance can be specified on the high-precision part drawing. 2. Surface roughness: The editor of precision parts processing tells you that there are different surface roughness values according to the different positions of the surface of the high-precision parts. For example, the surface roughness of the spindle bearing journal of a general lathe is Ra0. 160.63um, the surface roughness of the mutual matching journal is Ra0.632.5um. With the expansion of equipment operation speed and the improvement of high precision level, the surface roughness value of high precision parts of shaft parts will also become smaller and smaller. .

Communication should be emphasized in the production process of high-precision parts. No matter whether there is a problem at the connection point, communication needs to be strengthened. Communication between processing plants and machine equipment manufacturers is the main standard for processing automated machine parts. The processing staff usually carry out the processing work according to the design drawings, but a lot of time, many technological processes can be simplified and improved, which can control the cost and improve the output power.

Decryption of aluminum alloy precision parts processing technology

2022-05-09

Aluminum alloy precision parts processing technology is a comprehensive system engineering, which comprehensively uses CNC lathes, special tools, metrology verification, environmental technology, electronic information technology, computer technology, CNC machining technology, etc., to further improve the high precision of aluminum alloys. The machining accuracy of the parts must be further scientifically researched. With the rapid development of the manufacturing industry and the development of management science, the demand for the machining precision of aluminum alloy precision parts in each field is getting higher and higher. In addition to the machining accuracy, better regulations are also clearly put forward for the surface of aluminum alloy high-precision parts - surface consistency. With the development trend of science and technology, the machining precision, difficulty factor and diversity of aluminum alloy precision parts are gradually improving.

What is the benchmark of precision parts processing technology

2022-05-09

Precision parts processing technology benchmarks can be divided into different processes: casting, forging, stamping, welding, heat treatment, machining, and installation. The processing process of precision parts generally refers to the general term for the CNC lathe processing and equipment installation process of all parts, while the rest such as cleaning, testing, equipment maintenance management, and sealing rings are just assistance processes. The method of milling changes the surface properties of raw materials or semi-finished products. This process is called CNC lathe machining process. In the field of precision parts processing, CNC lathe machining process is the most critical process.
