Compared with the development level of foreign 3D printing technology, there is still a certain gap in our country, but don’t be discouraged, we also have our strengths and advantages in this industry. The research on china 3D printing technology started as early as the early 1990s. System of Chinese Academy of Sciences. At present, these universities are still the research centers of 3D printing technology in my country. Among them, Huazhong University of Science and Technology has the advantage of laser powder unsintering technology, Tsinghua University focuses on plastic accumulation technology and biomedical fields, Beihang University and Northwestern Polytechnical University mainly focus on In the field of metal Jinan 3D printers, Xi’an Jiaotong University mainly focuses on the field of photocuring in the whole field of 3D printing, and the development at home and abroad is also similar. In terms of equipment production, the functions of 3D printer equipment Read more

As the world’s factory, China naturally has advantages that other countries do not have, such as domestic 3D metal printing technology, so how good is China 3D printing Service? Its importance is not lost to the lithography machine. The United States has requested three times but was rejected? It turns out that China’s 3D metal printing technology leads the world, and its importance is not lost to the lithography machine. No wonder foreign countries can’t buy it with a lot of money. It is useful to circle it. 3D metal printing is a basic discipline used in physics, engineering and technical science , Scientific instruments in the field of mechanical engineering. In the field of mechanical processing, China started relatively late. In the industry, there is a term called standardization, that is, the components of industrial products are produced by the same process, which requires the use of machine tool Read more

One weekend morning, a small 3D printing technology demonstration was being held in a cafe where entrepreneurs gathered in Haidian District, Beijing. The organizer is Tiertime Technology Co., Ltd., the largest portable 3D printer manufacturer and 3d printing China. This time they brought 8 desktop 3D printers with a height of only 13 cm. This event attracted many technology enthusiasts and technology enthusiasts. Many people brought their own 3D works, hoping to “print” these works with 3D printers. The printing process is very simple. The experiencer only needs to connect the printer to his own laptop through the USB interface, download the drawing software from the official website of Tyre, and import the 3D graphics file on the drawing platform; then start the printer, and the “ink” – ABS will be printed. After the plastic coil is installed on the printer, the computer will automatically import the 3D data into Read more

In the design process of aluminum alloy die castings, many customers are uncertain about the thickness of aluminum alloy die castings, and they do not know how thin the thickness of aluminum alloy die castings can be.

According to the introduction of precision CNC machining manufacturers, the large-scale CNC machining parts are made of bar materials, and the process plan of rough machining and finishing is adopted. The specific process flow is as follows: blank → rough turning → rough milling → aging → fine turning → fine milling.

Modify tool offset value to ensure dimensional accuracy According to stainless steel parts machining manufacturers, when the workpiece error exceeds the workpiece tolerance due to the first tool setting error or other reasons, and the processing requirements cannot be met, the workpiece can be modified to achieve the required size by modifying the tool compensation. The method to ensure the radial size is as follows: Absolute coordinate input method According to the principle of “large reduction, small increase”, modify the tool compensation at 001～004. If the workpiece size is larger by 0.1mm when cutting the groove with the No. 2 cutting tool, and the tool compensation display at 002 is X3.8, you can enter X3.7 to reduce the No. 2 tool compensation. Relative coordinate method As in the above example, input U-0.1 at 002 cutter compensation, and the same effect can also be obtained. The same is true for the Read more

Aluminum is the most widely used and widely used metal material among non-ferrous metals, and its application range is still expanding. There are many kinds of aluminum products produced using aluminum, and there are more than 700,000 types according to statistics. Various industries such as construction and decoration, transportation, and aerospace have different needs. Today I will introduce to you the processing technology of stand casting and how to avoid processing deformation.
