As we all know, rare earth has always been China's national defense strategic armament material. At the same time, due to its irreplaceable role in national defense and military weapons and equipment, and its reserves are extremely low, all countries are making long-term reserves. At present, the advanced weapons and equipment of western countries are extremely dependent on China's rare earth materials. The United States, in particular, relies almost entirely on imports from China. Of course, in addition to the military field, these materials are also used in smart phones, global positioning systems, automotive electronic components, computers, computer screens and…

Tool steel is particularly attractive to manufacturers compared to steel. As its name suggests, tool steel is very suitable for making tools. It is a very hard, highly heat-resistant and wear-resistant material, with multiple grades, suitable for various applications. For such a high-quality material, the 3D printing industry certainly has a great demand, as CEO markforge pointed out in a recent interview. Markforge will develop tool steel materials for its metal x 3D printer. It is exciting that nanosteel has taken the lead. Today, the company announced the launch of a new 3D printing tool steel material, which is also…

Lithium batteries are widely used in mobile devices such as mobile phones and laptops. Dangerous events such as ignition of mobile devices due to battery short circuit are also increasing. Scientists from China and the United States have jointly completed a new study. They have added nano-sized diamond particles to the electrolyte of lithium batteries to prevent the formation of deposits inside the batteries that lead to short circuits and avoid fire accidents caused by battery short circuits. Lithium battery has high energy density and good discharge performance, and is widely used in industry and consumer electronics. However, if pure…

Mechanical drawings are the summary of technical requirements and the necessary data for robots. Remember to collect them! ▌ general technical requirements 1. Remove scale from parts. 2. The processing surface of the parts shall be free from scratches, scratches and other defects that damage the surface of the parts. 3. Remove burrs and flash. ▌ heat treatment requirements 1. HRC50 ～ 55 after quenching and tempering. 2. Parts shall be subject to high-frequency quenching, tempering at 350-370 ℃, and hrc40-45. 3. Carburizing depth: 0.3mm. 4. Conduct high temperature aging treatment. ▌ tolerance requirements 1. The unspecified shape tolerance shall…

1、 What is non-standard mechanical design? In short, it is the design of non-standard equipment, non-standard parts and non-standard tooling. For example: C616, C620, C630, c6125, M7475, b650, M131 and other equipment are well-known standard equipment in the machining industry, so there are many special equipment not included in the standard equipment, which is the work goal of non-standard designers. Non standard machinery is a mechanical product that is not finalized. Generally, it can not be bought directly in the market. It should be customized from the manufacturer. The size and shape of machines with the same function may be…

The process of the birth of an innovative product from birth to birth should be like this: a little adorable idea, and then let a designer to discover the shape you give the product. Next, let the product upgrade in dimension -- from the two-dimensional of the drawing to the three-dimensional of the hand plate, then adjust the idea; Then, adjust the design; Then, adjust the material; Then, adjust the process. Finally, the goddess in my mind appeared, so, mold opening, production, marketing It can be seen that in the whole process, the link around the hand board is the…

"CNC" refers to the numerical control technology of computerized numerical control (numerical control for short). Traditional machining is operated by hand with ordinary machine tools. When machining, shake the mechanical tool by hand to cut metal, and measure the accuracy of products with caliper and other tools by eyes. Modern industry has long used computer digitally controlled machine tools for operation. CNC machine tools can automatically process any products and parts directly according to the program compiled by technicians in advance. It is a method of using digital information to control the movement and machining process of machine tools. The…

7、 Semi solid metal forming Semi solid forming: the unique rheological and stirring properties of non dendritic semi-solid metals (SSM) are used to control the quality of castings. Semi solid forming can be divided into rheological forming and thixotropic forming.  (1) Rheoforming (2) Thixoforming Technical features: 1. Reduce liquid forming defects and significantly improve quality and reliability; 2. The forming temperature is lower than the full liquid forming temperature, which greatly reduces the thermal shock to the mold; 3. It can produce alloys that cannot be produced by conventional liquid forming methods; Application: at present, it has been successfully used…

6、 Metal injection molding MIM (metal injection molding): short for metal injection molding. It is a forming method of injecting the plasticized mixture of metal powder and its binder into the model. Firstly, the selected powder is mixed with the binder, then the mixture is granulated, and then the shape required by injection molding is formed. MIM process flow: MIM process is divided into four unique processing steps (mixing, forming, degreasing and sintering) to realize the production of parts, and determine whether surface treatment is required according to the product characteristics. Technical features: 1. Responsible for the parts of one-time…

5、 Powder metallurgy Powder metallurgy: it refers to the process technology of making metal or using metal powder (or the mixture of metal powder and non-metallic powder) as raw material, forming and sintering, and manufacturing metal materials, composite materials and various types of products. Basic process flow: Process advantages: 1. Most refractory metals and their compounds, pseudoalloys and porous materials can only be manufactured by powder metallurgy. 2. Save metal and reduce product cost. 3. It will not pollute the materials, and it is possible to produce high-purity materials. 4. Powder metallurgy can ensure the correctness and uniformity of material…
