In the CNC cutting process, there are many reasons for machining errors. The error caused by the tool radial runout is one of the important factors, which directly affects the minimum shape error and the machined surface geometry accuracy. In actual cutting, the radial runout of the tool affects the machining accuracy, surface roughness, uneven wear of the tool, and the cutting process characteristics of the multi-tooth tool. The greater the radial runout of the tool, the more unstable the machining state of the tool, and the more obvious the impact. Causes of radial runout Tool manufacturing errors and clamping errors cause drift and eccentricity between the tool axis and the ideal rotation axis of the spindle, as well as specific processing techniques and tooling, which may cause radial runout of CNC milling machine tools during processing. The influence of the radial runout of the spindle itself The main reasons for the radial runout error of the main shaft are the coaxiality error of each journal of the main shaft, various errors of the bearing itself, the coaxiality error between the bearings, and the deflection of the main shaft. Their influence on the radial rotation accuracy of the spindle varies with the processing method. These factors are formed in the process of manufacturing and assembling the machine tool, and it is difficult for the operator of the machine tool to avoid their influence. The impact of the inconsistency between the tool center and the spindle rotation center When the tool is installed on

Detailed advantages and disadvantages of 3D printing Detailed advantages of 3D printing Reduce the complexity of product manufacturing Unlike traditional manufacturing that uses molds, turning and milling and other mechanical processing methods to shape and cut raw materials to finally produce products, 3D printing converts three-dimensional entities into several two-dimensional planes, and produces by processing materials and superimposing them layer by layer. , Which greatly reduces the complexity of manufacturing. Expand the scope of manufacturing This digital manufacturing mode does not require complicated processes, large machine tools, or a lot of manpower. Parts of any shape can be generated directly from computer graphics data, so that manufacturing can be extended to a wider range and any shape can be manufactured. Shorten manufacturing time and improve efficiency It usually takes several hours to several days to manufacture a model by traditional methods, depends on the size and complexity of the model, while the use of 3D printing technology can shorten the time to several hours. Of course, this is also determined by the performance of the printer and the model, also it depends on size and complexity. Reduce the process of product manufacturing The net shape forming of the first piece is practiced, so that the amount of auxiliary processing in the later stage is greatly reduced, and the data leakage and time span of outsourcing processing are avoided. It is especially suitable for some high confidentiality industries, such as military industry and nuclear power. Promptproduction andmeet the individual needs of customers

3D Printing 3D printing is a kind of rapid prototyping technology. It is a technology that builds objects based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer. 3D printing is usually done by using digital technology data printers. It is often used to make models in the fields of mold making and industrial design, and then gradually used in the direct production of some products. The technology is used in jewelry, footwear, industrial design, construction, engineering and construction, cars, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns, and other fields. How does 3D printing create value and profit There are many companies in the world that do 3D printing processing services, but few can rely on it to make money in China. On the one hand, because China’s traditional manufacturing industry is too mature and developed, the products produced by the new manufacturing method of 3D printing are temporarily not competitive with products produced by traditional technologies in terms of product performance and processing costs. On the other hand, although there are many practitioners in the 3D printing industry, there are very few people who can really play the potential of this technology’s huge added value. At present, only some giant companies in the world that have invested a lot in 3D printing technology research and development can create value through 3D printing, such as GE, Siemens, Airbus, BMW, Johnson and so on. The product value of these

In modern industrial manufacturing, the scope of application of CNC Machining is undoubtedly very huge, and it has its irreplaceable role and advantages in manufacturing. In recent years, with the development of 3D technology, 3D printing has also begun to penetrate into various production and manufacturing, and the advantages of 3D printing have continued to be reflected. It is necessary for us to understand the advantages and disadvantages of 3D printing, so as to better organize production and manufacturing, so that their respective advantages can be brought into play. 3D printer, also known as three-dimensional printer (3DP), is a kind of cumulative manufacturing technology, that is, a kind of machine of rapid prototyping technology. It is based on a digital model file and can be bonded with special wax materials, powdered metals or plastics. Materials, by printing layers of adhesive materials to create three-dimensional objects. At this stage, 3D printers are used to manufacture products. The technique of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. The advantages of using 3D printer model production are obviously increased. Compared with the traditional manufacturing steps, the advantages are as follows: There is no additional cost for making chaotic objects. As far as traditional manufacturing is concerned, the more chaotic the style of the object, the higher the manufacturing cost. For 3D printers,

We are working our best work for your custom plastic & metal machining parts from design drawing or sample to final shipment with fast delivery and low MOQ. We are using advanced technology and equipment to offer high precision for producing metal and plastic machining parts. In this article, We introduce eight categories of injection molds. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic part, which is called a single parting surface mold, also called a double-plate mold. It is the simplest and most basic form of injection mold. It can be designed as a single-cavity injection mold or a multi-cavity injection mold according to needs. It is the most widely used injection mold. Double parting surface injection mold The double parting surface injection mold has two parting surfaces. Compared with the single parting surface injection mold, the double parting surface injection mold adds an intermediate plate (also called movable gate plate, It is equipped with gates, runners and other parts and components required by the fixed mold), so it is also called a three-plate (moving plate, intermediate plate, fixed plate) injection mold, which is often used for single-type point gate feeding For injection molds with multiple cavities or multiple cavities, when the mold is opened, the intermediate plate is separated from the fixed template at a fixed

Can titanium be CNC machined? At present, many Machininery manufacturers have launched high-efficiency high-speed CNC machine tools for HEM-HSM cutting of large aluminum alloys CNC Machining and other light alloy materials. It is obviously inappropriate to realize HEM-HSM machining with difficulty to machine metal materials with high strength and high hardness like Titanium. Although it can also cut these hard alloy materials, its cutting efficiency is often unacceptable. The main reasons are: (1) As mentioned above, the machining of hard alloy materials such as titanium alloys requires large cutting force, or high torque spindles, and high-efficiency high-speed CNC machine tool spindles are typically used for HEM-HSM cutting of light alloy materials such as aluminum alloys. Most of the torque is less than 100Nm, generally not more than 200Nm, and it does not have the cutting ability for high-efficiency machining of hard alloy materials such as titanium alloys. (2) As mentioned above, the processing of titanium alloys and other hard alloy materials is usually only allowed to use lower cutting speeds, that is, only lower spindle speeds can be used, and the HEM-HSM cutting processing of light alloy materials such as aluminum alloys is typically used. The spindle speed range of high-efficiency high-speed CNC machine tools is not compatible with the requirements of the current titanium alloy processing technology. Therefore, it needs to special design and manufacture of many key CNC components such as the structure, rigidity, dynamic characteristics, spindle and coordinate drive, cooling system, tool interface, and control system of

We are working our best work for your custom plastic & metal machining parts from design drawing or sample to final shipment with fast delivery and low MOQ. We are using advanced technology and equipment to offer high precision for producing metal and plastic machining parts. In this article, we focus on some common problems and solutions of aluminum alloy parts processed by CNC wire cutting. When machining aluminum alloy parts by CNC wire cutting, there are often problems such as serious wear of the feed block, short circuit, wire breakage, processing track distortion, and workpiece deformation, and some directly cause the processed product to be scrapped.  The problem of wire-cutting aluminum alloy parts easy to break The reason why wire-cut aluminum alloy parts are easy to break When wire cutting aluminum alloy parts, because the material is relatively soft, chip removal is difficult, and aluminum alloy is very easy to form a hard oxide film at high temperatures. A large amount of aluminum oxide or aluminum scraps is easy to stick to the molybdenum wire, making the molybdenum wire and the feed block Deep grooves will soon be ground at the contact area. Soft aluminum and hard abrasive grains are mixed together and stuffed in the groove. Once brought in, the groove will be squeezed to death, and the wire will be jammed. Solution In view of the problem that the molybdenum wire is caught in the feed block and the molybdenum wire is
