High speed die cutting

With the increasing aesthetic and functional requirements of the product, the internal structure of the product is designed more and more complex, and the shape design of the mold is more and more complex. The proportion of free surface is increasing, and the corresponding mold structure is more and more complex. All of these put forward higher requirements for mold processing technology. High speed machining technology has been increasingly used in mold cavity processing and manufacturing. Compared with the traditional cutting, the cutting speed and feed speed of CNC high speed cutting have been greatly improved, and the cutting mechanism…

What are the common tools in CNC machining of hand model?

The selection of the hand model cutter is one of the important contents in the NC machining process, which not only affects the machining efficiency of the machine tool, but also directly affects the machining quality of the parts. NC tool is one of the prerequisites to improve the processing efficiency. Its selection depends on the geometric shape of the part to be processed, the material state, and the rigidity of the tool selected by the fixture and machine tool. Different tools have different uses in the NC machining process, so what tools are commonly used in the NC machining…

Stamping process

What is stamping? Stamping is a forming processing method of workpieces (stamping parts) with required shape and size by applying external force on plates, strips, pipes and profiles by press and die to cause plastic deformation or separation. The car body, chassis, fuel tank, radiator sheet, boiler drum, container shell, motor, electrical iron core silicon steel sheet, etc. are all processed by stamping. Instruments, household appliances, bicycles, office machinery, household utensils and other products also have a large number of stamping parts. According to the stamping processing temperature, it can be divided into hot stamping and cold stamping. The former is suitable…

CNC high gloss processing technology

At present, CNC high finish machining process (milling, turning) is not well known by technicians in most industrial industries. The actual work shows that they are really controlled by only a few production enterprises. The main reason is that the demand is not very strong in the past, which is also closely related to cognitionIn recent years, with the development of high-performance and high-precision CNC machine tools and the emergence of high-performance metal cutting tools, CNC high finish machining has made a great breakthrough. It is possible to replace grinding with milling (turning), which has become the goal pursued by…

Basic knowledge of industrial prototype

One What is a blackboard? In the process of product design, after we have completed the design drawings, one of the most important things we want to do is to know what kind of things we design are made into real objects, whether the appearance is consistent with our own design ideas, whether the structural design is reasonable, and so on. Prototype manufacturing is the product of this demand. Generally speaking, a prototype is one or several templates made according to the product appearance and structure drawings to check the appearance or structure rationality and function without mold opening. On the…

Analysis of hot stamping technology

Generally, hot stamping is to heat the steel plate to about 900 ℃ austenite before stamping, and then cool the parts by rapidly injecting water into the stamping die. Through this thermal cycle and cooling process, the strength of the steel plate can be greatly improved, and the tensile strength can be increased from about 500MPA under delivery to about 1500MPa after hot stamping. According to different processes, hot stamping can be divided into direct hot stamping and indirect hot stamping. 01 Direct Hot Stamping Technology After blanking, the hot formed steel plate is directly heated to the austenitizing temperature without…

Vacuum heat treatment technology

Vacuum heat treatment technology mainly refers to a new type of heat treatment technology combining vacuum technology and heat treatment technology. The vacuum environment in which vacuum heat treatment is located refers to an atmosphere environment lower than one atmospheric pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum. Therefore, vacuum heat treatment actually belongs to atmosphere controlled heat treatment. Vacuum heat treatment refers to that all or part of the heat treatment process is carried out under vacuum. Vacuum heat treatment can realize almost all the heat treatment processes that can be involved in conventional heat treatment,…

Experience summary of NC machining

Because of the complexity of NC processing (such as different machine tools, different materials, different tools, different cutting methods, different parameter settings, etc.), it is decided that the experience must be accumulated continuously in the long-term actual production process to engage in NC processing (whether processing or programming). 1、 What principles should be followed for the arrangement of processing sequence? The processing sequence shall be arranged according to the structure and blank condition of the parts, as well as the needs of positioning and clamping. The emphasis is that the rigidity of the workpiece will not be damaged. The sequence…

Ten Advantages and Five Limitations of 3D Printing

Unlike traditional manufacturing machines, 3D printers create objects by cutting or molding. The method of forming physical objects by stacking layers expands the scope of digital concepts from a physical perspective. 3D printer is the preferred processing equipment for shape design requiring precise internal concave or interlocking parts, which can be realized in the physical world. The following is a similar description of people from various industries with different backgrounds and professional skills. 3D printing helps them reduce major cost, time and complexity barriers. Let's take a look at the advantages of 3D printing. The advantages of 3D printing cannot…
