The sheet metal stamping is one of machining process, It's also named pressing. Stamping is a forming method to use presses and dies to exert external forces on plates, strips, pipes and profiles, resulting in plastic deformation or separation, thus obtaining the desired shape and size of the work piece. (Stamping parts) .Stamping and forging belong to plastic processing(or pressure processing), collectively known as forging. The blanks are mainly hot-rolled and cold-rolled steel sheets and strips. Of the world's steel, 60 to 70% are plates, most of which are stamped into finished  cnc machine parts . Stamping processing is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, which makes the sheet material be directly deformed and deformed in the die. Sheet metal, die and equipment are the three elements of stamping. It is divided into hot stamping and cold stamping according t...

Surface processing of CNC metal parts: 1. Spray paint processing: the hardware factory adopts spray paint processing in the production of large pieces of finished  metal machined parts . By spray paint processing, the  metal machined parts  can avoid rust, such as daily articles, electrical shells, handicrafts, etc. 2.Electroplating: electroplating is also the most common processing technology for  CNC metal parts  processing. Through modern technology, the surface of hardware is electroplated to ensure that no mildew and raw embroidery will occur when the product is used for a long time.  3.Surface polishing: Surface polishing is generally used in daily necessities. Surface burr treatment is performed on  CNC metal parts . For example, we produce a comb, which is a piece of  CNC metal parts  that are stamped, so the corner of the comb is very Sharp, we have to polish the sharp part of the corner into a smooth face, so that it will not cause ...

CNC technology is a technology that uses digital information to control mechanical motion and work processes. The application of CNC technology not only brought revolutionary changes to the traditional manufacturing industry but also made the manufacturing industry a symbol of industrialization. ​ CNC machine tool is a high, precision, pointed technology in one, set machine, electricity, light, the liquid in one of the high-tech products. It has many advantages such as high processing precision, stable and reliable processing quality, high production efficiency, strong adaptability and good flexibility. It becomes popular in various industries and is receiving more and more attention in terms of use. To use the CNC lathe for turning parts, first of all, a step-by-step determination plan should be made, that is, the preparation work before the operation is clearly defined. The principle of positioning benchmark selection 1) The principle of benchmark coincidence. In order to avoid the r...

In the process of processing  machining parts , arranging the heat treatment process reasonably can make the cold and hot working procedures cooperate better and avoid the deformation caused by heat treatment. Do you know how to arrange the location of heat treatment reasonably? 1. Preliminary heat treatment:  The purpose of the preliminary heat treatment is to eliminate the internal stress produced in the manufacturing process, improve the cutting performance of the metal material, and prepare for the final heat treatment. The preparation of the heat treatment is tempered, annealed, normalizing, etc. And after work, it is beneficial to eliminate residual internal stress. 2. Final heat treatment:  Final heat treatment should be arranged after rough machining and semi-finishing, before or after fine finishing. Heat treatment with large deformation, such as carburizing, quenching and tempering, should be arranged before fine finishing in order to correct the deformation of ...

NPT, PT, G are all pipe threads. Now we will introduce information about thread type to you.  NPT is the abbreviation of National (American) Pipe Thread. It is a standard American 60 degree taper pipe thread. It is used in North America. The national standard can be consulted in GB / T12716.  PT is the abbreviation of Pipe Thread, which is a 55 degree sealed conical pipe thread. It belongs to Wyeth thread family and is widely used in Europe and some Commonwealth countries. G is a 55 degree non-threaded sealed pipe thread, and it belongs to the Wyeth thread family. It is marked as G, which represents cylindrical thread. The national standard can be found in GB/T7307. In addition, 1/4, 1/2 and 1/8 in thread refer to the diameter of thread size, and the units used are inch. Insiders usually use the points to refer to the thread size, one inch is equal to 8 points, 1/4 inch is 2 points, and so on. G is the general designation of pipe threads (Guan). The divisio...

Forging is the use of an impact or pressure to deform the metal in the iron or forging die to obtain the desired shape and size of forgings. This type of process is called forging. Forging is one of the important forming methods for metal parts. It can ensure that metal parts have good mechanical properties to meet the requirements of use. It can be called hot or cold forging by whether the metal temperature is above or below the recrystallization temperature. Hot Forging Process Hot forging process is a metalworking process in which metals are plastically deformed above their recrystallization temperature, which allows the material to retain its deformed shape as it cools. It is performed at the highest temperature which does not destroy the metallurgical features of the considered alloy (up to 1250°C for steel, 300 to 460°C  for Al-Alloys, 750 to 1040°C for titanium alloys and 700 to 800 °C for Cu-Alloys). Hot Forging Advantages(VS cold forging) ●Elimination of chemical impuritie...
