Spinning Metal Machine
1. About processing accuracy
Although the CNC spinning process is controlled by the CNC system to control the spinning wheel extrusion, the final accuracy of the spinning process is not very close to the accuracy of the CNC lathe recognized by the public, because the material's stress rebound performance will affect the accuracy of the product. The precision of spinning products is much lower than that of turning products. In addition, most CNC spinning machines have the functions of spinning and turning, but the precision of turning on CNC spinning machines cannot reach the accuracy of lathe machining molds, because spinning products are thin-walled parts that will appear during the turning process The phenomenon of deformation makes the knife vibrate, so the actual accuracy of the spinning products after turning is not as high as that of traditional turning parts.
Compared with CNC spinning and stamping and stretching, the accuracy of CNC spinning is usually lower than that of precision stretching, but in the case of relatively low material wall thickness, the strength and hardness of the drawn stamping parts are not enough because of the mouth. Deformation is easy to occur, and the precision of drawing and stamping is worse than that of spinning.
2. About manufacturing costs
The cost of CNC spinning mold is lower than stamping and drawing, the production cycle is shorter, and it is more convenient to adjust the mold. The production efficiency of most of the spinning products is not as good as that of stamping and stretching, which means that the manufacturing cost of spinning products is higher. The main advantage of CNC spinning in mass production is that the production process is flexible and the shape of the rotating body parts is processed. It is more complicated, and the metal materials processed by spinning are thicker and larger in size, which has obvious advantages in small and medium-sized mass production. In addition, the processing time of spinning single parts is long, but there are many stamping and stretching processes, which require more production personnel, logistics costs and site costs.
For some thin-walled parts of metal revolving bodies, blanks can be made by stamping or stretching first, and then finally formed by spinning, which can not only reduce production time, but also overcome the disadvantages of stamping and stretching that can not be used for necking and special-shaped products.
Brief introduction of CNC spinning process
3. About molding ability
Spinning Metal Machine's forming ability is more advantageous than manual spinning, stamping and stretching. Manual spinning is limited by human power. When the thickness of the material reaches a certain thickness, human power cannot overcome the plastic deformation force required by the material. Metal is extruded and deformed. CNC spinning has obvious advantages for thicker metals. Compared with stamping and drawing, stamping and drawing do not have obvious advantages in CNC spinning process in the fields of necking, taper drawing, or concave drawing. In addition, under the same conditions, the stretching height of CNC spinning will be Higher than stamping and drawing height.
