Three Wheels CNC Metal Spinning Machine
Three wheels CNC metal spinning machine is suitable for forming some small diameter workpieces with long length, for example, it is able to realize the forming of cylindrical parts and small angle conical products. If you are looking to do something similar, then I believe that Altron’s machine will meet the need for high precision and quality effects.
The features of Three Wheels CNC Metal Spinning Machine
- Top equipment, reliable and durable
The main body of the machine is made of casting structure, with Siemens CNC 828D and servo motor control. And it adopts three wheels with 120° distribution. It has high precision, stability and reliability as well as low failure rate.
- Intelligent software, flexible and convenient
The machine is equipped with special spinning programming software developed by our company, which can automatically generate the program as long as the trajectory is drawn, which is quick to operate and flexible to adjust.
- Powerful and easy to cope with
Adopting high-power servo spindle as well as strong radial thrust, it can easily cope with spinning carbon steel, stainless steel, aluminum and other materials, with high molding efficiency and excellent quality.
Composition and working process of the equipment
The equipment consists of 5 main parts, there are spindle part, slide part, tailstock part, workpiece cooling part, hydraulic system, electrical system.
In the preparation stage, the mold and sheet metal are installed first, then the machine’s loading tail top moves forward to press the blank tightly onto the mold. The parameters are set and then the machine starts to spin, the spindle drives the mold and the blank to rotate at high speed. Three spinning wheels spin the blank according to the pre-set trajectory. When the metal flow is formed, the spinning wheels and tail top return to their original position. Finally, unloading is carried out.
In the spinning process, the metal will be pressurized to flow along the axial and radial direction and undergo tensile distortion. So after the spinning of CNC spinning machine, the wall thickness of the workpiece will be gradually thinned, probably the wall thickness thinning rate reaches 50%-60% of the original thickness. Therefore, this equipment is very suitable for raw materials with large thickness. The following case is the thickness measurement of our workpiece after molding.
Why choose the spinning technique instead of the deep-drawing technique?
Cold extrusion presses machine extrudes the metal material into the mold by high pressure and plastic deformation. It needs to make corresponding deep drawing molds according to different sizes of workpieces. And the time for making the mold is also longer. But the workpiece processing and molding process time is short, cold extrusion once formed. So it is suitable for mass production of the same size workpiece. On the contrary, it is inconvenient and costly for projects in the development stage.
If the CNC spinning technique is chosen, the development cycle can be shortened considerably. The machine is equipped with special programming software can automatically generate programs, according to different workpiece size requirements to flexibly adjust the parameters. In contrast to cold extrusion presses, CNC flow forming machines use less costly molds. So CNC spinning presses are suitable for projects in the development stage, small to medium batches or multiple varieties of precision metal products.
| Thinning Wall Thickness | Applicable Output | Texture Effects | Timing | Flexibility for Mutiple Products | |
| Spinning | Gradual thinning | Small and Medium Volume | Spiral | Longer forming time; short time for making molds | Very flexible |
| Cold Extrusion | Uniform thinning | Large Volume | Smooth | Short forming time; long time for making molds | Inflexibility |
How to choose the Three wheels metal spinning machine?
Drawings with parameters such as material, thickness, diameter and length of the product are required to determine the appropriate model of three-wheel spinning machine.
It also depends on the metal spinning technique that the customer wants, Altron will provide a specific plan with professional analysis. For example, some of them may need to be hot for processing, to be annealed to improve the mechanical properties of the workpiece.
Application of the three wheels spin forming metal machine
Three wheels spin forming metal machine is widely used in automotive, chemical, aerospace and other production fields. It replaces traditional welding and eliminates the weak points of the welding seam. It realizes integrated molding and makes the structure more reliable. It meets the needs for robustness, reliability and consistency of products in many fields. In addition, combined with the Necking machine can be made into gas cylinders. The three wheels spin forming metal machine is used to spin a long cylinder, cut it to length, and then hot-spin the neck to reduce the mouth of the cylinder.
Spinning technology is also widely used to enhance the quality of daily industrial products, such as forming a variety of artistic lamps and kitchen utensils, the beautiful surface combined with high-grade metal texture, to enhance the appearance of the product grade and internal quality.
