Principle And Introduction Of CNC Spinning Machine

CNC spinning is a complex metalworking process technology that changes the production process of rotationally symmetrical parts. It works by spinning metal sheets or tubes on a CNC-controlled CNC spinning machine while applying pressure through a dedicated spinning tool to plastically deform them into an axisymmetric shape. The process is able to create complex geometries with high precision and repeatability.

CNC Metal Spinning Process Flowchart And Case Studies:

CNC metal spinning is divided into 6 key manufacturing processes that can form metal into various cylindrical shapes.

1.Stretch Metal Spinning

Stretch metal spinning refers to the process of fixing a metal sheet disc between the machine mold and repeatedly spinning and stretching the metal spinning wheel tool; the metal sheet will be thinned to fit the mold contour.

2.Shear Metal Spinning

Shear metal spinning refers to fixing a metal sheet disc between the machine mold. When the product contour shape is a cone or a cone, and the single-side angle must be greater than 20°, the metal spinning wheel performs a single-pass spinning on the cone workpiece. This process requires high precision and strength of the machine.
Between 20°-30°, the thickness of the sheet is greater than 4MM;
Between 30°-40°, the thickness of the sheet is greater than 1.5MM;
Greater than 45°, the thickness of the sheet is greater than 0.8MM;

Calculation formula for spinning wall thickness: T(metal sheet thickness) * (Sin* A° cone angle);
For example: the wall thickness of the round sheet material: 2.0mm, the angle between the single side of the product and the axis is 40°; 2*(Sin*40)=1.28 (data for reference, different metal materials have different hardness, and the gap between the metal spinning tool wheel and the mold needs to be adjusted relative to each other)

3.Necking metal spinning

Necking metal spinning refers to fixing the metal pipe or barreled metal blank in a special mold or fixture, and repeatedly spinning the metal on the mouth or waist of the metal with the metal spinning wheel. This process is a special process of metal spinning! It solves the problem that the water bulging machine and traditional tube shrinking machine cannot change the diameter significantly.

It is mainly used in milk cans, chemical barrels, energy storage cylinders, hydrogen cylinders, and other pressure vessels with high pressure and airtightness!

4.Expanding metal spinning

Expansion metal spinning refers to fixing the metal pipe or barreled metal blank in a special mold or fixture, and the metal spinning wheel repeatedly expands the metal from the inside of the workpiece to the outside; this process is a less used process in metal spinning, and its mold tooling design is relatively complex! This process is opposite to necking metal spinning, and the corresponding process selection is mainly based on judging the ratio of the metal spinning part to the original pipe part.

5.Tube Thinning metal spinning

Tube Thinning metal spinning refers to fixing the metal tube in a special mold or fixture, and multiple sets of symmetrical metal spinning tool wheels thin the wall thickness of the tube to increase the length of the metal tube! The main feature of this process is that the wall thickness accuracy after metal spinning is high, the length of the machine is long, and the diameter is generally not large! The assembly accuracy of the equipment is quite strict, so the price of the machine is much more expensive than that of ordinary spinning machines. Due to the installation method of the special spinning wheel of this machine, this process is mainly used in room temperature metal spinning process.

This process is widely used in aerospace, military industry, energy storage, hydrogen cylinders and other long tube processing.

6.Spin Flanging Metal Spinning

Spin Flanging Metal Spinning refers to fixing a metal reel with a larger diameter on a special tensioning fixture or hydraulic chuck, and the flanging spinning wheel with rotary power tightens the edge of the reel, driving the workpiece to rotate on the main shaft. The flanging spinning wheel is controlled by the program to perform 90° flanging or bell-mouth spinning on the reel; this type of machine generally has a graduated punching function. After the flange is formed, the main shaft realizes power access through a complex clutch, the servo motor makes the workpiece accurately indexed, and the hydraulic punching mechanism starts working after receiving the indexing signal from the encoder.
Spin Flanging Metal Spinning is most commonly used in the manufacture of wind tubes for industrial axial fans and tunnel and subway jet fans.

Summary CNC metal spinning encompasses a variety of technical applications, and different process technologies are suitable for specific applications. Stretch metal spinning, shear metal spinning, shrink metal spinning, expansion metal spinning, tubular metal spinning and rotary flanging provide a variety of solutions for accurate and efficient metal forming.
Understanding the metal spinning process helps you choose the process production options for manufacturing high-quality metal. Altron also supports you to customize the perfect metal forming solution department and automated machine for your workpiece! 

Advantages of CNC Spinning Machines

CNC spinning is a precision metalworking process that offers several advantages over traditional deep drawing methods.

CNC spinning machines are able to accurately form and guarantee the consistency of various metal materials during the spinning process (including special alloys such as aluminum, iron, copper, stainless steel and titanium). Secondly, CNC spinning improves productivity by reducing development time and minimizing material waste. In addition, CNC metal spinning helps to produce complex geometric rotational shapes without the need for high-powered machines and complex processes, thereby greatly reducing manufacturing costs.

The spinning machine recording and replay programming system is a set of software and hardware CNC systems developed for manual spinning engineers.
The system hardware consists of an industrial computer with WINCE system, a PC with WIN7 system and a Hall 360-degree rocker.
The special spinning programming system has strong anti-interference ability and stable operation. The running trajectory of the spinning roller is controlled by the rocker. During the spinning process, the running trajectory of the spinning wheel can be adjusted at any time according to the deformation and rebound of the material. The system will record all the spinning data information such as trajectory and speed to automatically generate the CNC spinning program for parts, so as to achieve an auxiliary system to prevent manual spinning.
