R3 spinning machine
Metal spinning with precisionThe R3 Spinning Machine is a universal solution for forming sheet-metal cups or shaping specific geometries into sheet-metal parts. It offers highly versatile application options, short cycle and changeover times, strong process stability and very low tool costs. This makes it suitable for various applications in the automotive, appliance and mechanical engineering sectors where high quality combined with low manufacturing costs is required.
Machine-specific application options
The R3 Spinning Machine is designed specifically for high-speed forming of precise, rotationally symmetric hollow bodies with constant or variable wall thicknesses. A wide range of additional geometries – such as grooves or recesses – can also be produced. The machine is often used to manufacture sheet-metal cups that are later splined on the T12 cold forming machine or the i9 Internal Forming Machine. In this process, a circular metal blank is formed into a cup by applying so-called spinning rollers onto a spinning mandrel. In many production setups, the machines are linked into a production line and operate fully automatically in multi-shift environments.

FAQ
Can the R3 also be used as a stand-alone machine?
Yes, the R3 Spinning Machine can be operated as a stand-alone unit, for example for producing classic spun parts.
Can the R3 be linked with other Grob machines?
Yes. Grob machines are designed to work seamlessly together and can be linked efficiently.
How flexible is the R3 Spinning Machine?
Thanks to the well-designed tool interfaces and the modular structure of the machine, a wide variety of workpieces can be produced on the R3 with minimal changeover effort.
What are the advantages of the R3 in a production line?
By linking the machines, transfer times are reduced to an absolute minimum.
What is special about the Grob spinning process?
In the Grob spinning process, the workpiece is shaped precisely against the spinning mandrel through the local engagement of the spinning rollers. This results in parts with excellent dimensional accuracy and surface quality.
Which additional geometries can be produced on the R3?
Besides hollow bodies, grooves, recesses and other contoured forms can be produced, depending on the tool setup.
Which components can be produced with the R3 Spinning Machine?
The R3 can manufacture rotationally symmetric hollow bodies with constant or variable wall thicknesses. Various additional geometries, such as grooves or recesses, can also be formed.
Which control systems are available?
The machine can be equipped with either Fanuc or Siemens control.
