4-axes-FSW gantry systems of the DSM series

Friction Stir Welding with a perfect result

Sealing for many industries and concerns: Grenzebach has developed the compact 4-axis gantry machines of the DSM series (DSM = Dynamic Stirring Machine) specially for the requirements of the FSW process. The focus of the machine design was a dynamic and precise process control as well as an intuitive control and operating concept.

 

The 4-axis gantry system is designed for high dynamics and precise path guidance. All this in the HYDROPOL® machine bed, which is specially designed for very high static stiffness, low dynamic compliance and deformation.

 

  • Integrated C-axis allows a rotation of the welding head by +/- 720 °

  • Far higher dynamics for complex welding paths with narrow radii

  • Working range: DSM1400 1,400 x 1,000 x 400 mm or working range: DSM2400 1,400 x 2,400 x 400 mm

  • Further dimensions upon request

Welding with low-distortion at the highest level for perfect results - fast, dynamic, precise.

  • Gantry traversing speed upt to 13 m/min

 

  • Welding speed up to 3 m/min

 

  • Accuracy during the process +/-0.1mm

Machine and process control with IndraMotion

With the MTX control by Bosch Rexroth, Grenzebach relies on well proven CNC control technology and combines this with innovative FSW process control. Adapted software interfaces also allow an easy connection to a higher-level control system. The machine and process programming is made easier via FSW CAD/CAM programming software.

 

 


Everything under control

  • All parameters and machine data at a glance via touch panel
  • Handheld controller for a manual control the axes
  • The welding process is completely under control due to the large windscreen
  • Optional live image camera
  • Handling of heavy assemblies and fixtures with a crane or robot outside of the machine
  • Protected access to the complete working area of the machine
  • Maintenance access points on the backside allow the accessibility to the controller hardware and the central power supply at all times

Modules for different customer needs

Friction stir welding at the height of time: The 4-axis FSW gantry systems of the DSM series offer numerous additional features to fully meet individual requirements at any time:

 

  • Complete recording and output of all process- and quality-relevant machine data

  • Configurable, automated tool changing station for quick tool change

  • Sensors for calibrating fixtures and components

  • Media supply for DSM shuttle systems (pneumatic, hydraulic, electric)

 

 


Workpiece supply systems for enhanced productivity

In terms of cycle time, the rapid loading and unloading of workpieces is just as important as the dynamics and speed of the welding machine. Modular, expandable, automatic feeding systems for simultaneous welding and loading / unloading of work pieces outside of the machine. The loading and unloading of components can be done manually by the operator with the help of a manipulator or an indoor crane, or fully automated.
