The FSW Fork head
incorporates the finest technologies produced by Cytec.
Besides the powerful 42kW Cytec motor spindle with an HSK-A 100 tool-interface, the CyWeld is equipped with 6 spherical arranged shear force transducers.
These sensors are used to detect the radial and axial forces during the welding process in TCP derection.
The FSW Motor Spindle
FSW robot spindles for friction stir welding and milling with articulated arm or parallel kinematics robots
Characteristics :
• HSK tool interface with hydromechanical Cytwist tool clamping system
• CyTorque motor (combinable with all common control systems)
• Pre-loaded hybrid bearing
• Shear force transducers to regulated forces during the welding process
• Rotary feedthrough for clamping and release hyrdaulics
High surface finish, less process force and heat, highly dynamic welding enabled by non-rotating tool shoulder separate retraction of the Pin or separate pushing shoulder.
This special join process is more sensitive and a good alternative to great better surface finish. The friction pin rotates into the mate-rial. The non rotating shoulder gives a slight pressure to the welding surface. This process create less force and heat. This type of FSW tool is often used on thin workpieces. With the Flextool an axial shoulder compression at the end of the welding process is possible. During the shoulder stay on the surface the Pin returns from the material.

Automatic Tool Clamping system
Cytec Friction stir welding spindles and heads are equipped with an automatic hydromechanical tool clamping system and shear force transducer for an optimal force regulation during the welding process. The Flextool and CyStir motor spindle offers further automation solutions to seal the weld seam.
The tools are inserted either manually or by a pickup station into the tool interface.
The PLC triggers the hydraulic operation to lock the tool high clamping force.
The tool clamping is controlled by an analog volume flowmeter combined with an electronic evaluation device integrated in the control cabinet.
