Zoom on Retractable Pin Principle
During the conclusion of a friction stir welding procedure, the tool pin typically leaves behind an exit hole. This remnant can be problematic for certain applications. However, with the FSW head for CNC with retractable pin, this issue is addressed. Specifically, the pin is designed to be retractable. Thus, at the culmination of the welding sequence, it withdraws seamlessly, ensuring no exit hole remains.
| Tool in two parts | The shoulder and the retractable pin are independent for an easy change and cost saving. |
| Torque transmission | The whistle notch attachment is designed for optimal torque transmission, ensuring that both the pin and the shoulder rotate in synchronized speeds. |
| Alignment | The alignment between the shoulder and the pin adheres to an H7/G6 tolerance specification. |

Users can effortlessly launch manufacturing orders, manually control operator events and adjust the retractable pin length. For ensuring impeccable weld quality, the interface presents curves of selectable values and delivers comprehensive reports on system status.
“We wanted to evolve the tool to suit our needs. Before, we used a robot arm to carry out friction stir welding. However, there are many joints in a robot. This makes it too flexible. It deforms a little when you press on the welded surface. In an operation like FSW, you lose precision. To achieve the precision we want, we needed the stiffness of a machine tool.”
