Example of added value solution to Power Transmission industry.
In its 12 years of history ICT srl has developed long term partnerships in Europe and in Asia in order to provide added value solutions to bearings, automotive, ball screws and cv-joints industries. The last partnership in the area of forged, rolled, turned and heat-treated rings allows the company to talk about one example of smart solution (friction welding technology) to produce double gears.
Friction welding refers to joining two metallic surfaces by the frictional heat generated at their interface due to relative motion applied between them. The parts being joined are held under high compressive load. As the frictional heat starts to soften the materials at the interface, the applied compressive load creates a hot forging type action that forms a metallurgical bond between the two surfaces. The joint thus produced has a narrow heat affected zone in the plastically deformed zone adjacent to the joint, but no fusion zone. If there is any flash or extruded material on the sides, it can be removed by a later operation.
ICT partner applied such technology to produce double gears through a manufacturing process that includes the following steps:
- Forging
- Pre-machining
- Friction welding
- ISO Thermal annealing
- Final turning
Special procedures for the operations and for the controls and testing have been developed by process engineering and quality team in order to supply hundreds of thousands of components made by such technology during the last few years.
Advantages for the customer and the applications are several with respect to the traditional production process. However, the main ones can be summarized as it follows:
- Drastically reduced input material (much lower manufacturing cost);
- Better fibres flow, resulting in a longer life in endurance tests.
