Composite camshaft (joining)

Manufacturing Camshafts with a High Precision Joining Technique

Precision manufacturing of camshafts places high demands on production. The thermal joining technique offered by EMAG combines flexibility with productivity: freedom in design and production processes is matched by short cycle times.

Heat Shrink Assembly Technology is perfectly suited to the Manufacture of Composite Camshafts.

The composite camshaft continues to gain ground in the marketplace. The main reason for this is the considerable weight reduction it brings compared to its one-piece counterpart. Composite camshafts are now making inroads into the truck sector as well.

The advantages of composite camshafts are well known: lower costs, lower weight, the option of using different materials for the constituent components, greater flexibility in production and the ability to easily implement new cam geometries such as negative cam radii. Given the need to reduce fuel consumption, and with it CO2 emissions, demand for composite camshafts is ever increasing.

EMAG heat shrink assembly = precision joining

With heat shrink assembly EMAG offers a joining process that is free of reaction forces, so the cams are joined onto the tube with high precision. Of utmost importance for this is expertise in the control of the process parameters of temperature and time, as well as of the mechanical design of the joining equipment.

With an optimal combination of robots and specially designed gripping technology, joint gaps smaller than 15 µm can be reliably mastered. The concept is flexible, allowing for a lot of freedom in the design of the camshafts, and is also very suitable for medium-volume production with frequent changes of product models. The high precision of camshafts joined this way allows cam contour grinding of the shaft to be drastically reduced, or even eliminated entirely if precision cams are used. A further advantage of this process lies in the option of combining different materials in one shaft. In addition to forged cams made from materials such as 100 Cr 6, options include finish-ground cams or dimensionally accurate sintered cams that do not require subsequent finish grinding. Secondary components, such as plugs and endpieces, can be made from less expensive or lighter materials, as can the actual shaft itself. All this allows the camshaft to be adapted to suit the requirements of the engine and optimized in terms of load bearing capacity and manufacturing costs.
