PECM for nickel- and titanium-based alloys

With its PECM technology (Precise Electro-Chemical Machining), EMAG presents a manufacturing process that offers new opportunities. PECM is a process for the machining of high-alloyed materials, such as nickel- or titanium-alloys. It is furthermore a non-contact machining method without heat transfer that eliminates tool wear, mechanical stresses and micro-fissuring through heat impact, oxidisation layering and the need for subsequent deburring operations.

Operating costs reduced by 50%

Modern vehicles are now unthinkable without laser welding. Laser welding is a prerequisite for compact, weight-optimized components and therefore for energy-efficient vehicles. You benefit from high welding speeds and minimum distortion on the welded components. Solid-state lasers offer greater power and reduce energy consumption, which can result in a reduction of operating costs by 50%. In many applications, solid-state lasers also allow welding without shielding gas. This not only reduces operating costs, it also gets rid of the annoying logistics that the use of shielding and laser operation gasses demands.

Will camshafts never again be made form a single piece of material?

Camshafts manufacturing with heat shrink assembly! The high degree of precision achieved with the assembly process drastically reduces the number of cam profile grinding operations or – with the use of precision cams – does away with them altogether. Another advantage of the process lies in the ability to combine different materials in the construction of the shaft, such as forged cams (e.g. in 100Cr6) and sintered cams, which do not require regrinding. This allows for the camshaft to be adapted to meet the requirements of the engine, and to be optimised in load bearing capacity and manufacturing costs.
