When precision counts in electrochemical machining, the tool cathode plays a significant role: Its shape determines the removal of material at the workpiece. Therefore, its design and precise production is a particularly important machining task in the micrometer range. For its development, EMAG ECM therefore has a large development area with a largely digital workflow.

eldec has been a part of the EMAG Group for over four years. Cooperation among our companies has not only been profitable for us, it has also been beneficial for our customers. Together we have developed several new induction heating processes that integrate the hallmark EMAG multi-function process flow in new production lines. At the same time, eldec generators and inductors can be found in many EMAG joining and laser welding systems. Working together we drive induction heating technology forward, allowing for better performance, shorter heating cycle times and even more precisely regulated heating.
The VLC 200 GT is loaded at by the integrated pick-up spindle. The process starts with hard pre-turning of the shoulder and the bore hole in quick succession. Only a few micrometers of material are then left to be removed from the automotive gear by the subsequent grinding process, using either aluminum oxide or CBN grinding wheels.
Transmission manufacturing is among the most innovative areas of passenger vehicle production: This central component has to ensure a high level of driving dynamics, while keeping fuel consumption low at the same time. Transmissions are therefore becoming smaller and lighter, and provide a higher number of speeds. The individual gearwheels are a main focus of the developers. Their production in extremely high volumes requires a high level of efficiency—at high precision, high speed, and highly controlled.

In the automotive industry, one trend has been consistent for years: Passenger vehicle transmissions are becoming smaller and lighter, although the number of speeds—and of toothed gear components—continue to increase. How does the entire assembly not become heavier?
Maximum Efficiency in Shaft Production. Short cycle times, high precision and safe processing are among the outstanding attributes of shaft machining on the turning machines of the VT series. These lathes literally turn the classical horizontal machining process on its head.
