Electro-chemical machining (ECM) is a fascinating production method, because the technology involves virtually no workpiece contact: A direct current, or pulse, is used to polarize the workpiece positively, to create an anode, and the tool negatively, for the cathode. An electrolyte solution flows between the two, and metal ions detach from the workpiece. The components are not exposed to any mechanical or thermal stress during the process.

We’ve become the prominent leader in gear box, engines, and chassis solutions within the automotive industry but can also provide solutions within Energy, Aerospace, Agriculture, Construction and Oil Field.
Increasing cost pressure, high demands on part quality and frequent change of batches – the manufacturing of car brake discs is a difficult field. Particularly in the spare parts market, where users must request individual machining solutions that can be retooled for new workpieces without long downtimes.
This animation shows how easy it is to set up whole manufacturing systems, realized with modular machines. The example of sprocket machining demonstrates how versatile these modular machines are. Read more about the modular machines here…
EMAG ELC 250 helps with mass reduction with the laser welding of differential parts.
EMAG had seen that the world automobile market was pushing suppliers to decrease mass and reduce the overall size of driveline systems, specifically differentials. More of todays automobiles are offering an all-wheel drive or on demand four wheel drive system that require an added differential.
I continue to be amazed by the depth of product offerings that EMAG has in its arsenal – even though I have full access to all of the marketing material. However, unless one specifically seeks information on various process step combinations, these can be quickly overseen. Even our larger and more sophisticated customers often miss the opportunity to take advantage of EMAG’s unique solutions to manufacturing processes.
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.
Motion, mobility, and innovations are crucial elements of the EMAG Group philosophy. We aim to provide our industry partners with the best manufacturing solutions to complete their vision.
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?
