Which sector of industry is the most innovative in Germany? A very comprehensive answer to this question has been provided in the report entitled “Innovation in the German Economy” issued by the Center for European Economic Research (Zentrum für Europäische Wirtschaftsforschung GmbH, ZEW). The current issue rewards automotive manufacturing, among others, with a good score. According to the report, the automotive industry has the highest amount of innovation in its production (48.3%). Innovation is fundamental to the automotive industry’s economic success. Additionally, the industry’s “innovation expenditure” identified by the ZEW is increasing. In 2016, this was valued at 47 billion euros and, according to estimates; it should increase to nearly 55 billion euros by the end of this year.

Electric power steering has become standard in the manufacturing of automobiles. The technology guarantees very precise steering support for every type of vehicle, high-end driving comfort, and lower energy consumption in the steering system, which has a positive effect on the car’s CO2 consumption.
The revolution in car manufacture is happening subtly: Our cars are mastering an increasing number of situations without driver intervention. There is a large number of assistance systems which keep the vehicle on track or avoid obstacles. Recent models even park independently or drive into the garage. This requires the driver to take their hands off the steering wheel entirely. Experts divide the current development into phases: The assistance systems described above have already become a reality. As a partially automated system, parking assistance belongs to phase two. In a few years, fully automatic, driverless operation will follow as the last phase.
Cylindrical grinding on driveshafts and transmission shafts has always been particularly demanding, as the parts feature a wide range of geometric details that are machined with high precision in the grinding machine. With the rapid pace of technological development in the automotive industry, which keeps increasing the functional density of many components, there are more demands than ever on the design of grinding machines today. Users require highly customized machines that can perform multiple grinding operations, including combined internal and external grinding.
Lightweight construction in the automotive industry is a fight for every pound. Every single part is investigated for whether it could be made even lighter. This is typically accomplished by using new materials of changing part geometries. Laser welding offers a surprisingly simple strategy, e.g. by enabling a stable connection between differential gear and ring gear. This saves screw connections and reduces weight by 1.2 kg – quite an accomplishment by the standards of the field.
CVT transmissions are becoming increasingly popular in the American and Asian markets. The technology improves driving comfort as the car shifts gears more smoothly. A critical part of manufacturing these transmissions is the creation of the CVT components like shafts and disks (“pulleys”) that need to be hard machined with extreme precision– all as part of a multi-stage process that uses various turning centers and grinding machines.
The automotive world is constantly changing and improving. The industry strives to create vehicles with better fuel economy, while also increasing safety and reliability.
The introduction of hybrid and electric alternatives are becoming more popular, and in the years to come we will see these options continue to grow. With this change, certain components of today’s gas driven engines will be replaced with new components and technologies.
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.
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.
