A continued rise in the demand for customized systems and integrated solutions was predicted back in 2014 by a survey of German manufacturers of plant and machinery, in a study on the future perspectives for the industry in Germany. This is not surprising given the huge “Industry 4.0” trend, as extensive automation in the form of customer-specific system solutions is a fundamental prerequisite for the digitalization of production facilities. The machines used then form an integrated system that production planners can control from a central point. Moreover, many companies need to respond ever more quickly and flexibly to technological developments. Numerous different versions of parts and fluctuating unit volumes are typical for small and medium-sized production companies in the automotive industry.
Technologies
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.
The EMAG Inverted Spindle Pick-Up Lathe process provides for a significant improvement in accuracy versus that of a sub-spindle lathe.
Lathes with sub-spindles pass a part from one rigid work holding system to another. This does not allow for any misalignment of the two spindles. The first spindle cannot release a part until the second spindle has a secure grip on it. Allowing for mismatches on a split turned dimension such as a bore. The accuracy and quality of the workpieces that are produced from this system are compromised because of this process.
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.
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.
When a leading tier 1 automotive manufacturer came to EMAG and asked us to meet their goals and needs for new differential lines, we had our work cut out for us. One of the unique promises made by EMAG is the company’s ability to achieve each customer’s needs. With this customer, their needs/goals included:
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.








At EMAG, we know that the manufacturing market on the East Coast is an important one and with that in mind, we decided to plunge into EASTEC 2017 – and we’re so happy we did!
Today’s competitive talent marketplace requires small and medium contract manufacturers and OEM’s to make the most of the talent they have. Skilled, experienced machinists are hard to find and having them tied up hand-loading parts into a lathe is seldom the best use of talent. So – how does a successful small to mid-sized shop meet their customers’ production requirements with the existing talent pool?
