Flexibility in the workpiece range of E-Mobility

E-mobility has brought about various application areas with new challenges for gear manufacturing. From miniature gears in bicycle drives to the gears installed in cars and even larger workpieces in trucks - KAPP NILES machines offer the flexibility to meet a wide range of requirements.


The majority of electric cars use simple, non-shiftable transmissions consisting of input shaft, intermediate gear, intermediate shaft and differential gear. However, the demands on these gears are even higher due to the extremely wide speed and torque range. KAPP NILES offers the answer for reliable machining of these workpieces with highest quality.

When top speed is required in an electrically driven sports car, transmissions have to function under maximum load.

The demands on the quality of gears have increased by leaps and bounds, not only in passenger cars but also in electrically driven commercial vehicles. Higher torques must be transmitted over a wide load range with high efficiency. At the same time, durability plays an important role.

To support you in meeting these requirements, we have advanced our grinding and measuring machines as well as their machining processes and chains accordingly.

Find out how you can effectively and economically machine the required range of components in our success story "Electric truck: Polished gears in XXL".

Gears for bicycle drives are both very small and difficult to machine due to unfavourable workpiece geometries. Nevertheless, solutions are needed to manufacture these components in an equally productive, economical and consistent quality manner. All previously known fine machining processes have reached their limits here. Only through the development of generating grinding with the smallest tools is there a process that meets all requirements. KAPP NILES grinding machines with high-speed grinding spindles (HS) up to 25,000 rpm and correspondingly dynamic workpiece drives up to 5,000 rpm provide you with the basis for using this technology. This enables you to machine even the most complex gears precisely and efficiently.

"Particularly with the varying and constantly increasing requirements for transmissions of electrified vehicles, it is always impressive to see how profound the knowledge of KAPP NILES is in this area. Here, the expertise goes far beyond the limits of the grinding machine, which is a prerequisite for understanding current customer requirements and translating them into a grinding process.“

Dr.-Ing. André Wagner - Head of Grinding Technology | Hermes

„Together with KAPP NILES, we were able to work on a number of interesting research projects on the hard fine machining of gears. The highlight was certainly the integration of the polishing process directly on the gear grinding machine - which is now indispensable for a wide range of applications in the field of e-mobility."

"E-mobility needs high-precision gears, high precision gears need high precision diamond dressers and for high precision dressers we have KAPP NILES!"

Baocheng Feng - Tool Management Manager | Shuanghuan

"KAPP NILES is an invaluable partner in realising the complex gear tooth geometries that are needed for race and hypercar transmissions. We use their experience and support in both the profile and generate grinding technology for gears of the highest quality for quiet operation and for durability."

Martin Halley - Production Engineering Director | Xtrac

"E-mobility projects are very easy to realise with KAPP NILES. KAPP NILES is a competent supplier for e-mobility and offers top quality for every application."

Jürgen Kempf - Head of Technical Application Consulting and Sales | König MTM

"Manufacturing engineering is major key to economically and ecologically balanced powertrain production. KAPP NILES supports production-based innovation in FVA giving impulses and know how for innovative and up-to-date research projects. On the other hand KAPP NILES is lead applicator of FVA research results to set the pace for excellent production equipment and machines."

Dipl.-Ing. Christian Kunze | FVA (Research Association for Drive Technology - Support Association MOBIMA e.V.)

"KAPP NILES gear grinding machines have a reasonable layout, smooth automation system and excellent rigidity. After decades of years of advancement and optimisation, they have always remained in the first front of worm gear grinding machines. In particular, the KX 300 P and KX 260 TWIN models continue to provide excellent stability and efficiency in the grinding of e-mobility gears, providing a good machining experience for the user."

Wu Youxiang - Manufacturing Engineering | Shuanghuan

"We completed long test runs of the gearbox with the development department. This resulted in change requests to the process and the tools, which always had to be implemented under time pressure. I had a contact person at KAPP NILES at all times - even at weekends if things had to be done quickly. This meant that we had a new batch of prototypes in the shortest possible time with which we could go to the test stand. KAPP NILES helped us a lot during the prototype phase of our new development for a fully electric transmission for a super sports car and was always an optimal partner for us."

Roberto Di Geronimo - Competence Leader Gears & Gauges | FPT

"Highest quality through first-class cooperation: With KAPP NILES we realise a large number of innovative clamping solutions for gears. An absolute win-win situation with maximum benefit for our joint customers."

Thomas Hübl - Head of Key Account | Hainbuch

"The investment in a KAPP NILES gear grinding machine was the basis for our competence development in gear hard machining. With the flexibility of this machine, we can map all current research topics in gear grinding around e-mobility."

Carsten Hochmuth | Fraunhofer IWU, Chemnitz

„With KAPP NILES we started the demanding topic of e-mobility gears at a new production site. We got perfect support for the package consisting of gear grinding and measuring machine.“

Elias Häggström - Director of Gear Technology | LEAX
