Nidec Machine Tool Develops the World-first Internal Polishing Process for Mass-production - For the Quality Improvement of EV, Robot, and Other Gears
NIDEC Machine Tool Corporation (“Nidec Machine Tool” or the “Company”), a group company of Nidec Corporation, today announced that it has developed the world’s first high-accuracy internal polishing process for mass production. It can finish ring gears in planetary gear sets that are used for automobiles’ transmissions and robots’ joints. Gear polishing was well established for external gears in mass-production, but for internal gears, it was still at the development level. After conducting research focused on this point, the Company has achieved positive results to secure a level of accuracy with high productivity for mass production, which could not be obtained by conventional internal grinding, honing, or skiving process.
Planetary gear reduction mechanism can provide a higher transmission ratio in a significantly more compact and lighter package, and a positive effect on the efficiency. For this type of gear, even the slightest geometric distortions in the ring gear lead to unwanted noise, vibration, and negative influence on durability, and efficiency. The demand for highly accurate gears is increasing because of the electrification of automotive and automation for manufacturing. The Company has realized the development of this new finishing method can satisfy demand and improve gears’ durability, transmission efficiency, and NVH (noise, vibration, and harshness) performance.
Through this latest R&D project, machining process evaluation was conducted by Nidec Machine Tool’s gear grinding machines and technologies. This project is part of the joint research with RWTH Aachen University, Germany.
Processing machine:
ZI20A, the internal gear grinding machine developed by the “Company” with unique technology and launched in 2009, was used. This machine can satisfy high accuracy and high productivity for mass production applications.
Selection of polishing wheels:
Polishing wheels were selected through preliminary assessment by evaluating their availability in the market, economic efficiency, and suitability for mass production application.
Definition of machining conditions:
The target surface roughness was set to Ra0.1µm and Rz1.0µm or less as a general surface roughness requirement for polishing. The high-efficiency process conditions that can keep geometry accuracy, ISO class 3 to 5, without grinding burn were defined.
With its world-leading gear-machining technology, Nidec Machine Tool provides machines, tools, and machining solutions to stay committed to contributing to solving social issues.

Nidec 17S系列FFC业者追加-20241210
描述- 住友电工（SUMITOMO ELECTRIC INDUSTRIES CO.,LTD）目前为FFC供应商，但因其供应周期较长（6-12周）无法满足生产需求。为解决此问题，拟追加广西容县凌通竟业电子（SHS HARNESS MANUFACTURER LTD）为FFC供应商。两公司产品在外观、耐热温度、耐压等级、难燃等级等方面一致，且广西容县凌通竟业电子的FFC品质和纳期可满足生产需求。需确认是否进行样品评价。
