ニデックマシンツール（前：日本電産マシンツール） Company Overview

In June 2021, we launched the new hob machines "GE15HS" and "GE25HS," which emphasize high precision and high efficiency. The GE15HS accommodates gears with a maximum diameter of 150mm and employs a high-speed, high-torque direct drive motor for the spindle, increasing the maximum spindle speed to 6,000 min-1, three times that of conventional models. Additionally, the table axis, which holds the workpiece, features a dedicated table that achieves high-efficiency machining by combining high rigidity with high-speed rotation, capable of handling thrust loads necessary for efficient processing. Furthermore, machining with carbide cutting tools achieved a surface roughness of Ra0.4 or less, comparable to gear grinding. On the other hand, the GE25HS accommodates gears with a maximum diameter of 250mm. To ensure high-efficiency machining, it incorporates a high-speed, high-power spindle that eliminates the impact of temperature rise on machining accuracy during high-speed rotation, as well as a standard high-rigidity table equipped with a backlash elimination device for the table master gear. The motor torque and maximum spindle speed have been increased to approximately 1.5 times that of conventional models, reducing machining time by 42%. Moreover, by combining our new materials and coatings for cutting tools, stable mass production machining is possible even in high-speed areas exceeding cutting speeds of 400m/min.

In March 2021, we launched the gear shaper "SE25FR Plus," specialized for high-precision small modular gears used in robots. We also released dedicated cutting tools for small modules compatible with this machining system, responding to the growing demand for high precision in precision reduction mechanisms required in the expanding global robot market. The SE25FR Plus achieves high rotational accuracy by employing a direct-drive motor and ultra-precision bearings in its core components, the table and cutter head, which are essential for high-precision wave gear devices. This allows for a gear machining precision class of ISO Class 3, enabling more precise cutting compared to the ISO Class 6 SE25FR. Additionally, the small modular cutting tools launched simultaneously with the SE25FR Plus feature newly developed specialized tool materials and a coating for micro-machining called "MightyShield μ." The tool materials utilize carbide with enhanced toughness and wear resistance, while the coating is applied uniformly in a thin film of less than 2μm, which does not affect tooth profile errors, achieving excellent machining surface shapes and meeting "sub-micron" level tooth profile requirements even with difficult-to-cut materials.

◆Expansion of lineup with new product launch ◆Response to a wide range of market needs for large component processing Nidec Machine Tool Corporation has launched the "MVR-Cx series" of gantry machining centers as its first new product release since becoming a subsidiary of Nidec Corporation. - Announced in a press release on October 5, 2021 (please refer to the attached press release for details) - <Product Page> https://www.nidec-machinetool.com/product/mvr-cx/
