Nidec Machine Tool, a division of Japanese electric motor manufacturer Nidec, has introduced the GE25CF — a next-generation hobbing machine engineered to enhance productivity, automation, and labor efficiency in the production of high-precision gears.
Designed as a process-intensive solution, the GE25CF combines multiple operations into a single system. It performs hobbing, chamfering, and deburring in one streamlined machining process. This integration helps reduce cycle times while improving the precision and surface quality of gears.
Traditionally, chamfering — the process of beveling gear edges — has been done using phrasing, a plastic deformation method that can leave undesirable metal embossments. In contrast, the GE25CF employs a generating-method-based cutting system, allowing for more accurate and consistent chamfering. This method minimizes surface defects and ensures superior tooth flank and end face quality.
Central to the GE25CF’s innovation is ChamferX, a proprietary cutting tool developed by Nidec. It enables high-efficiency chamfering with precise control, allowing chamfer widths of 1 mm or more and the ability to chamfer gear roots — a task typically challenging for phrasing systems. ChamferX also removes burrs formed during the hobbing process, further improving finished product quality.
The GE25CF is designed with usability in mind. Its front door features a wide opening for easy access, while the control panel includes a rotary joint for flexible operation. A narrow chamfering unit profile allows for compact production line configurations, making the machine suitable for modern, space-conscious manufacturing environments.
With the launch of the GE25CF, Nidec aims to provide manufacturers with an efficient, high-precision gear cutting solution that addresses growing demands for automation and consistent quality in industrial production.
