Nidec Machine Tool Corporation announced the launch of its innovative GE25CF hobbing machine, designed to streamline gear manufacturing by integrating gear cutting and chamfering operations into a single, high-efficiency process. This advanced machine is set to transform the production of high-precision gears for electric vehicles (EVs) and a wide range of other applications.
Amid growing demand for quieter and more efficient transmissions, the GE25CF addresses the critical needs of the American gear manufacturing market for enhanced productivity, automation, and reduced labor costs. By combining hobbing (a gear cutting process) with precise chamfering and deburring of both gear ends, the GE25CF significantly optimizes the manufacturing workflow.
Key Features and Benefits:
Superior Accuracy: Building on Nidec Machine Tool’s renowned GE series, the GE25CF utilizes a generating method for high-precision gear machining. Paired with ChamferX, Nidec’s dedicated cutting tool, the system ensures accurate chamfering without the metal embossment (secondary burrs) associated with traditional roll type processes. This results in a superior chamfer quality, including the ability to chamfer roots and achieve specified chamfering widths of 1 mm or greater.
Enhanced Productivity & Operability: The GE25CF incorporates a ring loader for efficient workpiece exchange, enabling simultaneous hobbing and chamfering. This integration significantly reduces cycle times. The machine also features a wider front door opening and a user-friendly operating control with a rotary joint, enhancing operator accessibility and ease of maintenance. Its compact design facilitates streamlined line layouts and supports automated, labor-efficient operations.
Dedicated ChamferX Tooling: Nidec Machine Tool’s ChamferX tools are engineered for high-speed, high-accuracy processing. Leveraging Nidec’s advanced tool design simulation and design software, ChamferX ensures precise chamfering and deburring. The tools’ long lifespan minimizes exchange frequency, while Nidec provides comprehensive after-sales services, including re-sharpening and recoating, to reduce total running costs.
Smallest-in-Class Footprint: The GE25CF boasts the smallest footprint in its class for a hobbing machine with integrated chamfering, optimizing valuable floor space in manufacturing facilities.
“The GE25CF represents a significant leap forward in gear manufacturing technology,” said Scott Knoy, Vice President at Nidec Machine Tool America. “By integrating hobbing and chamfering into a single machine, we’re enabling North American manufacturers to achieve higher levels of precision, efficiency, and cost-effectiveness. This is particularly crucial as the demand for high-quality gears in EVs and other advanced applications continues to grow.”
