product introduction

The Y31800B, Y31800C, and Y311250C represent the pinnacle of gear hobbing technology, addressing workpiece sizes that approach the practical limits of hob-based machining. These machines incorporate oversized spindle bearings, reinforced column sections, and heavily ribbed beds that distribute cutting forces efficiently across the entire structure. The feed system on all three models incorporates load-sensing technology to optimize cutter engagement as tool wear progresses, while advanced condition monitoring systems provide real-time vibration analysis to protect critical components.

All three machines serve the most demanding applications: wind turbine main shafts, marine propulsion systems, large kiln drives, and rolling mill stands. The progressive power and capacity tiers allow manufacturers to select the optimal configuration for their specific workpiece portfolio.
