CNC gear-hobbing machine YK series

verticalfor large-diameter parts

Overview

• Vertical gear hobbing machines are CNC gear machining equipment that uses hobs to process gears using the generating method. With a vertical layout as its core structure, it combines high rigidity, high precision, and high efficiency. It is mainly used for the batch and precision machining of various cylindrical gears and worm gears, and is a core piece of equipment in the gear manufacturing industry.

Key Features

• Stable Structure: Adopting a vertical column + worktable layout, providing high rigidity and low vibration, suitable for machining large-diameter and large-module gears.
• High Machining Accuracy: Capable of machining spur gears, helical gears, worm gears, and synchronous gears with stable tooth profile and direction accuracy suitable for mid-to-high-end gears.
• Suitable for Large Workpieces: Worktable with high load-bearing capacity for large-diameter, disc, and hub gears; offers stable clamping and convenient loading/unloading.
• High Degree of Automation: Equipped with CNC system to perform gear indexing, automatic feeding, and multi-axis linkage for high machining efficiency and good consistency.
• Wide Application Range: Can machine a wide range of modules; used in gear manufacturing for reducers, construction machinery, wind power, machine tools, etc.
