Vertical Gear Hobbing Machine

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.

Stable Structure: Adopting a vertical column + worktable layout, it boasts high rigidity and low vibration, making it suitable for machining large-diameter, large-module gears.

High Machining Accuracy: It can accurately machine spur gears, helical gears, worm gears, and synchronous gears, with stable tooth profile and direction accuracy, meeting the needs of mid-to-high-end gears.

Suitable for Large Workpieces: The worktable has a high load-bearing capacity, suitable for machining large-diameter, disc, and hub gears. It offers stable clamping and convenient loading and unloading.

High Degree of Automation:Equipped with a CNC system, it can automatically perform gear indexing, automatic feeding, and multi-axis linkage, resulting in high machining efficiency and good consistency.

Wide Application Range: It can machine a wide range of modules and is widely used in gear manufacturing for reducers, construction machinery, wind power, machine tools, etc.
