CNC gear-cutting machine YD31266/YDZ3126（CDR）

vertical

Overview
The machine is designed for high-volume gear hobbing for passenger cars, commercial vehicles, construction machinery and gear reducers. Machining accuracy can reach GB/T10095.1-2008 grade 6.

Main performance and features

• Six-/seven-/eleven-axis, four‑axis linked high-speed dry-cut gear hobbing machine suitable for efficient, dry machining.
• Vertical layout: column performs horizontal movement to achieve radial feed for high-efficiency hobbing operations.
• Full-sealed guards, fast chip evacuation and dry cooling system ensure good thermal stability and dimensional consistency.
• Tool and workpiece spindles with direct-drive transmission provide a short drive train and high transmission accuracy; high-rigidity rolling bearings enable high-speed, high-rigidity, heavy-load dry cutting for medium-module gears.
• Optional single-machine loading/unloading units and automatic transfer magazine for automation and flexible production.
• Optional extruding chamfering and deburring units enable multi-process integration; optional gear-matching device supports precision hobbing after heat treatment.
• Control system configurable with Siemens or FANUC.
