CNC gear-cutting machine YD3126-CD

vertical

Overview
The YD3126-CD is a CNC composite machine designed for high‑volume gear production, combining hobbing and form‑milling operations. It is intended for gears used in passenger cars, commercial vehicles, construction machinery and reducers. Machining accuracy can reach Grade 6 according to GB/T10095.1-2008.

Main performance and features

• Thirteen‑axis, four‑linkage, high‑speed dry hobbing and form‑milling composite machine for efficient, high‑throughput processing.
• Four indexed workstations allow simultaneous hobbing and form‑milling on different stations to increase productivity.
• Vertical layout with column horizontal movement provides radial feed for efficient hobbing operations.
• Form‑milling is implemented using forming milling cutters with rolling‑cut method to combine multiple process steps.
• Full enclosed guarding, fast chip evacuation and dry cooling system ensure thermal stability and consistent part dimensions.
• Hob spindle and worktable spindle use direct‑drive transmission for short drive trains and high transmission accuracy; supported by high‑rigidity rolling bearings to enable dry cutting of medium‑module gears.
• Optional single‑machine loading/unloading devices and automatic transfer magazine support automation and flexible production.
• Control system can be configured with Siemens or FANUC.
