You Ji AH Series Horizontal CNC Turning Centres

Heavy-Duty Performance for Oil & Gas and Energy Applications

The You Ji AH Series of CNC turning centres are engineered for high-torque, large-diameter, heavy-duty machining — purpose-built for the oil & gas, aerospace, and power generation sectors. Combining robust construction with cutting-edge control options, the AH Series is ideal for turning long shafts, tubing, flanges, and complex components with precision and repeatability.

Key Features

Massive Spindle Bore Options: Choose from 6”, 9”, or 12” spindle bores for increased bar capacity and power.
Rigid Meehanite One-Piece Base: Heavy-duty casting with FEA-optimised structure for vibration damping, thermal stability, and long-term accuracy.
Advanced C & Y Axis Capabilities: C-axis with ±0.01° positioning and optional Y-axis for true multi-tasking operations including keyway milling and off-centre drilling.
High-Torque Live Tooling: Optional live spindle (up to 4000 rpm) for powerful milling, drilling, and contouring operations.
Customisable Lengths: Models available with turning lengths of 1000mm, 2100mm, and 3200mm to suit a wide range of applications.
Big Bore Chucking System: Front and rear chucking increases support for long shaft machining and reduces workpiece distortion.
Operator-Focused Design: 45° slant bed and 55° cross-slide for improved ergonomics and easier tool setting.
