5-Axis Aerospace Machining Capabilities

5-axis aerospace machining achieves complex surface and multi angle feature machining in one clamping by simultaneously controlling X/Y/Z three-axis linear motion and A/B two rotation axes, avoiding error accumulation caused by multiple clamping and significantly improving part accuracy and production efficiency.

Our core equipment includes:

MG Mori DMU 65 5-axis linkage machining center (stroke 650 × 650 × 550mm, spindle speed up to 24000 rpm)

Mazak Variaxis i-800 5-axis vertical machining center (stroke 800 × 800 × 700mm, equipped with automatic tool changing system)
