Precision and Efficiency in Compressor Guide Vane Machining with Jingdiao GRA400
We’re proud to showcase the incredible capabilities of our Jingdiao GRA400 5-axis high-speed machining center in manufacturing aluminum compressor guide vanes. Here’s what sets us apart:
Workpiece Specs: Radius 252mm × 94mm, aluminum alloy 6061, pre-turned blanks.
Machining Features: 7 sets of blades and flow channels, blade dimensions:
Length: 39.8mm
Width: 40.5mm
Thinnest section: 1.6mm
Precision: Blade profile accuracy less than 0.08mm, surface roughness Ra less than 0.8μm.
Advanced Tools: 12°-R1mm tapered ball-end mill, 5-axis linked plunge milling for fine finishing.
Efficiency: Achieved a 30% improvement in processing time.
Currently, two GRA400 machines are producing these components with stable monthly output, supporting customers in their ongoing R&D and full-machine production efforts.
