Jingdiao North America GRA400 VERTICAL MACHINING CENTER

Technical Description

The Jingdiao North America GRA400 is a vertical 5-axis CNC machining center engineered for high-precision production of complex components. The machine features a 15.7-inch diameter rotary worktable with a maximum workpiece capacity of 331 pounds, accommodating mid-sized parts for die and mold machining applications. Equipped with a high-speed vertical spindle rated at 24,000 RPM and delivering 21.5 Nm of torque, the GRA400 enables rapid material removal and fine surface finishing capabilities. The machine provides XYZ linear travel of 17.7 x 26.8 x 15.7 inches respectively, with rapid traverse rates of 590 IPM across all axes, supporting efficient cycle times. Its 5-axis configuration incorporates A and C rotational axes with ranges of -120° to 90° and 360° respectively, enabling simultaneous multi-axis machining of intricate geometries. The standard 36-tool carousel provides quick-change tooling for diverse machining operations without manual intervention. Advanced closed-loop control technology ensures micron-level dimensional accuracy and superior surface finish quality, making it suitable for precision molds, optical components, and complex hardware parts. Optional 6-axis capability is available for enhanced flexibility in part positioning and machining strategies.
