GROB G520 VERTICAL MACHINING CENTER

This CNC machine features working travels of 29.53 in (X), 33.07 in (Y), and 38.19 in (Z), allowing substantial range for multi-axis machining operations. It achieves maximum speeds of 295.28 in/min (X), 246.06 in/min (Y), and 328.08 in/min (Z), facilitating high-throughput machining cycles. The interference diameter is 2x31.42 in, defining effective work envelope constraints between spindles spaced 31.50 in apart, suitable for simultaneous dual-spindle machining. Chip-to-chip time is minimized to 2.6 seconds, enhancing overall productivity by reducing tool change delays. The machine offers exceptional positioning accuracy of 0.00024 in across all linear axes (X/Y/Z), supporting high-precision manufacturing requirements. The base weight without the pallet changer is 57,760 lb, increasing to 70,950 lb when equipped, indicating robust construction and stability for heavy-duty machining. The table loading capacity accommodates up to 4,630.42 lb on the A-axis and 1,376.81 lb on the B-axis with clamping fixtures and parts, enabling reliable handling of sizable workpieces. These specifications collectively indicate a high-performance CNC machining center optimized for precision, speed, and versatility in complex manufacturing environments, including operations requiring rapid spindle changes and dual-spindle interference management.
