Grob Systems’ GP1350 five-axis portal milling machining center is designed for a wide variety of manufacturing tasks, including large components, complex geometries and maximum precision. The GP1350 features optimal versatility in a compact footprint.

The GP1350 offers a broad XYZ working travel of 55 × 77 × 43" (1,400 × 1,950 × 1,100 mm) to accommodate large parts. The machine performs reliably on components with a maximum workpiece diameter of 69" (1,750 mm) and a maximum workpiece height of 65" (1,650 mm) while supporting a maximum load of up to 3.6 tons. The tool magazine has capacity for up to 408 tools and a double row allocation enables ergonomic and efficient setup of several tools at the same time. With the option of integrating pallet changers, pallet storage systems and autonomous loading systems, the GP1350 can be fully automated and is equally suitable for production processes ranging from single to multipart series.

A combination of powerful spindles, a robust table and dynamic axis movements enable the GP1350 to machine a wide variety of materials economically. The universal milling head with an undercut of -2.5 degrees significantly reduces setup times and saves valuable production time, while the compact design of 20 (l) × 18 (w) × 12 (h) feet (6,150 × 5,300 × 3700 mm) enables manufacturing large parts with a minimal footprint.

With its high load-bearing capacity, precise portal structure and automation options, the GP1350 offers users stable processes, reduced scrap rates and high production reliability. The GP1350 is well suited for a wide range of industries such as tool, die and mold, energy technology, aerospace and the automotive industry.

“The GP1350 offers a practical way to machine large, complex parts in a compact, automation-ready platform. It allows manufacturers to expand capability without the space and integration challenges typically associated with portal milling systems,” says Derek Schroeder, universal machines sales and proposals manager, Grob Systems Inc.
