GROB Unveils Compact 5-Axis Portal Machining Centre for Large, High-Precision Components!
GROB Systems has expanded its advanced machining portfolio with the introduction of the GP1350, a compact 5-axis portal milling machining centre engineered to handle large components and complex geometries with exceptional precision. The machine was officially unveiled during the company’s 100-year anniversary in-house exhibition at its headquarters in Mindelheim, underscoring GROB’s continued focus on innovation in high-performance manufacturing solutions.
The GP1350 is designed to bridge the gap between large-part machining capability and efficient use of shopfloor space. Despite its relatively compact footprint of approximately 20 × 18 × 12 ft., the machine delivers impressive working ranges, with X-, Y-, and Z-axis travels of 55 inches, 77 inches, and 43 inches respectively. This allows manufacturers to machine sizable and complex workpieces with ease. The system can accommodate components up to 69 inches in diameter and 65 inches in height, with a maximum load capacity of 3.6 tons, making it suitable for industries requiring heavy-duty, high-precision machining such as aerospace, energy, and general engineering.
A key highlight of the GP1350 is its flexibility in production. The machine is capable of supporting both single-part manufacturing and multi-part series production, making it an ideal solution for companies looking to balance customisation with scalability. To further enhance productivity, the system can be integrated with advanced automation solutions, including pallet changers, pallet storage systems, and autonomous mobile robot loading. This enables seamless, unattended operations and helps manufacturers move towards fully automated production environments.
Tool management is another area where the GP1350 stands out. It features a tool magazine with a capacity of up to 408 tools, arranged in a double-row configuration. This design not only maximises tool availability for complex machining tasks but also improves ergonomics and reduces setup times, allowing operators to work more efficiently and minimise downtime.
Performance-wise, the machine combines high-performance spindles, a rigid table structure, and dynamic axis movement to deliver consistent machining quality across a wide range of materials. Whether working with metals commonly used in heavy industries or more specialised materials, the GP1350 ensures stability, accuracy, and surface finish quality. Its universal milling head further enhances versatility, featuring an undercut capability of minus 2.5 degrees. This allows for greater accessibility to difficult-to-reach areas of a workpiece, reducing the need for multiple setups and improving overall productivity.
By combining compact design with large working capacity and advanced automation readiness, the GP1350 offers manufacturers a powerful solution for modern production challenges. It enables companies to maximise output, reduce floor space requirements, and maintain high levels of precision—all critical factors in today’s competitive manufacturing landscape.
