With the newly developed G150, GROB rounds off the bottom end of its universal machining center range. The G150 profits from market dominance in the automotive industry due to the modular G-series system, which has continuously defined the bar for productivity and process safety.
For complex components with highest standards, development of the G150 placed particular emphasis on spatial accuracy to achieve excellent surfaces and the highest form and position tolerances. This improvement is achieved via a groundbreaking calibration concept, an innovative cooling concept for all relevant components and high dynamic axis configuration stability. No compromises were made to the combination of outstanding ergonomics and perfect automation capacity for this. The G150 is optimally positioned for the precision engineering, medical technology, tool and mould manufacture, mechanical engineering and aerospace industries.
Accuracy for machining complex, high-precision components with maximum process reliability was the main focus during development of the G150.
The static accuracy has been further improved by an innovative setup method which brings the proven concept to a new level of basic mechanical accuracy.
Thermal stability is achieved via active cooling of all relevant components, which has been refined over many years, defining a new benchmark.
The dynamic accuracy is important for simultaneous 5-axis movement, for example. Both the speed as well as the accuracy were improved by consistently integrating the drive simulation into the development process from the beginning.
Process Reliability: The machine’s warm-up cycle is now individually adapted to the actual situation. The machine detects when production can be started and when to end the warm-up cycle autonomously based on the geometry parameters.
If recalibration is required, the calibration software detects this and notifies the operator accordingly. In combination with a pallet storage system, calibration can even be initiated completely automatically. Process reliability is integral at GROB, and not left to chance.
An important foundation for the success of the G-series is the unique combination of ergonomics suited to a workshop and perfect automation capabilities.
The machine is suitable for both a job shop environment as well as for series production. In combination with a pallet storage system, the machine can be used for prototypes in the early shift and then for series production at night, for example.
New additions to the modular options system are the HSK E40 spindle with up to 42,000 rpm and a compact table with central clamping. This makes the machine particularly attractive for new application areas such as medical technologies, with smaller parts and smaller tools.
As with the G350, G550 and G750 universal machining centers, the G150 with its outstanding axis concept. The horizontal spindle ensures that nothing can stop production. Excellent milling control and low tool wear are determined on the spindle side. This is why the Z-guides are closer to the part than in any other concept for this machine. This guarantees unparalleled metal-cutting performance completely independent of the Z-axis position.
The name GROB stands for the dedication of over 6,000 employees world-wide proud to be connected to it. Every customer issue is seen as having utmost significance, and no compromises are made in ensuring the customer’s complete satisfaction.
