Grob Systems has introduced the G550 five axis universal machining centre.
Grob says that the G550 features a unique milling concept that enables stable and precise cutting of most materials used in the die and mould industries, such as cores, cavities, lifters and manifolds.
The G550 machine concept includes a horizontal spindle position that permits the longest possible Z-travel path and optimum chip fall. The arrangement of the three linear axes provides stability by minimizing the distance between the guides and the machining point (TCP). The G550’s tunnel concept allows the largest possible component to be swiveled and machined within the work area without collision—even with extremely long tools. Three linear and two rotary axes permit five sided machining, as well as five axis simultaneous interpolation, with a swivel range of 230 degrees in the A axis and 360 degrees in the B axis.
The G550 is controlled by the GROB4Pilot machine control panel, which offers a multi-functional user interface. The production process is digitally mapped on the control panel, from the CAD model through to the NC simulation.
The G550 is available with a variety of tilting rotary table versions with current torque motor technology and optimized dynamics. Users can choose between models with T-slots arranged in parallel (standard) or optional pallet clamping system.
A broad range of spindles are offered, ranging from 6,000 to 30,000 (rpm) and 47 to 575 (Nm). The Grob motorized spindle with cross-feed allows complex internal and external contours to be manufactured with controllable tools. It offers system rigidity, high cutting speeds for machining contours, and low tool costs. The Grob chip-in-spindle detection system (SiS) detects tool clamping faults, optimizing machining and reducing damage. Additional single and double disk type tool magazines are available for the G550, providing fast chip-to-chip times, a smaller space requirement and optimized accessibility.
Automation options include linear and rotary pallet storage systems as well as a pallet changer system. Grob software solutions are available to optimize and analyze the machine kinematics of the G550 and minimize deviations in detail.
