GROB Systems has introduced its G750 5-axis universal machining centre, which offers high quality industrial manufacturing milling for large parts. 

The G750 provides high productivity, optimized availability, and significant flexibility. It offers a compact design that features optimized access and superior maintainability, with available round-the-clock service.

The G750’s unique 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 offers maximum stability by minimizing the distance between the guides and the machining point (TCP). The G750’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 5-sided machining, as well as 5-axis simultaneous interpolation, with a swivel range of 230 degrees in the A-axis and 360 degrees in the B axis.

The machine is available with a variety of powerful tilting rotary table versions with the latest torque motor technology and optimized dynamics. Users can choose between models with T-slots arranged in parallel (standard) or optional pallet clamping system.

Spindles offered range 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 convincing 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 the machining process and avoiding damage. Additional single and double disk type tool magazines are available for the G750, providing fast chip-to-chip times, a smaller space requirement and optimized accessibility.

Available automation options include a pallet changer system and customer-specific automation solutions. GROB software solutions are available to optimize and analyze the machine kinematics of the G750 and minimize deviations down to the finest detail.

An extensive range of accessories increases include a high pressure fluid cutting system, decentralized work area mist collecting system, and an oil skimmer that helps keep cutting fluid as clean as possible.
