High Precision 5-Axis Universal Machining Center

GROB Systems, Inc. offers the G150 5-Axis Universal Machining Center, the smallest horizontal machining center (HMC) to date for the company in its modular G-series Universal line. "The G150 provides high precision, complex machining in a compact size with a smaller work envelope. Featuring direct and absolute position encoders in all axes and an innovative machine cooling process, the machining center provides exceptional contouring accuracy," said a company spokesperson.

"We are pleased to offer manufacturers of complex components, found in industries such as medical, aerospace, mold and die, energy and automotive, with an efficient, high precision GROB machining solution in an economic footprint, that is ideal for light metal removal as well as heavy-duty machining," said Derek Schroeder, Universal Machines, Sales & Proposals Manager, GROB Systems, Inc.

The GROB G150 is equipped with features that provide a wide range of benefits, including optimal chip evacuation via its a horizontal spindle position, which permits the longest possible Z-travel path in its machine class, the company reported. Three linear and two rotary axes enable five-sided machining and simultaneous interpolation. The machine's axis arrangement makes overhead machining possible, offering operators optimum accessibility for a broad range of part sizes. Tool changes occur outside of the work area, which eliminates chip interference during tool changes. In addition, a tool brush cleans the tool shank prior to the tool being inserted into the spindle, and a coolant flushing system pushes chips out of the work area and through the conveyor.

The basis of the drive concept is two symmetrically arranged ball screws. Torque motors in the A- and B-axes help ensure dynamic and wear-free machining of parts. For maximum machine rigidity, the arrangement of the three linear axes minimizes the distance between the guides and the machining point. The axis arrangement permits a large swivel range of 230° in the A-axis. Also, a tunnel concept allows the largest possible component-even when using extremely long tools-to be machined within the work area without collision. The GROB G150 has working travels in the X, Y, Z axes of 450 mm/670 mm/665 mm and maximum speeds of 50/40/60 m/min. A 380 mm diameter table can handle loads up to 485 lbs. (220 kg) with a pallet changer and up to 551 lbs. (250 kg) without a pallet changer. Machine dimensions are 17'5" (length), 7'3" (width) and 7'8" (height).

For even higher productivity, the G150 can be partially or fully automated via GROB's line of automation solutions, including pallet changers, pallet storage systems and robot cells.
