GROB Systems brings the G-Series universal machining centers to IMTS this September. Based on a horizontal machining center platform popular with automotive OEMs, GROB universal machines are designed for manufacturers in medical, aerospace, die/mold and other industries.

The smallest machine in the line, G-350, requires less floor space than other machines with the same work zone. GROB’s original spindle design accommodates very long tools (365 mm/14.3 in) with no interference, even with the largest work piece size. The maximum part is a 600 mm cylinder with 500 mm in height (Ø 23.6 in x 19.7 in). G-350 will be paired with the Schuler 12-pallet system to demonstrate automated scheduling and handling. 
The mid-size G-550T will be shown with the turning option for parts up to 900 mm in cylinder (Ø 35.4 in). The high-speed table rotates at 800 rpm while compensating for uneven loads. Maximum part height is 730 mm (28.7 in), and longest tool is 500 mm (19.6 in). Both models feature the GROB-designed and built table with 225 degrees of rotation in the A axis, and continuous 360 degrees in B axis. It is possible to completely invert the table for upside-down machining while chips simply free-fall away from the part. 
GROB Systems, winner of 2013 GM Supplier of the Year Award, is a family-owned company that builds machines in the US and Germany. All replacement parts and factory service are available from the 300,000 square foot facility in Bluffton, Ohio. For more information, go to www.grobgroup.com or visit booth S-9490 at IMTS.
