# GROB G700F

Hardware · `G700F` · verification: source checked

The G700F is a horizontal-spindle machining center built on the GROB G-series concept, intended for frame-structure and chassis parts in automotive work. Its working travels are 1,450 mm in X, 990 mm in Y and 1,035 mm in Z, with an interference diameter of 1,500 mm in the A- and B-axis. The narrow bridge gives access to the underside of the part for six-sided machining, and it can run stand-alone or linked to other machines.
