GROB G320

The GROB G320 is a two-spindle machining center in the GROB G-series. Two parallel motorized spindles machine two parts simultaneously, and an optional pallet changer lets dissimilar part types be machined in parallel without change-over times. It is intended for manufacturing lines in the automotive sector.
