The 2016 Grob G550 is a 5-axis universal horizontal machining center engineered for stable, high-precision cutting across practically every material, from aluminum and steel to titanium and hardened tool steel. This unit pairs a Siemens Sinumerik 840D control with an HSK-A63 16,000 rpm, 43 hp motorized spindle, a 50-tool magazine, and a Renishaw probe for automated setup and in-process measurement. Its horizontal spindle position maximizes Z-axis reach and lets chips fall clear of the work zone, while three linear axes (800 mm X, 1,020 mm Y, 970 mm Z) combine with a tilting rotary table (A-axis -185 to +45 degrees, continuous 360-degree B-axis) to machine complex parts on five sides in a single setup. High-pressure coolant, a mist collector, compressed air through the spindle, and an additional grid-pattern pallet round out a production-ready cell built for exceptional rigidity and 0.006 mm positioning accuracy.
Set against the smaller G350 in the same 5-axis milling-center line, the G550 scales the identical machine concept up to a larger work envelope, a bigger tilting rotary table, and a 900 mm interference diameter, so shops can take on heavier and physically larger workpieces without changing platforms. That added capacity, paired with the same horizontal-spindle rigidity, full 5-sided access, and probing-ready Siemens control, makes the G550 the more capable choice for aerospace structures, energy components, and larger mold and die work.
