The Grob Systems G550 is a compact, rigid, and highly flexible horizontal machining center with many spindle and table configuration options.  The most flexible 5-axis model (with A/B table) enables single setup machining of 5 sides as well as the most complex 5-axis simultaneous 3-D surfaces as well as multi-angled holes, forms and profiles.

G550 – Universal Machining Center
The G550 Universal Machining Center adds to the successful G series and opens up an even larger application range for the current G modules. The modules of the G550 series come, like all modules of the G series, from the same standard component program. The G550 is characterized by its compact design and allows for outstanding visibility into and access to the working areas.

Horizontal spindle arrangement
An optimized chip removal is achieved due to the vertical arrangement of the part traveling axis. The compact dimensions of the machine are a result of our unique design for the spindle position in X and Z axis and the Y-movement of the workpiece.  The unusually long Z-axis stroke (40″) provides even more range than most other models in the class.

Spindle and Table Options
Models are available with HSK-A63, CAT 40, and HSK-A100 spindle type. Top spindle RPM from 9,000 up to 30,000 are available. Impressive torque and horse power curves provide outstanding power for heavy milling of difficult materials.
Workpieces up to 1,763 lbs can be machined using horizontal or vertical table with A or B or A/B axes. Certain types of components and machining may lend itself more favorably to a horizontal or vertical configuration table and Grob makes that option available.  Pallet system options add to the system flexibility to dramatically reduce non cutting time during part change. Non cutting time during cycle is minimized perhaps more than any other machine in the market with ultra-fast rapid rates up to 3,144 IPM in the Z-axis.
