Milling Center Model


Universal CNC Horizontal Milling Machine andMachining Center

PRODUCT
Grob G-350 5-Axis Universal Machining Center

The Grob Systems G350 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.

G350 - Universal Machining Center
The new G350 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 G350 series come, like all modules of the G series, from the same standard component program. The G350 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 (31.6") provides even more range than most other models in the class. 

Spindle and Table Options 
Models are available with HSK-A63, CAT 40, spindle type. Top spindle RPM from 12,000 up to 28,000 are available. Impressive torque and horse power curves provide outstanding power for heavy milling of difficult materials. 
Workpieces up to 836 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 3,540 IPM in the Z-axis.
