## Study notes

- Working travels are 1,250 mm (X), 920 mm (Y), and 1,160 mm (Z); maximum axis speeds are 60/50/60 m/min.
- Positioning accuracy is 0.006 mm in X/Y/Z; interference diameter is 1,350 mm.
- Chip-to-chip time t1 is 4.8 s according to VDI 2852, relative to spindle speed.
- Table load is stated as 950/- kg without/with pallet (A-/B-axis); the with-pallet value is not given.
- Motorized spindle versions are HSK-A100 at 340 Nm/6,000 rpm, 344 Nm/6,000 rpm, 340 Nm/10,000 rpm, 575 Nm/9,000 rpm, and 1,400 Nm/7,200 rpm.
- A crankcase machining example uses aluminium alloy, an 18,000 rpm motorized spindle, and 29 kW/34.6 Nm.
- Control options are SIEMENS (standard) and FANUC (option); no specific controller model is named.
- Tool magazine is chain-type with expandable tool pockets.
- GROB Spindle Diagnostics (GSD) monitors motorized spindle condition; SiS detects tool clamping faults caused by chips from 10 μm.
- The G700 is designed for wet and dry machining and is built from modular G-series assemblies.
- Loading options include top loading with agile loading gantry, Cartesian linear gantry, or Cartesian linear gantry with telescope; front loading with automatic sliding changer or swiveling changer.
- Axes decoupling divides motion axes into tool side and part side.
