{"id":"grob-g150","model_id":"G150","name":"GROB G150","summary":"The GROB G150 is a 5-axis universal machining center with three linear axes (X, Y, Z) and two rotary axes (A and B) and a horizontal spindle position. It performs 5-sided machining and 5-axis simultaneous interpolation on complex parts, with working travels of 450 mm in X, 670 mm in Y and 665 mm in Z. Direct, absolute position encoders in all axes support a positioning accuracy of 0.006 mm.","study_notes":["Positioning accuracy is 0.006 mm in X, Y and Z; all axes use direct, absolute position encoders.","Axis arrangement: three linear axes and two rotary axes (A and B) allow 5-sided machining and 5-axis simultaneous interpolation.","Max. speeds are 50 m/min in X, 40 m/min in Y and 60 m/min in Z.","Interference diameter is 580 mm.","Table diameter is 380 mm; table load is 250 kg without pallet and 220 kg with pallet.","Total machine weight is 13,400 kg without pallet changer and 15,400 kg with pallet changer.","Chip-to-chip time t1 is 2.6 s according to VDI 2852, relative to spindle speed.","Motorized spindle options: HSK-E40 17.4 Nm / 42,000 rpm; HSK-A63 82.8 Nm / 12,000 rpm; HSK-A63 206 Nm / 16,000 rpm; HSK-A63 46.6 Nm / 21,000 rpm; HSK-A63 63 Nm / 30,000 rpm.","Tool length for the single disk-type tool magazine is 265 mm (HSK-E40 / HSK-A63); single, double and triple disk-type magazines are offered.","A-axis swivel range is 230 degrees; torque motors drive the A- and B-axes, and the Y-axis uses two symmetrically arranged ball screws with weight compensation.","GROB4Pilot control panel: multi-touch display, 3D spacemouse, trackball, CAD/CAM programming at the machine and access to the GROB-NET4Industry platform. An energy efficiency package is offered for machines with SIEMENS control system.","GROB Spindle Diagnostics (GSD) monitors motorized spindle condition; the Chip-in-Spindle Detection System (SiS) detects tool clamping faults caused by chips between the plain surface and spindle nose from 10 micrometres."],"safety_notes":[],"sources":[{"url":"https://www.grobgroup.com/en/products/product-range/universal-machining-centers/milling-centers/g150/","title":"Universal machining center G150","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":8,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"grob","controllers":[],"axes":5,"travel_x_mm":450,"travel_y_mm":670,"travel_z_mm":665,"spindle_taper":"HSK-E40 / HSK-A63","rapid_traverse_m_min":60,"screen_size_in":24,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/grob-g150","license":"https://creativecommons.org/licenses/by/4.0/"}
