{"id":"grob-g720f","model_id":"G720F","name":"GROB G720F","summary":"The GROB G720F is a two-spindle horizontal machining center for frame structure and chassis parts, and it machines two parts in parallel. Its X/Y/Z working travels are 1,450/1,200/1,035 mm, with maximum axis speeds of 80/50/100 m/min. Spindle options use HSK-A63 and HSK-A100 interfaces, and loading can be manual or automatic front or top loading.","study_notes":["Maximum axis speeds are 80 m/min in X, 50 m/min in Y, and 100 m/min in Z.","Chip-to-chip time t1 to VDI 2852 is 2.9 s, stated relative to a rotational speed.","Position accuracy in X/Y/Z is 0.01 mm.","Table diameter is 512 mm; table load is 2x635 kg with pallet and 2x750 kg without pallet.","Total weight is 35,000 kg without pallet changer and 45,000 kg with pallet changer.","Interference diameter is 2x1,500 mm.","Spindle versions: HSK-A63 at 47 Nm/12,000 rpm, 47 Nm/18,000 rpm, 83 Nm/12,000 rpm and 86 Nm/17,000 rpm; HSK-A100 at 185.5 Nm/12,000 rpm and 340 Nm/10,000 rpm.","Battery-tray example lists a motorized spindle at 18,000 rpm and 29 kW/34.6 Nm.","Tool magazine options are single disk-type and double disk-type.","Loading options include top-loading robot, Cartesian linear gantry, Cartesian linear gantry with telescope, and front-loading swiveling changer.","GROB Spindle Diagnostics (GSD) monitors motorized spindle condition; Chip-in-Spindle Detection System (SiS) detects tool clamping faults from 10 μm.","Machine can be used stand-alone or linked to other machines; axis arrangement uses horizontal spindle position."],"safety_notes":[],"sources":[{"url":"https://www.grobgroup.com/en/products/product-range/machining-technology/machining-centers-for-frame-structure-parts/g720f/","title":"G720F","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":5,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"grob","controllers":[],"travel_x_mm":1450,"travel_y_mm":1200,"travel_z_mm":1035,"spindles":2,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/grob-g720f","license":"https://creativecommons.org/licenses/by/4.0/"}
