{"id":"dmg-mori-gm-20-6","model_id":"GM 20-6","name":"DMG MORI GM 20-6","summary":"The GM 20-6 is an automatic turning machine for medium and large-scale production of small components. It turns workpieces up to 25 mm diameter and 100 mm length, with a bar capacity of 25 mm, and its spindle reaches speeds up to 5,000 rpm. X-axis stroke is 42 mm and Z-axis stroke is 50 mm.","study_notes":["Machine construction is based on a frame or portal design to minimise distortion during machining.","Machine bed, main spindle and front-working tool carrier construction plus overhead bracing provide damping.","Workpieces are machined from the front, so no angle tools are required; front-working tools are guided on the central block.","Four compound-rest slides are provided for radial or straight turning.","Working stroke in all stations can be adjusted independently and steplessly.","All spindle bearings are oil cooled.","Adjustable minimum cycle time is under 1.4 seconds, including for double drop production."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/turning/horizontal-production-turning/gmc-gm/gm-20-6","title":"GM 20-6 - Horizontal Production Turning Machines and Lathes - DMG MORI","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":7,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_lathe","manufacturer":"dmg-mori","controllers":[],"travel_x_mm":42,"travel_z_mm":50,"spindle_max_rpm":5000,"max_turning_diameter_mm":25,"max_turning_length_mm":100,"bar_capacity_mm":25,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-gm-20-6","license":"https://creativecommons.org/licenses/by/4.0/"}
