{"id":"makino-v300","model_id":"V300","name":"Makino V300","summary":"The Makino V300 is a vertical machining center with a 800 x 450 mm table and 650 x 450 x 350 mm X, Y and Z travel. It uses a 20,000 rpm HSK-63 spindle, box way construction on all axes, and a 20-position automatic tool changer. Thermal control systems, including cooled ball screws and slideway cooling, maintain accuracy over long machining cycles.","study_notes":["All axes use box way construction for vibration dampening and motion stability.","Spindle is designed and built by Makino with an integrated spindle and drive motor.","Spindle thermal control includes core cooling, under-race bearing lubrication, jacket cooling and an oil temperature controller.","The oil temperature controller also cools ball screw drive systems and controls slideway surface temperature.","Ball screws and support bearings are core cooled, and servo motor mounting brackets are thermally isolated.","Slideway system cooling covers all axes, including thermal control of the spindle mounting surface.","The Pro 6 eStabilizer function suppresses positioning errors caused by ambient temperature changes.","An optional bed and column stabilizer fills the castings with thermally conductive fluid to stabilize machine geometry.","SGI.6 motion control software offers ten operating modes.","An optional robot load door system is available for automated cell integration.","High accuracy laser tool setters and spindle probes for workpiece measuring are optional.","The control is the Makino Professional 6; optional ATC capacities are 40 and 60 tools, tool-to-tool time is 4.8 s, maximum tool diameter is 80 mm and maximum tool weight is 7 kg."],"safety_notes":["Collision Safeguard crash avoidance is integrated into the Pro 6 control to help prevent spindle, workpiece and fixture interference."],"sources":[{"url":"https://www.makino.com/en-us/machine-technology/machines/vertical-machining-centers-3-axis/v300","title":"Uncompromising accuracy and exceptional surface finishes","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":12,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"makino","controllers":[],"axes":3,"travel_x_mm":650,"travel_y_mm":450,"travel_z_mm":350,"spindle_max_rpm":20000,"spindle_taper":"HSK-63","rapid_traverse_m_min":20,"tool_capacity":20,"table_length_mm":800,"table_width_mm":450,"table_load_kg":300,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/makino-v300","license":"https://creativecommons.org/licenses/by/4.0/"}
