{"id":"makino-a71nx","model_id":"a71nx","name":"Makino a71nx","summary":"The Makino a71nx is a 4-axis horizontal machining centre that uses a 500 mm square pallet and a CAT50 (HSK-A100 optional) spindle. It has 800 mm X, 750 mm Y and 830 mm Z travels, a 10,000 rpm spindle rated at 37 kW, and rapids of 50 m/min on X and Y and 60 m/min on Z. A direct-drive NC rotary B-axis table indexes 90° in one second and carries workpieces up to 1000 kg.","study_notes":["B-axis is a 360° direct-drive NC rotary table (DD NCRT) with 90° indexing time of 1 second.","Cutting feedrate is 50,000 mm/min.","Maximum workpiece size is ø900 mm x 1,000 mm.","ATC capacity is 60 tools, expandable to 136, 187 or 299.","Tool-to-tool change time is 1.7 s and chip-to-chip time is 3.6 s, both for tools of 20 kg or less.","Maximum tool diameter is 300 mm; maximum tool weight is 20 kg, or 30 kg with limitations.","Spindle duty rated torque is 512 Nm.","Inertia Active Control (IAC) monitors B-axis motor load, estimates fixture weight and adjusts acceleration and deceleration of the B and Z axes.","A Vision type broken tool sensor in the ATC magazine checks drills, taps and other single-point tools.","Tapping time is reduced by 20% compared with the previous model.","Machine construction uses a robust casting design and large roller-type linear guides; the way covers are a single-piece design and the tool-change arm is dual-supported."],"safety_notes":[],"sources":[{"url":"https://www.makino.com/en-us/machine-technology/machines/horizontal-4-axis/a71nx","title":"a71nx","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":13,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"makino","controllers":[],"axes":4,"travel_x_mm":800,"travel_y_mm":750,"travel_z_mm":830,"spindle_max_rpm":10000,"spindle_power_kw":37,"spindle_taper":"CAT50 (HSK-A100 opt)","rapid_traverse_m_min":60,"tool_capacity":60,"table_length_mm":500,"table_width_mm":500,"table_load_kg":1000,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/makino-a71nx","license":"https://creativecommons.org/licenses/by/4.0/"}
