{"id":"makino-a51nx","model_id":"a51nx","name":"Makino a51nx","summary":"The Makino a51nx is a horizontal machining center with a 400 x 400 mm pallet and X/Y/Z travels of 560/640/640 mm. It uses a 14,000 rpm spindle with CAT40 (HSK-63) taper and carries up to 60 tools in its automatic tool changer. The machine is controlled by the Pro6 control and is intended for ferrous and non-ferrous part production.","study_notes":["The Pro6 control includes Process Tracer and Feed Optimizer, which are components of Makino iKnowledge software.","A machine health monitoring system is included for proactive maintenance and downtime reduction.","The standard B-axis is direct-drive; the machine has 1G-axis acceleration.","Cutting feedrate is 50,000 mm/min.","Maximum workpiece size is ∅630 mm x 900 mm.","Tool-to-tool time is 0.9 s and chip-to-chip time is 2.2 s.","Maximum tool length is 430 mm for CAT and 420 mm for HSK; maximum tool diameter is 170 mm and maximum tool weight is 12 kg.","Optional spindle speed is 20K; optional ATC capacities are 40, 134, 219 and 311 tools.","The machine uses roller-type linear guides and one-piece X- and Z-axis way covers.","A dual-supported tool-change arm is used."],"safety_notes":[],"sources":[{"url":"https://www.makino.com/en-us/machine-technology/machines/horizontal-4-axis/a51nx","title":"a51nx","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":11,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"makino","controllers":[],"travel_x_mm":560,"travel_y_mm":640,"travel_z_mm":640,"spindle_max_rpm":14000,"spindle_taper":"CAT40 (HSK-63)","rapid_traverse_m_min":60,"tool_capacity":60,"table_length_mm":400,"table_width_mm":400,"table_load_kg":400,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/makino-a51nx","license":"https://creativecommons.org/licenses/by/4.0/"}
