{"id":"makino-edbv3","model_id":"EDBV3","name":"Makino EDBV3","summary":"The Makino EDBV3 is an EDM hole-drilling machine for blade and vane cooling holes and diffusors. It drills fully submerged in de-ionized water and has X/Y/Z travels of 370/270/500 mm, a 2-axis rotary table, and a 24-position automatic tool changer. A break-through detection circuit stops back-striking when drilling into hollow cavities.","study_notes":["Uses Makino Hyper-i control with Windows 7 and a 24-inch class high-definition touch interface.","Control includes pre-programmed cycles for diffuser shapes, intelligent electrode length management, and multiple graphical pick-up cycles.","Die Guide and Electrode tooling are loaded and exchanged together as an assembled unit; combined ATC and AGC exchange time is within 30 seconds.","The dielectric reservoir is integrated into the base casting; water quality is maintained by an on-board chiller, water filtration, and de-ionization systems.","The programmable 3-sided Rise and Fall work tank provides unrestricted access to the work tank for load/unload and automation.","Maximum workpiece weight is 5 kg standard, with a 15 kg optional rotary table.","Tank size is 790 x 611 mm (31.1 x 24.1 in).","The machine is configured with an integrated 2-axis rotary table for positioning the workpiece to access multiple sides in a single setup."],"safety_notes":["Break-through detection circuit prevents back-striking when EDM drilling into hollow cavities; detection occurs within 1 second or 0.040 in (1.0 mm) of depth.","Fully submerged machining in de-ionized water minimizes water over-spray and eliminates the splash guards used on traditional EDM drilling machines.","Middle Guide system supports long electrodes during machining to prevent whipping or bending."],"sources":[{"url":"https://www.makino.com/en-us/machine-technology/machines/edm-hole-drilling/edbv3","title":"EDBV3","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_edm","manufacturer":"makino","controllers":[],"travel_x_mm":370,"travel_y_mm":270,"travel_z_mm":500,"rapid_traverse_m_min":5,"tool_capacity":24,"table_load_kg":5,"joints":[{"name":"A","range_max_deg":360},{"name":"B","range_min_deg":-110,"range_max_deg":30}],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/makino-edbv3","license":"https://creativecommons.org/licenses/by/4.0/"}
