The spindle oscillates the tool at amplitudes up to 15 µm through an HSK-E32 interface, which the document states reduces process forces by up to 50% compared with conventional machining. Linear drives move the X, Y and Z axes over strokes of 220 mm, 370 mm and 290 mm for machining workpieces up to Ø 220 x 283 mm.","study_notes":["ULTRASONIC technology is integrated via an HSK-E32 interface that superimposes tool rotation with amplitudes up to 15 µm.","Document states process forces are reduced by up to 50%, feed rates increase, surface finishes reach Ra < 0.1 µm, and tool life increases depending on requirements.","High-frequency spindles are listed as HSK-32 at 42,000 rpm standard, with an optional HSK-32 spindle up to 60,000 rpm; the spindle taper field records the HSK-32 spindle.","Linear drives give acceleration up to 1.2 g; the machine has a FEM-optimized cast bed and a temperature management system.","Maximum workpiece size is Ø 220 mm diameter by 283 mm height (9 in x 11 in).","C-axis speed is 150 rpm as standard, with an optional 1,500 rpm C-axis.","Control and software alternative stated in the document is SIEMENS; no matching controller entry exists in the reference list.","Location accuracy/repeatability, rapid traverse rates and machine weight are not stated in the document."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/ultrasonic/ultrasonic-precision/ultrasonic-20-linear-3rd","title":"ULTRASONIC 20 linear 3rd Generation - ULTRASONIC Machines - DMG MORI","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":10,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"dmg-mori","controllers":[],"travel_x_mm":220,"travel_y_mm":370,"travel_z_mm":290,"spindle_max_rpm":60000,"spindle_taper":"HSK-32","table_load_kg":15,"joints":[{"name":"A","range_min_deg":-93,"range_max_deg":130}],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-ultrasonic-20-linear-3rd-generation","license":"https://creativecommons.org/licenses/by/4.0/"}
