{"id":"hermle-c-250-gen2","model_id":"C 250 GEN2","name":"HERMLE C 250 GEN2","summary":"The HERMLE C 250 GEN2 is a 5-axis vertical machining centre in the HERMLE Performance Line, built for milling workpieces up to Ø 450 mm and 355 mm high. Linear travels are 600 x 550 x 450 mm in X, Y and Z with 35 m/min rapid traverse, and the machine can be equipped with a swivelling rotary table (A axis ±115°, C axis) or a rigid 800 x 616 mm clamping table. It uses a pick-up tool changer with a 30-pocket magazine and spindles up to 20,000 rpm, controlled by a Heidenhain TNC7.","study_notes":["Spindle options: 15,000 rpm with SK 40 and 20 kW / 173 Nm at 20% c.d.f.; 16,000 rpm with HSK A 63 and 20 kW / 173 Nm; 20,000 rpm with HSK A 63 and 42 kW / 148 Nm.","Tool changer is a pick-up type with 30 magazine pockets and approx. 6 s chip-to-chip time; maximum tool length 300 mm, maximum tool weight 8 kg, maximum magazine load 120 kg.","Tool diameter in the magazine is Ø 80 mm, or Ø 125 mm with corresponding adjacent pocket allocation.","Optional additional magazines: ZM 30 (+30 pockets), ZM 50 (+50), ZM 88 k (+88), ZM 216 (+216, HSK A 63 only).","Control unit is a Heidenhain TNC7.","Positional uncertainty in X-Y-Z axes per ISO 230-2 is ≤ 0.006 mm, calculated at a constant ambient temperature of 20 °C ±1 °C.","Table variants: swivelling rotary table Ø 320 mm, swivelling rotary table Ø 450 x 360 mm, or rigid clamping table 800 x 616 mm; swivelling range ±115° for the swivelling tables.","Rotary speeds: swivelling axis A 25 rpm (one-sided drive), rotary axis C 40 rpm; table load 300 kg for the swivelling rotary table variants.","Max vertical table clearance 550 mm; max workpiece height 355 mm; collision circle (A-axis) in 0° position Ø 770 mm.","Linear acceleration X-Y-Z 6 m/s² and linear feed force X-Y-Z 5000 N.","Connected load: power consumption up to 43 kVA; compressed air 6 bar; hydraulics operating pressure 120 bar; cooling lubricant tank 800 l.","The machine can be transported without being dismantled and set up without a foundation."],"safety_notes":[],"sources":[{"url":"https://www.hermle.de/en/machining-centres-automation/models/machining-centre-c-250-gen2/","title":"Machining centre C 250 GEN2","accessed":"2026-10-26"},{"url":"https://www.hermle.de/fileadmin/website/5_NEWS-UND-MEDIA/5_2_Mediathek/Technische_Daten/Englisch/HERMLE_Technical-Data_C250-GEN2_2025_EN.pdf","title":"HERMLE Technical Data C250 GEN2 2025 EN","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":19,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"cnc_mill","manufacturer":"hermle","controllers":[],"axes":5,"weight_kg":8200,"travel_x_mm":600,"travel_y_mm":550,"travel_z_mm":450,"spindle_max_rpm":20000,"spindle_taper":"SK 40 / HSK A 63","rapid_traverse_m_min":35,"tool_capacity":30,"table_length_mm":800,"table_width_mm":616,"table_load_kg":1100,"supply_voltage":"400 V / 50 Hz | 460 V / 60 Hz","max_workpiece_diameter_mm":450,"joints":[{"name":"A","range_min_deg":-115,"range_max_deg":115},{"name":"C"}],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/hermle-c-250-gen2","license":"https://creativecommons.org/licenses/by/4.0/"}
