{"id":"dmg-mori-ctx-beta-1250-tc-4a","model_id":"CTX beta 1250 TC 4A","name":"DMG MORI CTX beta 1250 TC 4A","summary":"The CTX beta 1250 TC 4A is a DMG MORI turn-mill machine that combines turning with milling using a compactMASTER turn-mill spindle and a second tool carrier. Its linear strokes are 490 mm in X, 200 mm in Y and 1,200 mm in Z, and it accepts workpieces up to 340 mm diameter and 1,185 mm long, with 102 mm bar capacity. The B-axis swivels ±110° so tools can approach the workpiece at an angle.","study_notes":["Second tool carrier is a turret with 12 or 16 driven stations (VDI40 / VDI30); a DirectDrive turret version runs at 10,000 rpm with 80 mm Y-stroke.","compactMASTER turn-mill spindle: 12,000 rpm, 22 kW, 120 Nm; a high-speed version is available at 20,000 rpm.","B-axis has a swivel range of ±110° and a Direct Drive with positioning accuracy < 1 µm.","Y-stroke of ±100 mm is stated for external machining operations.","Machining compartment accepts a circular diameter up to 500 mm; 400 mm long workpieces can be bored or turned horizontally; 470 mm outer diameter with the B-axis vertical and a 70 mm tool.","Linear scales are fitted in the travelling column axes X1/Y1/Z1 and in the X2 axis of the turret, optionally in Y2/Z2 (turret) and Z3 (counter spindle).","Main and counter spindles use water-cooled integrated spindle motors; the turret drive, the X/Y/Z motors and the lower turret are cooled.","Guideways are size 45 and ball screws are Ø 40 mm.","Control alternatives are listed only as SIEMENS; no specific control model is given in the document."],"safety_notes":[],"sources":[{"url":"https://en.dmgmori.com/products/machines/turning/turn-mill/ctx-tc/ctx-beta-1250-tc-4a","title":"CTX beta 1250 TC 4A - Turn & Mill Machines - DMG MORI","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":7,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"cnc_multitasking","manufacturer":"dmg-mori","controllers":[],"travel_x_mm":490,"travel_y_mm":200,"travel_z_mm":1200,"max_turning_diameter_mm":340,"max_turning_length_mm":1185,"bar_capacity_mm":102,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dmg-mori-ctx-beta-1250-tc-4a","license":"https://creativecommons.org/licenses/by/4.0/"}
