2015 CHIRON MILL 1250 VERTICAL MACHINING CENTERS

Technical Description

The 2015 Chiron MILL 1250 is a 3- to 5-axis CNC vertical machining center from Chiron Group SE of Tuttlingen, Germany, representing the long-bed 1,250 mm X-travel configuration of the Chiron MILL series. The traveling-column architecture traverses over a fixed long table, enabling machining of large structural components, aerospace profiles, and multi-fixture production setups without the limitations of a moving table. The spindle delivers approximately 31 to 34 kW (42 to 46 HP) and is configurable from 12,000 RPM standard to 20,000 RPM in the High Speed Plus variant, through SK-40 or HSK-A63 tooling. X-axis (column) travel extends 49.2 inches (1,250 mm), Y-axis travel reaches 33.1 inches (840 mm), and Z-axis travel is 21.7 inches (550 mm). Tool magazine capacity reaches up to 163 tools via chain magazine, supporting complex long-run automated production. Control is provided by the Siemens 840D sl as standard, with Fanuc and Heidenhain available as customer options. A swivel-head option enables 4th/5th-axis contouring for complex surface work. Overall machine dimensions and weight were not published in accessible OEM documentation and should be requested from Chiron Group directly. The MILL 1250 is deployed in aerospace structural machining, large mold and die applications, and automotive body and chassis component production.
