Fully Automated, Six-Sided Multifunction Machining

July 15, 2021
New 715 Series mill-turn machine is a fully automated design for producing complex parts for medical, aerospace, energy, and automotive sectors.

Recently, CHIRON GROUP demonstrated its new 715 Series machining center, designed for complete machining of all six sides of complex parts. In terms of its applications, the machine is slotted between the vertical Chiron FZ 08 S mill/turn precision+ machining center and the Stama MT 733 machining center and incorporates part-handling automation and storage functions.

Matthias Efinger, Chiron systems engineer R&D, said, the design goal was “to create a machining center designed for autonomous processing on all six sides, rounding off the Chiron Group bar-machining portfolio and fully bridging the gap between the FZ 08 S mill/turn precision+ and MT 733.”

The 715 Series is designed for fully automated, complete machining tasks in the medical technology, aerospace, energy, and automotive sectors. The part-size range is bars up to Ø 65 mm or chuck parts up to Ø 200 mm, with maximum workpiece weight of 20 kg.

Continuous machining process. Two versions of the new machining center are available:  Chiron MT 715 and Chiron MP 715. (MT stands for “mill/turn” and MP is for “multi profile.”)

Both machines include a direct-drive 20,000-rpm milling head, a horizontal main spindle, and a matched, opposing counter spindle to permit continuous multifunctional machining on all six sides of a part in a single set-up. This capability is used to machine hip stems, turbine blades, and extrusions for chassis or battery storage.

Both machines accommodate 128 tools and include integrated workpiece handling and workpiece storage. This supports fully automated, lower-cost manufacturing of workpieces in small and medium batch sizes. Loading and unloading of the tool magazine during machining is possible.

High levels of automation. The new machine platform is available to integrate digital systems from the Chiron SmartLine Portfolio, including automatic condition monitoring, integrated machine and process diagnostics, machining simulation, preventive machine protection in every mode of operation, remote diagnostics and remote maintenance, and intuitive operation.

Within the Chiron Group portfolio there are a range of options for machining workpieces with up to a 200 mm diameter and a length of up to 500 mm, for milling and turning off the bar, or milling off the bar or from profile. Learn more at
