Machine Comparison
Chiron 715 MT vs Chiron 831 MT
Chiron vs Chiron · Mill-Turn Machines
Summary
The Chiron 715 MT and the Chiron 831 MT are both mill-turn machines from Chiron that turn and mill a part complete. Chiron publishes no figures for this pair on a common basis, so this comparison has no spec table and names no winner on numbers.
The difference is in the shape of the part. The Chiron 715 MT is aimed at shaft and bar parts machined on both ends, with a counter spindle that takes full torque for second-side roughing and a milling spindle that swivels for angled work. The Chiron 831 MT is aimed at larger-diameter turned and milled parts, from bar or chuck, including turned blanks that need five-axis simultaneous milling.

Advantages
Chiron 715 MT
- Suited to long shaft and bar parts machined on both ends
- Counter spindle with full torque for second-side roughing
- Swivelling milling spindle for angled milling and drilling
Chiron 831 MT
- Suited to larger-diameter turned and milled parts
- Works from bar or chuck on one machine
- Five-axis simultaneous milling of turned blanks
Verdict
Choose by part shape. Long shaft and bar parts that need work on both ends belong on the Chiron 715 MT, with its counter spindle and swivelling milling spindle. Larger-diameter chucked parts and turned blanks that need five-axis simultaneous milling belong on the Chiron 831 MT. Chiron does not publish figures that line up for this pair, so check travel, bar capacity and spindle data on each machine's own page.
