How much does the Chiron 715 MT cost?
Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Chiron. Configuration moves it a long way.
Overview
The Chiron 715 MT is a mill-turn center with a long X axis: 1,550 mm of X travel against 210 mm of Y and 480 mm of Z, a main and a counter turning spindle, and one milling spindle that swivels ± 110°. The long stroke suits a machine with turning spindles at both ends of the job, and Chiron rates the two almost identically.
Two spindle sizes are offered, and the bar capacity row gives 65 mm and 102 mm in the same order. The smaller main spindle runs to 4,800 rpm with 270 Nm on a DIN ISO 702-1 A2 Nr. 6 nose. The larger runs to 3,500 rpm with 495 Nm on a Nr. 8 nose. The counter spindle carries the same torque and nose sizes, at 4,800 rpm or 3,000 rpm. Equal torque on both sides means the second operation can rough as hard as the first, which a light pick-off spindle cannot do.
Milling is done by a 20,000 rpm, 100 Nm spindle with an HSK-T63 interface. The tower magazine holds 64 to 176 tools and changes chip to chip in 3.9 s. Tools may be 80 mm in diameter, or 160 mm with adjacent pockets empty, 450 mm long and 5.0 kg.
Rapids are 60 m/min in X and Z and 40 m/min in Y, with 10 m/s² of acceleration on all three. The 08 Series Mill-Turn, with 210 × 200 × 360 mm travels and bar capacity up to 65 mm, stops where the 715 MT starts: 65 mm is the smaller of its two bar sizes.

Strengths & Limitations
Strengths
- Main and counter turning spindles with the same maximum torque, 270 Nm or 495 Nm depending on spindle size
- Bar capacity of 65 mm or 102 mm
- 1,550 mm of X travel for long parts and for work at both turning spindles
- Milling spindle with 20,000 rpm, 100 Nm and a ± 110° swivel range
- Tower magazine for 64 to 176 tools, with tools up to 450 mm long
Limitations
- Y travel is 210 mm, which limits off-centre milling on larger diameters
- Maximum tool weight is 5.0 kg, which excludes heavy boring bars and large cutter bodies
- Y rapid traverse is 40 m/min, below the 60 m/min of X and Z
- The larger turning spindle is limited to 3,500 rpm, and to 3,000 rpm on the counter side

Frequently Asked Questions
01
Chiron lists 65 mm and 102 mm. The turning spindle rows give two matching sets of figures: 4,800 rpm and 270 Nm with a DIN ISO 702-1 A2 Nr. 6 nose, and 3,500 rpm and 495 Nm with a Nr. 8 nose. The sheet gives them in the same order as the bar sizes.
02
In torque, yes: both are rated 270 Nm or 495 Nm depending on the size. Speed differs on the larger size, where the main spindle is rated 3,500 rpm and the counter spindle 3,000 rpm. On the smaller size both run to 4,800 rpm.
03
A single milling spindle with an HSK-T63 interface, 20,000 rpm and 100 Nm, swivelling ± 110°. Its tools come from a tower magazine holding 64 to 176 tools, with a chip-to-chip time of 3.9 s.
04
80 mm in diameter with neighbouring pockets occupied, 160 mm with them empty, 450 mm in length and 5.0 kg in weight. The weight limit is the one to check first: a long boring bar can stay inside 450 mm and still exceed 5.0 kg.
05
Rapid traverse is 60 m/min in X, 40 m/min in Y and 60 m/min in Z. Acceleration is 10 m/s² on each of the three axes. On the 1,550 mm X axis the 60 m/min rate is what keeps long repositioning moves short.
