How much does the Breton Ultrix E3 cost?
Price estimate
We do not have a price for the Breton Ultrix E3 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Breton Ultrix E3 moves the Ultrix idea, 5-axis milling and turning on a trunnion table under a gantry, up to parts weighing 2,500 kg (5,511 lb). Linear travels are 1,700 mm (66.9 in) in X, 1,600 mm (63.0 in) in Y and 1,000 mm (39.4 in) in Z.
Symmetry is the practical gain over the smaller model. The A axis tilts from -120° to 120°, so the table can present either side of a part to the vertical spindle. Breton points out a side effect that operators value: with the table tilted, chips fall away and the part can be cleaned.
Loading is from above. The top bellows open completely for an overhead crane, which at this payload is the only sensible way to load. The work area is clad in stainless steel and all axes are pressurised against contamination.
For turning, the E3 has a 450 mm (17.7 in) turning bar stroke, double that of the Breton Ultrix E2 at 225 mm (8.9 in), which lets the bar reach down inside a deep casing. Table speed is 500 rpm in S6, and the maximum torque row in the table block reads 2,700 Nm (1,991.5 lb-ft). The interface is Capto C8.
Two entries in the E3 column should be confirmed with Breton. The rotary table diameter is printed as 1,000 mm (39.4 in), smaller than on the E2, and the C axis travel is not printed cleanly. Rapids are 50 m/min (1,969 ipm) in all three linear axes; A turns at 30 rpm and C at 60 rpm, the slowest rotary speeds of the three versions.

Strengths & Limitations
Strengths
- Rotary table payload of 2,500 kg (5,511 lb)
- A axis tilting from -120° to 120°, to both sides
- 450 mm (17.7 in) turning bar stroke for deep internal turning
- Top bellows open completely for loading with overhead cranes
- Rapids of 50 m/min (1,969 ipm) in X, Y and Z alike
Limitations
- Rotary axes are the slowest in the range: 30 rpm in A and 60 rpm in C, against 50 rpm and 100 rpm on the Breton Ultrix E3 HD
- Rotary table diameter is printed as 1,000 mm (39.4 in), which needs confirming against the travels
- No milling spindle power or speed in the version table
- Capto C8 only in the taper row; the Breton Ultrix E3 HD lists HSK-T100

Frequently Asked Questions
01
The rotary table payload is 2,500 kg (5,511 lb). That is the same as the Breton Ultrix E3 HD and well above the 1,500 kg (3,307 lb) of the Breton Ultrix E2.
02
X is 1,700 mm (66.9 in), Y is 1,600 mm (63.0 in) and Z is 1,000 mm (39.4 in). The A axis tilts from -120° to 120°. The table does not print the C axis travel cleanly for this version, so take it from the maker's documents.
03
Travels and payload are the same. The Breton Ultrix E3 HD lists a maximum torque in S6 of 4,200 Nm (3,097.9 lb-ft) against 2,700 Nm (1,991.5 lb-ft) here, faster rotary axes, an HSK-T100 taper and a rotary table speed of 450 rpm.
04
The numerical control section lists Siemens Sinumerik One and Heidenhain 640. Tool stores of several types can be fitted, all compatible with the compact tool changer built into the machine column.
