Hurco BX40Ui

The Hurco BX40Ui is a unique bridge-style 5-axis machining center with an integrated trunnion table, sitting in a category of its own within Hurco's lineup. The 'B' in BX stands for bridge — the column-and-bridge construction provides exceptional rigidity for a machine with 950 mm (37.4 in) of X travel and a 20,000 RPM HSK 63A spindle.

Travels are 950 x 549 x 500 mm (37.4 x 21.6 x 19.7 in). The bridge-style frame moves the spindle on overhead guides rather than a C-frame design, eliminating the overhang that limits accuracy on conventional vertical machining centers. The result is consistent rigidity across the entire work envelope, not just near the column.

The trunnion table is 398 mm (15.7 in) in diameter with a 250 kg (550 lb) capacity. B-axis tilts -30/+110 degrees (note the inverted notation from the VMX models) and C-axis rotates 360 degrees. The 6 T-slots at 14 mm x 60 degrees accept standard 5-axis workholding.

The 20,000 RPM HSK 63A spindle delivers 29 kW (38.9 hp) of peak power with 99.3 Nm (73.2 ft-lbs) of torque at 2,790 RPM. HSK 63A face-contact toolholding provides superior rigidity at high speeds, maintaining accuracy that CAT 40 tapers can't match above 12,000 RPM. The combination of bridge construction and HSK tooling makes this machine particularly strong for high-speed aluminum finishing.

The 30-tool ATC is slightly smaller than the 40-tool changers on VMX models but handles HSK 63A tooling with 80 mm max diameter and 300 mm max length. Rapids run 36 m/min (1,417 ipm) on all linear axes, with B and C axes at 25 RPM.

At 9,400 kg (20,723 lb), the BX40Ui is extremely heavy for its travel range — evidence of the bridge construction's mass. Floor space is 4,186 x 3,706 mm (165 x 146 in) and power draw is 57 KVA. WinMax control with full 5-axis capability is standard.

New pricing runs $280,000-$360,000. This machine occupies a unique niche between standard VMC-based 5-axis and premium European bridge-style platforms.
