Brother Speedio HU550Xd1

The Speedio HU550Xd1 is a five-axis Brother BT30 machine with 550 x 500 x 400 mm (21.7 x 19.7 x 15.7 in) of travel, a ø400 mm (15.7 in) table on a tilting A axis (30 to -120°) and a 360° B axis, and a 30-tool magazine. Its table lists the distance from spindle centre to table and from spindle nose to table centre, the layout of a horizontal-spindle machine with a tilting table.

Size is the main difference from the Speedio U500Xd2, whose table is ø260 mm (ø10.2 in) and rated 100 kg (220 lb). Here the table is ø400 mm (15.7 in) and carries 200 kg (441 lb), and the axes travel further in every direction. Allowable table inertia is listed as 4.1 kg·m² (14,010 lb·in²), and the A axis is driven by two motors, given as 1.35+1.35 kW, which suits a larger fixture swinging through the tilt range.

Tooling limits are generous for a 30-taper machine. Tools may be 350 mm (13.7 in) long, 125 mm (4.9 in) in diameter and 4.0 kg (8.8 lb). With the spindle nose 150 - 550 mm (5.9 - 21.7 in) from the table centre at A 0°, long-reach tools can get into deep pockets on the side faces. The trade is change time: 1.3 s tool to tool and 2.5 s chip to chip, against 0.6 s and 1.3 s on the Speedio U500Xd2 with 14 or 21 tools.

The spindle is the same family as the U500Xd2: 12,000 rpm standard, a 10,000 rpm high-torque version or 20,000 rpm as options, 10.1 kW for 10 minutes and 7.0 kW continuous, tapping to 6,000 rpm. Rapids are 50 m/min (1,969 ipm) on X and 56 m/min (2,205 ipm) on Y and Z. Dual-contact tooling and through-spindle coolant are options.

The machine weighs 3,150 kg (6,945 lb), stands 2,682 mm (105.6 in) high and needs 1,557 x 2,744 mm (61.3 x 108.0 in) of floor, 45 L/min of air at 0.4 - 0.6 MPa and a 10.4 kVA supply. The control is Brother's CNC-D00.
