Brother Speedio U500Xd1

The Brother Speedio U500Xd1 is a five-axis 30-taper machining center: 500 × 400 × 300 mm (19.7 × 15.7 × 11.8 in) of linear travel, an A axis that tilts from 120 to -30°, a 360° C axis on a ø260 mm (ø10.2 in) table, a 10,000 rpm BT30 spindle and a magazine of 14, 21 or 28 tools under Brother's CNC-D00 control.

The rotary table defines what fits. It carries 100 kg (220 lb) with an inertia limit of 1.8 kg·m² (6151 lb·in²); a bracketed 2.6 kg·m² (8885 lb·in²) is also listed without a stated condition. A ø260 mm table holds a compact vise, a zero-point plate or a small fixture, and the part plus workholding must be balanced as well as light, because inertia, not weight, limits how fast the table can swing. The A range of 120° one way and 30° the other lets the spindle reach the sides and part of the underside of a part in one clamping.

With the table tilted, vertical room shrinks quickly, and the spindle nose to table range here is 145 - 445 mm (5.7 - 17.5 in). Tools may be up to 250 mm (9.8 in) long and 110 mm (4.3 in) in diameter, but long tools and a tall part on a tilted table will not both fit, so check the clearance on the CAM model before quoting a job.

The A axis indexes at 50 rpm and the C axis is listed at 75 (60) rpm. Positioning accuracy is 0.006 - 0.020 mm (0.00024 - 0.00079 in) on X, Y and Z and 28 sec or less on A and C, with repeatability of < 0.004 mm (0.00016 in) and 16 sec or less respectively. The spindle runs to 10,000 rpm with 16,000 rpm optional, rated 10.1 kW for 10 min and 7.1 kW continuous. Tool to tool is 0.6 sec and chip to chip 1.2 sec with 14 or 21 tools.

The machine weighs 2,650 kg (5,843 lb), stands 2,748 mm (108.2 in) tall and has a footprint of 61.4 x 79.8 in. It needs AC 200 to 230 V three-phase, 9.5 kVA and 55 L/min of air at 0.4 - 0.6 MPa.
