Brother Speedio H550Xd1

The Speedio H550Xd1 is a compact horizontal machining center on the BT30 taper, with 550 x 400 x 400 mm (21.7 x 15.7 x 15.7 in) of travel, a 360° B axis carrying a 400 mm (15.7 in) table rated 400 kg (882 lb), and a 30-tool magazine. It runs Brother's CNC-D00 control and a 12,000 rpm spindle as standard.

A horizontal layout changes how parts are machined rather than how big they can be. With the B axis indexing the part, four sides of a cube or a tombstone fixture can be reached in one clamping, and chips fall away from the work instead of collecting on it. The spindle centre sits 100 - 500 mm (3.9 - 19.7 in) above the table and the spindle nose 150 - 550 mm (5.9 - 21.7 in) from the table centre, which bounds the size of a fixture tower.

The nearest relative is the Speedio HU550Xd1, which adds a tilting A axis for five-axis work. The H550Xd1 gives that up and gets twice the table load in return: 400 kg (882 lb) against 200 kg (441 lb) on the Speedio HU550Xd1. It is also the lighter machine at 2,850 kg (6,284 lb), where the Speedio HU550Xd1 weighs 3,150 kg (6,945 lb). In exchange the Speedio HU550Xd1 has more Y, 500 mm (19.7 in) against 400 mm (15.7 in), and takes tools 350 mm (13.7 in) long against 250 mm (9.8 in) here.

Spindle options are a 10,000 rpm high-torque version and a 20,000 rpm version, rated 10.1 kW for 10 minutes and 7.0 kW continuous, with tapping to 6,000 rpm. Tools may be 125 mm (4.9 in) in diameter and 4.0 kg (8.8 lb). Tool changes take 1.3 s tool to tool and 2.7 s chip to chip, so on parts with many short operations the change time adds up. Rapids are 50 m/min (1,969 ipm) on X and 56 m/min (2,205 ipm) on Y and Z.

The machine takes 1,557 x 2,743 mm (61.3 x 108.0 in) of floor, is 2,497 mm (98.3 in) high, and needs 45 L/min of air at 0.4 - 0.6 MPa and a 10.4 kVA supply at AC 200 to 230 V.
