Brother Speedio S300Xd2 vs Brother Speedio S500Xd2
Brother Industries vs Brother Industries · Vertical Machining Centers
Summary
The Brother Speedio S300Xd2 and Speedio S500Xd2 are the same 30-taper machine in two widths. Both have 450 mm (17.7 in) of Y travel, a 600 × 450 mm table, a 250 kg (551 lb) load, a 12,000 rpm BT30 spindle, 0.6 / 0.7 sec tool changes and 50 / 50 / 56 m/min rapids.
The one table difference that matters is X travel: 500 mm (19.7 in) on the S500Xd2 against 300 mm (11.8 in) on the S300Xd2. The S300Xd2 is the more compact machine, with a 1,080 × 2,161 mm (42.5 × 85.1 in) floor space against 1,560 × 2,081 mm (61.4 × 81.9 in), and it is slightly lighter at 2,350 kg (5,181 lb) against 2,400 kg (5,292 lb).

Advantages
Brother Speedio S300Xd2
- Narrower floor space: 1,080 × 2,161 mm against 1,560 × 2,081 mm
- Slightly lighter at 2,350 kg (5,181 lb) against 2,400 kg (5,292 lb)
Brother Speedio S500Xd2
- 500 mm (19.7 in) X travel against 300 mm (11.8 in)
- Room for longer parts or more fixtures on the same 600 × 450 mm table
Verdict
Spindle, table and speed are the same, so buy for X travel and floor space. Choose the Brother Speedio S300Xd2 for small parts in dense robotic cells, where a 1,080 mm wide machine fits more spindles into the floor. Choose the Speedio S500Xd2 for mid-size aluminum and brass parts, or for several parts fixtured side by side, where 500 mm of X travel is needed.
