Brother Speedio S500Xd2

The Brother Speedio S500Xd2 is a 30-taper vertical machining center with 500 × 450 mm (19.7 × 17.7 in) of X and Y travel and a choice of Z: 300 mm (11.8 in) as standard or 380 mm (15.0 in) as an option. It has a 600 × 450 mm (23.4 × 17.7 in) table, a 12,000 rpm BT30 spindle in standard form, up to 28 tools and Brother's CNC-D00 control.

The Z option is the decision that shapes this machine. With the standard Z the spindle nose sits 180 - 480 mm (7.1 - 18.9 in) above the table; the optional Z widens that to 150 - 530 mm (5.9 - 20.9 in). The gain at the top lets a taller part, a rotary unit with a part on it, or a long drill in a tall vise fit under the spindle, and the lower start keeps short tools within reach of thin parts. Tools can be up to 250 mm (9.8 in) long, so on the standard Z a long tool and a tall fixture compete for the same space. The cost is small: chip-to-chip goes from 1.2 / 1.3 to 1.3 / 1.4 (14 or 21 tools / 28 tools) with the taller axis.

Spindle choices run from a high-torque 10,000 rpm option through the 12,000 rpm standard spindle to 20,000 and 27,000 rpm options. The table gives one power rating for them, 10.1 kW for 10 min and 7.0 kW continuous. The 27,000 rpm spindle raises tapping speed to 8,000 from 6,000 rpm. Coolant through the spindle and a dual-contact taper are options.

The table carries 250 kg (551 lb), or 400 kg (881 lb) with the option, and the Y stroke of 450 mm (17.7 in) gives room for deeper fixtures than the 400 mm (15.7 in) of the Speedio S500Xd1. Tool to tool is 0.6 sec with 14 or 21 tools and 0.7 sec with 28.

For installation, allow 1,560 × 2,081 mm (61.4 × 81.9 in) of floor, 2,529 mm (99.6 in) of height and 2,400 kg (5,292 lb) of weight. Supply is AC 200 to 230 V three-phase at 10.4 kVA, with 40 L/min of air at 0.4 - 0.6 MPa.
