Brother Speedio R450X1

The Speedio R450X1 is a three-axis BT30 machining center with 450 x 320 x 305 mm (17.7 x 12.6 x 12.0 in) of travel on a 600 x 300 mm (23.6 x 11.8 in) table rated 120 kg (265 lb). It is from Brother's X1 generation and is discontinued, so it is bought used.

The table shape tells you how to use it. At 600 mm (23.6 in) long and 300 mm (11.8 in) deep, with 450 mm (17.7 in) of X, it suits a row of small vises or a long, narrow fixture rather than a wide plate. The 120 kg (265 lb) rating covers aluminium fixtures and small steel parts, not heavy cast fixtures or a large rotary table.

Tool change time depends on the magazine. With 14 tools the change is 0.8 s tool to tool and 1.6 s chip to chip; with 22 tools it is 0.9 s and 1.7 s. Tools are limited to 200 mm (7.9 in) long, 80 mm (3.1 in) in diameter and 3.0 kg (6.6 lb), so this is a machine for drills, taps and small end mills. All three axes rapid at 50 m/min (1,969 ipm) and cut at up to 30,000 mm/min (1,181 ipm).

The spindle runs to 10,000 rpm, or 16,000 rpm as an option, and is rated 10.1 kW for 10 minutes and 6.7 kW continuous, with tapping to 6,000 rpm. Dual-contact tooling and coolant through the spindle were options. The later SPEEDIO R450X2 has the same travels, table and tool magazine, with 7.1 kW continuous against 6.7 kW and a weight of 2,670 kg (5,886 lb).

Installation is straightforward: 1,400 x 2,654 mm (55.1 x 104.5 in) of floor, 2,588 mm (101.9 in) of height, 2,700 kg (5,954 lb), 50 L/min of air at 0.4 - 0.6 MPa and an AC200V ±10% supply.
